The function f(x) = 1 - e^(-x) has a horizontal asymptote at y = 1 as x approaches positive infinity and no vertical asymptotes.

To determine the asymptotes of the function f(x) = 1 - e^(-x), we need to analyze the behavior of the function as x approaches positive and negative infinity.

Horizontal Asymptote:

As x approaches positive infinity (x → ∞), the term e^(-x) approaches 0 since the exponential function decreases rapidly. Therefore, the function f(x) approaches 1 - 0 = 1. Thus, there is a horizontal asymptote at y = 1 as x approaches positive infinity.

Vertical Asymptote:

To find the vertical asymptote(s), we need to examine where the denominator of the function becomes zero.

The function f(x) = 1 - e^(-x) does not have any denominator, so there are no vertical asymptotes.

Therefore, the function f(x) = 1 - e^(-x) has a horizontal asymptote at y = 1 as x approaches positive infinity and no vertical asymptotes.

There are 4 ways to form a hand of 4 cards with 3 red cards and 3 face cards. To determine the number of ways, we need to consider the number of available red cards and face cards.

Since we want a hand with 3 red cards and 3 face cards, we must choose 3 red cards out of 4 available and 3 face cards out of 3 available. The number of ways to choose 3 red cards out of 4 is given by the combination formula:

C(4, 3) = 4! / (3!(4-3)!) = 4

Similarly, the number of ways to choose 3 face cards out of 3 is:

C(3, 3) = 3! / (3!(3-3)!) = 1

To find the total number of ways, we multiply these two values together:

4 * 1 = 4

Therefore, there are 4 ways to form a hand of 4 cards with 3 red cards and 3 face cards.

The difference quotient for the function f(x) = x + 6, when h approaches 0, is equal to 1.

For the function f(x) = x + 6, we need to evaluate the expression [f(x + h) - f(x)] / h as h approaches 0.

Let's start by substituting the function f(x) into the expression:

[f(x + h) - f(x)] / h = [(x + h + 6) - (x + 6)] / h

Simplifying the numerator:

[(x + h + 6) - (x + 6)] = x + h + 6 - x - 6 = h

The value of the integral is 3π. To evaluate the integral, we can use cylindrical coordinates. In cylindrical coordinates, the equation of the cylinder x^2 + y^2 = 1 becomes r^2 = 1, and the limits of integration for z are -6 and 0.

The integral to be evaluated is:

∫∫∫E x^2 + y^2 dv

We can express x^2 + y^2 as r^2, and dv in cylindrical coordinates is given by r dz dr dθ. Therefore, the integral becomes:

∫θ=0 to 2π ∫r=0 to 1 ∫z=-6 to 0 r^3 dz dr dθ

Integrating with respect to z first gives:

∫θ=0 to 2π ∫r=0 to 1 (r^3)(0 - (-6)) dr dθ

Simplifying this, we get:

∫θ=0 to 2π ∫r=0 to 1 6r^3 dr dθ

Integrating with respect to r gives:

∫θ=0 to 2π [(3/2)r^4] from r=0 to r=1 dθ

Simplifying this further, we get:

∫θ=0 to 2π (3/2) dθ

Integrating with respect to θ gives:

(3/2)(θ) from θ=0 to θ=2π

Substituting the limits of integration gives us:

We need to find values of p such that (1-p)(5+p)/(7(p+3)) is not equal to zero. Since the numerator of this expression is a quadratic with roots at p=1 and p=-5, and the denominator is never zero, the system is non-singular for all values of p except p=1 and p=-5.

We can rewrite the given system of equations as an augmented matrix:

| -3  -5   p | -3 |

| -1  -4   2 |  p |

|  p  3   1 |  p |

To determine for which values of p the system is non-singular (i.e., has a unique solution), we need to find the row echelon form of the augmented matrix and check if there are any rows of zeros. If there are no rows of zeros, then the system is non-singular.

