Step-by-step explanation:

To find the average speed of Henry over the whole race, we need to calculate the total distance he covered and the total time taken.

Distance covered in the first 160 m = 160 m

Distance covered in the remaining 300 m = 300 m

Total distance covered = 160 m + 300 m = 460 m

Time taken to cover the first 160 m = distance ÷ speed = 160 m ÷ 4 m/s = 40 s

Time taken to cover the remaining 300 m = 120 s

Total time taken = 40 s + 120 s = 160 s

Average speed = total distance ÷ total time taken = 460 m ÷ 160 s = 2.875 m/s

Therefore, Henry's average speed over the whole race is 2.9 m/s (rounded to 1 decimal place).

28.From the graph you can see that the height i.e f(x) was only increasing from 200 to 300 of x and 100 to 150 of f(x) and then continue to decrease. therefore we can then say f(x) is increasing when x is greater than or equal to 200 and when x is less than or equal to 300 i.e option C.

29. at x=500 f(x)=0

therefore at x= 500 f(x) was at it minimum

The classroom had 24 glue bottles.

We have,

If the ratio of glue sticks to glue bottles is 7 : 4, we can express this as 7/4.

We can set up a proportion to solve for the number of glue bottles:

7/4 = 42/x

where x is the number of glue bottles. To solve for x, we can cross-multiply:

7x = 4 x 42

7x = 168

x = 24

Therefore,

The probability of exactly two foreclosures is 0.09.

If one loan out of every 136 loans is foreclosed, the probability of a loan being foreclosed is 1/136. Therefore, the probability of a loan not being foreclosed is 135/136.

Since the bank approved 300 loans last month, the number of loans that can be foreclosed ranges from 0 to 300. We can use the binomial probability formula to calculate the probability of exactly 2 foreclosures in 300 loans:

P(X = 2) = (300 choose 2) * (1/136)^2 * (135/136)^298

Using a calculator, we can evaluate this expression to get:

P(X = 2) ≈ 0.091

Therefore, the probability of exactly two foreclosures is 0.09 (rounded to two decimal places).

Answer:

192

Step-by-step explanation:

24 *8

there are 8 lots of 30 in 4mins

Answer: I'm pretty sure it's 192

Step-by-step explanation: Every minute, 48 jars are filled (cause 24 x 2 = 48) . I just did 48 x 4.

The value of a5 is 8.

Given that,

a₁ = 4

aₙ = aₙ₋₁ + 1

So, we can find the second term a₂ using the equation of nth term,

a₂ = a₍₂₋₁₎ + 1

a₂ = a₁ + 1

Applying the value of a₁,

a₂ = 4 + 1

a₂ = 5

So, finding the value of a₃,

a₃ = a₍₃₋₁₎ + 1

a₃ = a₂ + 1

a₃ = 5 + 1

a₃ = 6

So, the value of a₄ will be,

a₄ = a₃ + 1 = 6 + 1

a₄ = 7

Therefore,

a₅ = a₄ + 1 = 7 + 1

Answer:

Step-by-step explanation:

by writing the formula of tan(30°), you'll get the answer.

Let's write it :

tan(x)=[tex]\frac{opposite}{adjacent\\}[/tex]

we have a 30° angle so x=30° :

tan(30°)=[tex]\frac{AB}{AC} = \frac{AB}{6} =\frac{1}{\sqrt{3} }[/tex]

⇒ √3 * AB = 6 ⇒ AB= [tex]\frac{6}{\sqrt{3} }[/tex]≅ 3.46

Now we can use the formula for cos (theta) to find the angle of view:
cos(theta) = adjacent/hypotenuse = 20/28.28
theta = cos^-1(20/28.28) = 45 degrees
So the angle of view of the sniper is 45 degrees.

To find the angle of view for the sniper on top of a building, we can use the trigonometric functions you provided. In this case, we know the height of the building (20 meters) and the horizontal distance (also 20 meters).

Let's denote the height as 'y' and the horizontal distance as 'x'. Given the information, y = 20 meters and x = 20 meters.

We can use the tangent function (tan theta) to find the angle:

Tan theta = y/x

Tan theta = 20/20 = 1

Now, we need to find the angle (theta) by taking the inverse tangent (arctan) of the result:

theta = arctan(1)

Using a calculator or conversion table, we find that:
cos(theta) = adjacent/hypotenuse = 20/28.28
theta = cos^-1(20/28.28) = 45 degrees
theta ≈ 45°

So, the angle of view for the sniper on top of the 20-meter high building with a 20-meter slope is approximately 45 degrees.

Answer:

  5

Step-by-step explanation:

You want the length of the line segment between (-2, 2) and (2, -1).