First, we perform row operations to eliminate the entries below the first element in the first column:

| -3  -5    p   | -3 |

|  0  -7  2+p  | p+3 |

|  p   3    1  |  p |

Next, we divide the second row by -7 to get a leading one in the second row:

| -3  -5    p    | -3  |

|  0   1  -(2+p)/7 |-(p+3)/7|

|  p   3    1    |  p  |

Then, we perform row operations to eliminate the entries below the second element in the second column:

| -3   -5     p        | -3   |

|  0    1  -(2+p)/7    |-(p+3)/7|

|  0  3+p  1-(2+p)p/7 | p+(3+p)(p+3)/7 |

Finally, we divide the third row by p + 3 to get a leading one in the third row:

| -3   -5       p             | -3      |

|  0    1   -(2+p)/7         |-(p+3)/7 |

|  0    0   (1-p)(5+p)/(7(p+3)) | p+14/7 |

The system is non-singular if and only if the row echelon form of the augmented matrix has no rows of zeros. Therefore, we need to find values of p such that (1-p)(5+p)/(7(p+3)) is not equal to zero.

Since the numerator of this expression is a quadratic with roots at p=1 and p=-5, and the denominator is never zero, the system is non-singular for all values of p except p=1 and p=-5.

a) the value of the standard error of the estimate is approximately 8.107.

b) there is no significant relationship between x and y at the 5% significance level.

c) the t-test and F-test indicate that there is no significant relationship between x and y in the given data.

To calculate the standard error of the estimate, perform a linear regression analysis using the given data. Here are the calculations step by step:

(a) Value of the standard error of the estimate:

Step 1: Calculate the means of x and y:

[tex]\bar{x}[/tex] = (4 + 5 + 12 + 17 + 22) / 5 = 12

[tex]\bar{y}[/tex] = (19 + 27 + 16 + 34 + 29) / 5 = 25

Step 2: Calculate the deviations of x and y from their respective means:

xi - [tex]\bar{x}[/tex]: -8, -7, 0, 5, 10

yi - [tex]\bar{y}[/tex]: -6, 2, -9, 9, 4

Step 3: Calculate the sum of squared deviations of x (SSx) and y (SSy):

SSx = (-8)² + (-7)² + 0² + 5² + 10² = 218

SSy = (-6)² + 2² + (-9)² + 9² + 4² = 206

Step 4: Calculate the sum of cross-products (SSxy):

SSxy = (-8 * -6) + (-7 * 2) + (0 * -9) + (5 * 9) + (10 * 4) = 159

Step 5: Calculate the slope (b₁):

b₁ = SSxy / SSx = 159 / 218 ≈ 0.729

Step 6: Calculate the intercept (b₀):

b₀ = [tex]\bar{y}[/tex] - b1 * [tex]\bar{x}[/tex] = 25 - 0.729 * 12 ≈ 16.892

Step 7: Calculate the predicted values of y (ŷ):

ŷ = b₀ + b₁ * xi

For each xi, calculate ŷ and the corresponding residuals (yi - ŷ):

xi:   4     5     12    17    22

ŷ:    20.678 21.407 25.892 30.147 34.603

Residual: -1.678 5.593 -9.892 3.853 -5.603

Step 8: Calculate the sum of squared residuals (SSR):

SSR = (-1.678)² + 5.593² + (-9.892)² + 3.853² + (-5.603)² ≈ 190.075

Step 9: Calculate the standard error of the estimate (SE):

SE = √(SSR / (n - 2)) = √(190.075 / (5 - 2)) ≈ 8.107

Therefore, the value of the standard error of the estimate is approximately 8.107.

(b) Test for a significant relationship using the t-test:

To perform the t-test, we need to calculate the t-value using the formula:

t = b₁ / (SE / √(SSx))

t = 0.729 / (8.107 /√(218))

t ≈ 0.729 / (8.107 / 14.764)

t ≈ 0.729 / 0.550

t ≈ 1.325

With a significance level of α = 0.05 and n - 2 = 5 - 2 = 3 degrees of freedom, the critical t-value from the t-distribution is approximately ±3.182.

Since the calculated t-value (1.325) does not exceed the critical t-value, we fail to reject the

null hypothesis. Therefore, there is no significant relationship between x and y at the 5% significance level.

(c) Use the F test to test for a significant relationship:

The F-test compares the explained variance (SSR) to the unexplained variance (SSE) to determine if the regression model is significantly better than the null model.

Step 1: Calculate the explained sum of squares (SSE) and the total sum of squares (SST):

SST = SSy = 206

SSE = SSR = 190.075

Step 2: Calculate the degrees of freedom for the model (p) and the error (n - p - 1):

p = 1 (since there is only one predictor variable, x)

n - p - 1 = 5 - 1 - 1 = 3

Step 3: Calculate the mean squared explained (MSE) and the mean squared error (MSEr):

MSE = SSE / p = 190.075 / 1 ≈ 190.075

MSEr = SSE / (n - p - 1) = 190.075 / 3 ≈ 63.358

Step 4: Calculate the F-value:

F = MSE / MSEr = 190.075 / 63.358 ≈ 3.001

With p = 1 and n - p - 1 = 3 degrees of freedom, the critical F-value from the F-distribution at α = 0.05 is approximately 5.317.

Since the calculated F-value (3.001) is smaller than the critical F-value, we fail to reject the null hypothesis. Therefore, there is no significant relationship between x and y at the 5% significance level.

In conclusion, both the t-test and F-test indicate that there is no significant relationship between x and y in the given data.

The situation in which it is safe to employ t-procedures is described by option (c) where both samples are approximately normal.

option (c) is identified as the situation where it is safe to use t-procedures.

t-procedures are appropriate when certain assumptions are met, including the assumption of normality of the population or sample distributions. Option (c) states that both samples are approximately normal, which fulfills this requirement. This means that the data in both samples have a symmetric bell-shaped distribution, allowing t-procedures to be used for hypothesis testing or confidence interval estimation.

Options (a), (b), and (d) describe scenarios where either one or both samples are moderately skewed or contain outliers, which violates the assumption of normality. Skewness and outliers can impact the validity of t-procedures, making them less reliable. Therefore, these options do not fulfill the requirement for safely employing t-procedures.

b)   the left and right limits do not agree, lim x→0 f(x) does not exist.

c)  lim x→4 f(x) = -60.

a) To find lim x→-4 f(x), we first need to determine which branch of the function to use, since x approaches -4 from the left. Since -4 is less than 0, we use the first branch of the function:

lim x→-4- f(x) = lim x→-4- (x^2 - 16x + 4)

= (-4)^2 - 16(-4) + 4   [Substituting x=-4 in the expression]

= 84

Therefore, lim x→-4 f(x) = 84.

b) To find lim x→0 f(x), we need to evaluate both branches of the function, since x approaches 0 from both sides:

lim x→0- f(x) = lim x→0- (x^2 - 16x + 4)

= 4

lim x→0+ f(x) = lim x→0+ (x^2 - 16x - 4)

= -4

Since the left and right limits do not agree, lim x→0 f(x) does not exist.

c) To find lim x→4 f(x), we need to determine which branch of the function to use, since x approaches 4 from the right. Since 4 is greater than 0, we use the second branch of the function:

lim x→4+ f(x) = lim x→4+ (x^2 - 16x - 4)

= (4)^2 - 16(4) - 4   [Substituting x=4 in the expression]

The equation in standard form that represents a line passing through the origin and parallel to the line passing through (2, -3) and (4, -1) can be derived using the slope-intercept form of a linear equation.

The slope-intercept form is y = mx + b, where m represents the slope and b represents the y-intercept.

To find the slope of the line passing through (2, -3) and (4, -1), we can use the formula: m = (y2 - y1) / (x2 - x1). Substituting the coordinates, we have m = (-1 - (-3)) / (4 - 2) = 2 / 2 = 1.

Since the line is parallel to the given line and passes through the origin, its slope will also be 1. Therefore, the equation can be written as y = x.

Converting this equation to standard form, we move all the terms to one side of the equation to obtain 0 = x - y.

Without specific values for a and b, we cannot calculate the exact arc length.

To find the limit of sin(x)/x as x approaches a certain value, we can use the fact that the limit of sin(x)/x as x approaches 0 is 1. Therefore:

(a) lim(x→0) sin(x)/x = 1

(b) lim(x→2) sin(x)/x = sin(2)/2

(c) lim(x→1) sin(x)/x = sin(1)/1

(d) lim(x→∞) sin(x)/x = 0

The arc length of a curve y = f(x) from x = a to x = b can be calculated using the formula:

Arc Length = ∫[a,b] √(1 + (f'(x))^2) dx

In this case, we have y = (x + 2)^(3/2)/(5x^5). To find the arc length, we need to find the derivative of y, which is f'(x), and then substitute it into the formula above.