The relation between the side lengths of a right triangle is given by the Pythagorean theorem. It tells you ...

  c² = a² +b²

where c is the hypotenuse of the triangle, and 'a' and 'b' are the legs.

When you plot the points on a grid, you can identify the vertical and horizontal distances between them by counting grid squares, or by finding the difference of coordinates:

  AB = B -A = (2, -1) -(-2, 2) = (2 +2, -2 -2) = (4, -3)

The point on the right is 4 horizontal units and 3 vertical units from the point on the left.

The above relation tells us the segment length is ...

  c² = 4² +3² = 16 +9 = 25

  c = √25 = 5

The length of the line segment is 5 units.

Additional comment

The integer triple of segment lengths that form a right triangle is called a "Pythagorean triple." The one relevant to this problem is {3, 4, 5}. Others often seen in algebra, trig, and geometry problems are ...

  {5, 12, 13}, {7, 24, 25}, {8, 15, 17}, {9, 40, 41}

and multiples of these. If you become familiar with these triples, you can often write down the answer to a question like this simply by recognizing the dimensions involved.

a. To calculate velocity, we need to take the derivative of the position function, r(t). So, the formula for velocity is v(t) = r'(t) = [sqrt(2)(e^t - e^-t) + sqrt(2)t(e^t + e^-t)]a.

b. To calculate acceleration, we need to take the second derivative of the position function, r(t). So, the formula for acceleration is a(t) = r''(t) = [sqrt(2)(e^t + e^-t) + sqrt(2)t(e^t - e^-t) + 2sqrt(2)t(e^t + e^-t)]a.

c. To calculate distance, we need to integrate the velocity function, v(t), over a certain time interval. So, the formula for distance is d(t1, t2) = ∫[t1, t2] v(t) dt = ∫[t1, t2] [sqrt(2)(e^t - e^-t) + sqrt(2)t(e^t + e^-t)]a dt.

d. To calculate position, we need to integrate the acceleration function, a(t), twice over a certain time interval. So, the formula for position is r(t1, t2) = ∫[t1, t2] ∫[t1, t] a(s) ds dt + r(t1), where r(t1) is the initial position at time t1.


a. Velocity (v) can be calculated using the derivative of the position function r(t). In this case, v(t) = dr(t)/dt.

b. Acceleration (a) can be calculated using the derivative of the velocity function v(t). So, a(t) = dv(t)/dt.

c. Distance (d) can be calculated by finding the definite integral of the velocity function v(t) with respect to time over a specific interval. In other words, d = ∫|v(t)|dt, where the integration limits correspond to the interval of time you're interested in.

d. Position (r) is given by the function r(t) = sqrt(2)t * e^t * e^(-t), which represents the position of the object at any given time t.

The size of the U.S. budget deficit in 2010 has expanded dramatically since 2007. The correct option is Option A.

The statement indicates that the U.S. budget deficit in 2010 was significantly higher compared to the historical average since 1950.

It states that the deficit-to-GDP ratio in 2010 was 10 percent, which is much higher than the average of around 2 percent that has been observed since 1950.

This information suggests that the size of the U.S. budget deficit has expanded dramatically since 2007. The mention of the deficit-to-GDP ratio being well above the historical average implies a significant increase in the deficit relative to the size of the economy.

The answer rules out options B, C, and D, as they do not accurately describe the situation presented.

Option B states that the deficit has not changed significantly since 1950, which is contradicted by the information provided.

Option C states that the deficit has constantly expanded since 1950, which is not supported by the historical average being around 2 percent.

Option D mentions slight increases until 1983 and recent decreases, which is inconsistent with the information about a dramatic expansion since 2007.

Standard deviation is a measure of the spread or dispersion of a set of data. It is a statistical value that tells us how much the individual data points deviate from the mean (average) of the data set. T

To determine the conclusion at the 10% significance level for the given hypotheses:

H0: μ = 30

HA: μ ≠ 30

We need to perform a two-tailed t-test since the alternative hypothesis is a two-sided inequality (μ ≠ 30). We have a sample of n=7 and we don't know the population standard deviation, so we will use a t-distribution with n-1=6 degrees of freedom.

The test statistic is calculated as:

t = (x(bar) - μ) / (s / √n)

where x(bar) is the sample mean, μ is the hypothesized population mean under the null hypothesis (30), s is the sample standard deviation, and n is the sample size.

Using the sample data, we have:

x(bar) = (33 + 26 + 29 + 35 + 31 + 35 + 31) / 7 = 31.14

s = sqrt((1/6) * ((33-31.14)^2 + (26-31.14)^2 + (29-31.14)^2 + (35-31.14)^2 + (31-31.14)^2 + (35-31.14)^2 + (31-31.14)^2)) = 2.769

Plugging these values into the formula, we get:

t = (31.14 - 30) / (2.769 / sqrt(7)) = 1.118

Using a t-distribution table with 6 degrees of freedom and a significance level of 0.10, we find that the two-tailed p-value is approximately 0.307. Since the p-value is greater than α = 0.10, we fail to reject the null hypothesis.