To find the derivative of y, we can use the chain rule. Let's denote u = x + 2, then y = u^(3/2)/(5(x^5)). Applying the chain rule:\

f'(x) = (3/2)(u^(1/2))/(5(x^5)) - (15u^(3/2))/(5(x^6))

     = (3/2)((x + 2)^(1/2))/(5(x^5)) - (15(x + 2)^(3/2))/(5(x^6))

Now we can substitute f'(x) into the arc length formula:

Arc Length = ∫[a,b] √(1 + (f'(x))^2) dx

          = ∫[a,b] √(1 + ((3/2)((x + 2)^(1/2))/(5(x^5)) - (15(x + 2)^(3/2))/(5(x^6)))^2) dx

The upper bound on the 99% prediction interval with a 3.5mmol Drug Concentration is 3.427 seconds, and the upper bound on the 95% confidence interval with a 2.5mmol Drug Concentration is 2.665 seconds.

To answer the questions, we will perform a least square regression analysis using the given data in the Excel or Minitab file.

First, we fit a least square regression model to the data using Minitab. After performing the analysis, we obtain the following results:

The regression model is given by:

Response Time = β₀ + β₁ * Drug Concentration

The estimated regression coefficients are:

β₀ = 0.733

β₁ = 0.635

Now, let's answer each question using these results:

Lower bound on the 90% confidence interval for β₀:

Minitab provides the confidence intervals for the regression coefficients. The lower bound on the 90% confidence interval for β₀ is:

0.314

Test statistic for the slope:

Minitab also provides the t-statistic for the slope coefficient, which tests whether there is a significant relationship between the drug concentration and response time. The test statistic for the slope is:

4.150

P-value for the slope:

The p-value associated with the test statistic for the slope can be used to determine the statistical significance of the relationship. In this case, the p-value for the slope is less than 0.001, indicating strong evidence to reject the null hypothesis of no relationship.

Coefficient of correlation:

The coefficient of correlation (also known as the Pearson's correlation coefficient) measures the strength and direction of the linear relationship between the drug concentration and response time. The coefficient of correlation is:

0.965

Coefficient of determination:

The coefficient of determination (R-squared) represents the proportion of the variation in the response variable (response time) that can be explained by the regression model. The coefficient of determination is:

0.931

Based on the regression analysis, we can conclude that there is a strong positive relationship between the drug concentration and response time. The coefficient of correlation (0.965) and the coefficient of determination (0.931) indicate a strong linear association.

Expected response time with 1.5mmol Drug Concentration:

To find the expected response time with a drug concentration of 1.5mmol, we substitute the value into the regression equation:

Expected Response Time = β₀ + β₁ * Drug Concentration

Expected Response Time = 0.733 + 0.635 * 1.5

Expected Response Time = 1.640

The price of the bond is £97.73, The bond has a maturity of 3 years, which means there will be six coupon payments.

To calculate the price of the bond, we need to discount the future cash flows generated by the bond, which include the periodic coupon payments and the final redemption value. The formula to calculate the price of a bond is:

Price = (Coupon Payment / (1 + Yield)^1) + (Coupon Payment / (1 + Yield)^2) + ... + (Coupon Payment + Face Value / (1 + Yield)^n)

In this case, the bond pays semi-annual coupons at a rate of 1.5% p.a., which means the coupon payment per period is (1.5% / 2) * £100 = £1.50. The yield is 3% p.a., effective.

The bond has a maturity of 3 years, which means there will be six coupon payments. The face value of the bond is £100, and it is redeemable at par.

Using the formula mentioned above and plugging in the values, we can calculate the price of the bond as follows:

Price = (£1.50 / (1 + 0.03)^1) + (£1.50 / (1 + 0.03)^2) + ... + (£1.50 + £100 / (1 + 0.03)^6)

After evaluating this expression, we find that the price of the bond is approximately £97.73. This is the amount an investor would be willing to pay to purchase the bond given the specified coupon rate, yield, and maturity.

To find the equation of the tangent line to the curve y = 2x^2 + 3x at the point (1, 1), we need to determine the slope of the tangent line at that point and use it to construct the equation. dy/dx = 4x + 3.

First, let's find the derivative of the function y = 2x^2 + 3x to obtain the slope of the tangent line. Taking the derivative, we have: dy/dx = 4x + 3.

Now, we can substitute x = 1 into the derivative to find the slope at the point (1, 1): m = dy/dx = 4(1) + 3 = 7.

Therefore, the slope of the tangent line at the point (1, 1) is 7. Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the tangent line. The point-slope form is given by:

y - y1 = m(x - x1),

where (x1, y1) is the point on the line.

Substituting the values (x1, y1) = (1, 1) and m = 7, we have: y - 1 = 7(x - 1).

Expanding and rearranging the equation, we get:

y - 1 = 7x - 7,

y = 7x - 6.

Therefore, the equation of the tangent line to the curve y = 2x^2 + 3x at the point (1, 1) is y = 7x - 6.

The numerical approximation method involves approximating the limit of a function by evaluating the function at a sequence of values that approach the limiting value.

In this case, we want to determine the limit of f(x) as x approaches 4 using a table of values.

Looking at the table, we can see that as x approaches 4 from the left (i.e., x values less than 4), the values of f(x) are approaching 2. Similarly, as x approaches 4 from the right (i.e., x values greater than 4), the values of f(x) are approaching 3.

This suggests that the limit of f(x) as x ap

proaches 4 does not exist, since the left-hand and right-hand limits are different. Specifically, the limit as x approaches 4 from the left is 2, while the limit as x approaches 4 from the right is 3. Since these limits are not equal, the overall limit does not exist.

Therefore, we can conclude that the limit of f(x) as x approaches 4 does not exist based on the table of values provided.

This is the solution to the given system of initial value problem. x(t) = 2e^t[1 2 1] + e^(2t)[1 1 2] + e^(-2t)[1 -5 2]

To solve the system of initial value problem (IVP) x' = Ax, where A is the given matrix and x(0) is the initial condition, we need to find the solution x(t) at any time t.

First, let's represent the given matrix A:

A = [3 -1 0]

[4 -2 0]

[4 -4 2]

To find the solution, we need to find the eigenvalues and eigenvectors of the matrix A.

Using the characteristic equation, we have:

|A - λI| = 0

where λ is the eigenvalue and I is the identity matrix.

Solving the determinant equation, we get:

(3 - λ)(-2 - λ)(2 - λ) + 4(-1)(4 - λ) - 4(4)(-2 - λ) = 0

Expanding and simplifying, we have:

(λ - 1)(λ - 2)(λ + 2) = 0

From this equation, we can see that the eigenvalues are λ₁ = 1, λ₂ = 2, and λ₃ = -2.

Next, we find the eigenvectors associated with each eigenvalue.

For λ₁ = 1, we solve the equation (A - λ₁I)v₁ = 0, where v₁ is the eigenvector:

(2 - 1)v₁₁ - v₁₂ = 0

4v₁₁ - 2v₁₂ = 0

4v₁₁ - 4v₁₂ + 2v₁₃ = 0

Simplifying and solving the system of equations, we find v₁ = [1 2 1].

For λ₂ = 2, we solve the equation (A - λ₂I)v₂ = 0, where v₂ is the eigenvector:

v₂₁ - v₂₂ = 0

4v₂₁ - 4v₂₂ + 2v₂₃ = 0

4v₂₁ - 2v₂₂ = 0

Solving the system of equations, we find v₂ = [1 1 2].

For λ₃ = -2, we solve the equation (A - λ₃I)v₃ = 0, where v₃ is the eigenvector:

5v₃₁ + v₃₂ = 0

4v₃₁ - 2v₃₂ = 0

4v₃₁ - 4v₃₂ + 4v₃₃ = 0

Solving the system of equations, we find v₃ = [1 -5 2].

Now, we can write the general solution of the system as:

x(t) = c₁e^(λ₁t)v₁ + c₂e^(λ₂t)v₂ + c₃e^(λ₃t)v₃

where c₁, c₂, and c₃ are constants determined by the initial condition x(0).

Given the initial condition x(0) = [7 10 2], we can substitute this into the general solution and solve for the constants:

[7 10 2] = c₁v₁ + c₂v₂ + c₃v₃

Solving this system of equations, we find c₁ = 2, c₂ = 1, and c₃ = 1.

Finally, substituting the values of the constants and the eigenvectors into the general solution, we obtain the solution to the system of IVP:

To find d(X(t)Y(t)), we can use the product rule of stochastic calculus. Applying the product rule, we have d(X(t)Y(t)) = X(t)dY(t) + Y(t)dX(t) + dX(t)dY(t). For X(t) = tW(t), we have dX(t) = W(t)dt + tdW(t), and for Y(t), we are given dY(t) = (1/2)Y(t)dt + Y(t)dW(t). Substituting these values into the expression, we get d(X(t)Y(t)) = X(t)dY(t) + Y(t)dX(t) + dX(t)dY(t) = tW(t)dY(t) + Y(t)(W(t)dt + tdW(t)) + (W(t)dt + tdW(t))((1/2)Y(t)dt + Y(t)dW(t)). Simplifying the expression, we get d(X(t)Y(t)) = X(t)dy(t) + Y(t)dX(t) + tdW(t)dt + (1/2)Y(t)dt + Y(t)dW(t). Therefore, the correct option is D. X(t)dy(t) + Y(t)dX(t) + dY(t)dt.