Therefore, the conclusion is:

c) Do not reject H0 since the p-value is greater than α.

Interpreting the results at the 10% significance level:

b) We cannot conclude that the population mean differs from 30.

Note that we only fail to reject the null hypothesis, we do not accept it or prove it. We just do not have enough evidence to reject it at the given significance level.

Therefore, the dot product of u and v is √(102251).

To compute u · v, we first need to find the magnitude of u using the formula ||u|| = √(a^2 + b^2 + c^2) where a, b, and c are the coefficients of i, j, and k respectively. In this case, ||u|| = √(6^2 + (-319)^2 + 22^2) = 321. We can then find v by dividing u by its magnitude, giving us v = (√6/321)i - (319/321)j + (22/321)k. Finally, we can calculate u · v by multiplying the corresponding coefficients and adding them up, giving us u · v = (√6/321)(√6) + (-319/321)(-319) + (22/321)(22) = 1.
First, let's find the magnitude ||u||:
||u|| = √((√6)^2 + (-319)^2 + (22)^2) = √(6 + 101761 + 484) = √(102251)
Now, calculate v:
v = u / ||u|| = (√6 i - 319j + 22k) / √(102251)
To compute the dot product u · v:
u · v = (√6 * (√6/√102251)) + (-319 * (-319/√102251)) + (22 * (22/√102251))
u · v = (6/√102251) + (101761/√102251) + (484/√102251)
u · v = (102251/√102251)
Since the dot product of a vector with itself is the square of its magnitude, and we have u · v = ||u||^2/||u||:

To test the validity of a multiple regression model and the null hypothesis that the regression slope coefficients are all zero, we use the F-test. Therefore, the correct answer is option c.

1. The F-test is specifically designed to test the overall significance of a multiple regression model. It examines whether there is a significant linear relationship between the predictor variables and the response variable in the model. In the context of the null hypothesis, the F-test checks if all the regression slope coefficients are simultaneously equal to zero, indicating no significant relationship between the predictors and the response variable.

2. On the other hand, the t-test and z-test are used for testing individual regression coefficients in simple regression models or when we have prior knowledge about the standard deviation of the coefficients. They are not suitable for testing the overall significance of multiple regression models, as they do not take into account the joint effect of multiple predictors.

The integral of G(x, y, z) = z over the cylindrical surface  [tex]y^{2}[/tex] + [tex]z^{2}[/tex] = 4, z ≥ 0, 1 ≤ x ≤ 3 is (104π/3).

To integrate the function G(x, y, z) = z over the cylindrical surface y [tex]y^{2}[/tex] + [tex]z^{2}[/tex] = 4, z ≥ 0, 1 ≤ x ≤ 3, we need to express the surface as a parameterized form.

Let's parameterize the cylindrical surface by using cylindrical coordinates:

x = x

y = 2cosθ

z = 2sinθ

Here, x ranges from 1 to 3, and θ ranges from 0 to 2π since we want the upper half of the cylindrical surface where z ≥ 0.

The integral can be written as:

∫∫∫ G(x, y, z) dV

where dV is the volume element in cylindrical coordinates, given by dx dy dz = r dr dθ dz.

Now, let's calculate the integral:

∫∫∫ G(x, y, z) dV

= ∫(1 to 3) ∫(0 to 2π) ∫(0 to 2) (z) (r dz dr dθ)

We can simplify the integral:

∫(1 to 3) ∫(0 to 2π) ∫(0 to 2) (z) (r dz dr dθ)

= ∫(1 to 3) ∫(0 to 2π) [[tex]r^{2}[/tex]/2] (0 to 2) dθ dr

= ∫(1 to 3) ∫(0 to 2π) (2[tex]r^{2}[/tex]) dθ dr

= ∫(1 to 3) (2[tex]r^{2}[/tex]) (2π) dr

= 4π ∫(1 to 3) [tex]r^{2}[/tex] dr

Evaluating the integral:

4π [[tex]r^{3}[/tex]/3] (1 to 3)

= 4π [([tex]3^{3}[/tex]/3) - ([tex]1^{3}[/tex]/3)]

= 4π [27/3 - 1/3]

= 4π (26/3)

= (104π/3)

Therefore, the integral of G(x, y, z) = z over the cylindrical surface  [tex]y^{2}[/tex] + [tex]z^{2}[/tex] = 4, z ≥ 0, 1 ≤ x ≤ 3 is (104π/3).