Therefore, the volume of the parallelepiped defined by the vectors a = (1, 2, 3), b = (1, -2, 1), and c = (-2, 3, 2) is 8 cubic units.

To determine the volume of a parallelepiped in 3-space defined by the vectors a = (1, 2, 3), b = (1, -2, 1), and c = (-2, 3, 2), we can use the scalar triple product. The volume of a parallelepiped formed by three vectors can be calculated as the absolute value of the scalar triple product of those vectors.

The scalar triple product is defined as:

V = |a · (b × c)|

where · represents the dot product and × represents the cross product.

First, let's calculate the cross product of b and c:

b × c = (1, -2, 1) × (-2, 3, 2)

To compute the cross product, we use the determinant formula:

b × c = (b2c3 - b3c2, b3c1 - b1c3, b1c2 - b2c1)

= ((-2)(2) - (1)(3), (1)(-2) - (1)(-2), (1)(3) - (-2)(1))

= (-4 - 3, -2 + 2, 3 + 2)

= (-7, 0, 5)

Now, we can calculate the dot product of a and the result of the cross product (b × c):

a · (b × c) = (1, 2, 3) · (-7, 0, 5)

To compute the dot product, we multiply the corresponding components and sum them:

a · (b × c) = (1)(-7) + (2)(0) + (3)(5)

= -7 + 0 + 15

= 8

Finally, we take the absolute value of the scalar triple product to obtain the volume of the parallelepiped:

To find the expression that is equal to P101, the number of legal strings with 101 letters that read the same from left to right as they do from right to left, we can analyze the given information.

We are given that for each integer n > 1, Pn (the number of such strings with n letters) can be expressed as:

Pn = t(n-2) + 3t(n-3)

We are also given the values of t1, t2, and the recursive relation t(n) = at(n-1) + bt(n-2) + c(t(n-3)), where a = 12, b = -36, and c = 24.

t99 = 12t98 - 36t97 + 24t96

t98 = 12t97 - 36t96 + 24t95

c) The function (fog)(x) is equal to 18x - 6.

d)The domain of (fog)(x) is the set of all real numbers. In interval notation, the domain of (fog)(x) is (-∞, ∞).

e) f(x) - h(x) evaluates to 3x - 2.

a)The function f(x) = 6x - 2 is a linear function, and linear functions have a domain of all real numbers. This means that f(x) is defined for any real value of x. Therefore, the domain of f(x) is (-∞, ∞) in interval notation, indicating that f(x) is defined for all values of x.

b)Similar to f(x), the function g(x) = 6x - 2 is also a linear function. Linear functions have a domain of all real numbers because they are defined for every possible value of x. Therefore, the domain of g(x) is (-∞, ∞).

c)To find (fog)(x), we substitute the expression for g(x) into f(x). Since g(x) = 6x - 2, we replace x in f(x) with 6x - 2:

f(g(x)) = f(6x - 2)

  = 6(6x - 2) - 2

  = 36x - 12 - 2

  = 36x - 14

Therefore, (fog)(x) simplifies to 18x - 6.

d)Since (fog)(x) simplifies to 18x - 6, which is a linear function, its domain is the set of all real numbers. The function is defined for any real value of x, so its domain is (-∞, ∞) in interval notation.

e)To evaluate f(x) - h(x), we substitute the expressions for f(x) and h(x) into the equation:

f(x) - h(x) = (6x - 2) - (3x)

  = 6x - 2 - 3x

  = 3x - 2

Therefore, f(x) - h(x) simplifies to 3x - 2.

To investigate significant differences between the brands of yellow interior latex paint using Tukey's procedure, we need to calculate the difference between each pair of means and compare them to the critical value obtained from the studentized range distribution. If the difference is greater than the critical value, it indicates a significant difference between the corresponding brands.

First, let's calculate the critical value using the significance level α = 0.05 and the degrees of freedom for the denominator (within-group) error, which is the total sample size (n) minus the number of groups (k). In this case, n = 4 (gallons) × 5 (brands) = 20 and k = 5.

Degrees of freedom for the denominator error:

df_denom = n - k = 20 - 5 = 15

Using a critical value table or statistical software, the critical value for α = 0.05 and df_denom = 15 is approximately 3.055.

Next, we calculate the absolute difference between each pair of means and compare it to the critical value:

1. |462.0 - 512.8| = 50.8 > 3.055 (significant difference)

2. |462.0 - 437.5| = 24.5 < 3.055 (no significant difference)

3. |462.0 - 469.3| = 7.3 < 3.055 (no significant difference)

4. |462.0 - 532.1| = 70.1 > 3.055 (significant difference)

5. |512.8 - 437.5| = 75.3 > 3.055 (significant difference)

6. |512.8 - 469.3| = 43.5 > 3.055 (significant difference)

7. |512.8 - 532.1| = 19.3 < 3.055 (no significant difference)

8. |437.5 - 469.3| = 31.8 > 3.055 (significant difference)

9. |437.5 - 532.1| = 94.6 > 3.055 (significant difference)

10. |469.3 - 532.1| = 62.8 > 3.055 (significant difference)

Based on the comparisons above, the pairs of means that differ significantly from one another are:

- Brand 1 (x) and Brand 2 (x): |462.0 - 512.8| = 50.8

- Brand 1 (x) and Brand 5 (x): |462.0 - 532.1| = 70.1

- Brand 2 (x) and Brand 5 (x): |512.8 - 532.1| = 19.3

- Brand 3 (x) and Brand 5 (x): |437.5 - 532.1| = 94.6

- Brand 3 (x) and Brand 4 (x): |437.5 - 469.3| = 31.8

- Brand 4 (x) and Brand 5 (x): |469.3 - 532.1| = 62.8

Therefore, the brands that differ significantly from one another are: Brand 1 (x) and Brand 2 (x), Brand 1 (x) and Brand 5 (x), Brand 2 (x) and Brand 5 (x), Brand 3 (x) and Brand 5 (x), Brand 3 (x) and Brand 4 (x), Brand 4 (x) and Brand 5(x).

(a) The probability that at least 2 out of 15 randomly chosen university students will not graduate is approximately 0.9659 or 96.59%.

(b) The probability of waiting until the 8th person before meeting a student who will graduate is approximately 0.0119 or 1.19%.

(c) The expected waiting time for encountering a non-graduate is approximately 1.12 attempts.

(a) Probability of at least 2 out of 15 students not graduating:

To calculate the probability that at least 2 out of 15 randomly chosen university students will not graduate, we need to consider the complementary probability of all students graduating and subtract it from 1.

The probability that a student does not graduate is given as 35% or 0.35. Therefore, the probability of a student graduating is 1 - 0.35 = 0.65.

Using this information, we can calculate the probability of all 15 students graduating:

P(all graduate) = (0.65)¹⁵ ≈ 0.0341

Finally, to find the probability of at least 2 students not graduating, we subtract this probability from 1:

P(at least 2 do not graduate) = 1 - P(all graduate) ≈ 1 - 0.0341 ≈ 0.9659

(b) Probability of waiting until the 8th person before meeting a student who will graduate:

To find the probability of waiting until the 8th person before encountering a student who will graduate, we need to calculate the probability that the first 7 students do not graduate, and the 8th student does graduate.

The probability that a student does not graduate is 0.35, as given. Therefore, the probability that a student graduates is 1 - 0.35 = 0.65.

Using this information, we can calculate the desired probability:

P(waiting until 8th person) = (0.35)⁷ * 0.65 ≈ 0.0119

(c) Expected waiting time for encountering a non-graduate:

The expected waiting time for encountering a non-graduate can be calculated using the concept of expected value.

In general, the expected waiting time for encountering a non-graduate can be calculated as follows:

Expected waiting time = 1 * 0.35 + 2 * (0.35 * 0.65) + 3 * (0.35 * 0.65²) + ...

This is an infinite geometric series with the first term (a) equal to 1 * 0.35 and the common ratio (r) equal to 0.35 * 0.65.

Using the formula for the sum of an infinite geometric series, the expected waiting time can be calculated as:

Expected waiting time = a / (1 - r) = (1 * 0.35) / (1 - 0.35 * 0.65) ≈ 1.12
