The probability that an individual with a positive screening test will indeed have the disease is 0.9798.

What is probability?

The probability is equal to the variety of possible outcomes. the total number of outcomes that might occur. The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

A medical study team wanted to assess a suggested diabetic screening.

When administered to a random sample of 150 diabetic individuals, the test produced 34 positive findings.

While it produced 9830 negative findings when administered to a random sample of 9850 healthy people.

Assume that 30% of the population has diabetes.

The probability that an individual with a positive screening test will indeed have the disease is 0.9798.

How to obtain probabilities using the normal distribution?

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 1050, \sigma = 195[/tex]

The proportion of scores of 1420 or higher is one subtracted by the p-value of Z when X = 1420, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (1420 - 1050)/195

Z = 1.9

Z = 1.9 has a p-value of 0.9713.

1 - 0.9713 = 0.0287 = 2.87%.

The proportion of test takers that scored 800 or lower is the p-value of  Z when X = 800, hence:

Z = (800 - 1050)/195

Z = -1.28.

Z = -1.28 has a p-value of 0.1003.

The proportion between 1500 and 1600 is the p-value of Z when X = 1600 subtracted by the p-value of Z when X = 1500, hence:

Z = (1600 - 1050)/195

Z = 2.82

Z = 2.82 has a p-value of 0.9976.

Z = (1500 - 1050)/195

Z = 2.31

Z = 2.31 has a p-value of 0.9896.

Hence:

0.9976 - 0.9896 = 0.008 = 0.8%.

The proportion above 1550 is one subtracted by the p-value of Z when X = 1550, hence:

Z = (1550 - 1050)/195

Z = 2.56

Z = 2.56 has a p-value of 0.9948.

Hence:

1 - 0.9948 = 0.0052.

Out of 200,000 students, the number is given as follows:

0.0052 x 200,000 = 1040 students.

the length of a rectangle is (2x + 3) ft. and the width is (x - 4) ft. Find the perimeter and area in terms of x.

Answers

The perimeter of the rectangle is (6x - 2)ft and the area of the rectangle is (2x^2 - 5x - 12) square ft.

What is a rectangle?

A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. Because of this, it is also known as an equiangular quadrilateral.

We are given that the length of a rectangle is (2x + 3) ft. and the width is

(x - 4) ft.

We know that perimeter of rectangle = 2(Length + Width)

So,

⇒Perimeter = 2(2x + 3 + x - 4)

⇒Perimeter = 2(3x - 1)

⇒Perimeter = (6x - 2)ft

We know that area of rectangle = Length * Width

So,

⇒Area = (2x + 3) * (x - 4)

⇒Area = 2x^2 - 8x + 3x - 12

⇒Area = (2x^2 - 5x - 12) square ft

Hence, the perimeter of the rectangle is (6x - 2)ft and the area of the rectangle is (2x^2 - 5x - 12) square ft.

help (inequalities)
What is the actual interval of existence for the solution (from part a)?

Answers

The actual interval of existence for the solution is all real numbers, including t = 0.

a. The characteristic equation for the differential equation is

2t dy/dt = 8y,

which gives us

dy/dt = 4/t y.

Separating variables, we have

dy/y = 4/t dt,

which integrates to

ln|y| = 4 ln|t| + C,

where C is an arbitrary constant of integration.

Taking the exponential of both sides, we obtain

|y| = Ce^(4ln|t|),

which gives us

y = C t^4.

Using the initial condition y(-1) = 2, we can find the value of C:

y(-1) = C(-1)^4

2 = C(-1)^4

C = -2.

So the solution to the initial value problem is

y(t) = -2 t^4.

b. The largest interval of the form a < t < b on which the existence and uniqueness theorem for first order linear differential equations guarantees the existence of a unique solution is t ≠ 0, since the coefficient of the differential equation is undefined at t = 0.

Answers

The slope of the secant line is 137.

What is the rate of change of discharges between 1994 and 1995?

The rate of change of discharges between 1994 and 1995 can be determined by taking the first derivative of the function, f'(x) = 3.3x² - 72x + 260. When x = 1994, the rate of change is -6. This means that the discharges decreased by 6 from 1994 to 1995.

The average rate of change of discharges from 1994 to 2000 can be determined by taking the average of the first derivative of the function for x = 1994 and x = 2000. When x = 1994, the first derivative is -6 and when x = 2000, the first derivative is 148. The average rate of change of discharges from 1994 to 2000 is therefore 71.

Chebyshev's inequality theorem can be used to find the probability range for an unknown distribution based on its mean and variance.

Chebyshev is named after a Russian mathematician, although the first formulation of the inequality was obtained from his colleague, Irénée-Jules Bienaymé. Chebyshev's inequality theorem was introduced without any proof in 1874, which later, in 1884,

Construct a figure illustrating the fact that the initial value problem y' = 2/7, y(0) = 0 has infinitely many different solutions. (b) For what values of b does the initial value problem y' = 2/y, y(0) = b have (i) no solution, (ii) a unique solution that is defined for all x?

Answers

(a) Verifying that y(x) = (x - c)^2 satisfies the differential equation y' = 2y:

To verify that the function y(x) = (x - c)^2 satisfies the differential equation y' = 2y, we can find the derivative y' and substitute it back into the equation:

y' = d/dx [(x - c)^2] = 2(x - c)

So, y' = 2y if and only if 2(x - c) = 2y, which can be simplified to x - c = y.

Therefore, y(x) = (x - c)^2 satisfies the differential equation y' = 2y for all x, including x = c.

(b) Values of b for which the initial value problem y' = 2/y, y(0) = b has no solution or a unique solution:

(i) No solution: If b = 0, the initial value y(0) = 0 and the denominator of the right-hand side of the differential equation y' = 2/y would be 0, making the equation undefined at that point. Therefore, the initial value problem y' = 2/y, y(0) = 0 has no solution.

(ii) Unique solution defined for all x: For all other values of b (b ≠ 0), the initial value problem y' = 2/y, y(0) = b has a unique solution that can be found using standard methods of solving initial value problems. This solution will be defined for all x.

The figure illustrating the fact that the initial value problem y' = 2/7, y(0) = 0 has infinitely many different solutions would show a family of curves that are all solutions to the differential equation y' = 2/7, with different starting values y(0) leading to different curves. This demonstrates that there are infinitely many different solutions to the initial value problem.

a.):

[tex]y=a(x-(-4))(x-3)\\y=a(x+4)(x-3)\\\\7=a(2+4)(2-3)\\7=a(6)(-1)\\7=-6a\\-7/6=a\\\\y=-7/6(x+4)(x-3)[/tex]

5. The vertex form of a quadratic equation is

[tex]y=a(x-h)^2+k[/tex], where a is the same type of number as in the intercept form and (h, k) is the vertex.

Like the intercept form of the equation, we're given everything except a and thus we can plug in what we have and solve for a:

A piecewise function f (x) is defined by f of x is equal to the piecewise function of 2 to the power of the quantity x plus 1 end quantity minus 3 for x is less than or equal to 2 and the quantity 10 over x for x is greater than 2

Part A: Based on the graph of f (x), what is the range? (5 points)

Part B: Determine the asymptotes of f (x). (5 points)

Part C: Describe the end behavior of f (x). (5 points)

Answers

Part A: The range of a function is the set of all possible outputs (y-values) for the given domain of the function. In this case, the domain of f(x) is all real numbers. We can find the range of f(x) by analyzing the two different parts of the piecewise function:

For x <= 2, f(x) = 2^(x+1) - 3. The minimum possible output for this function is y = -1 (when x = -1) and the maximum possible output is y = 3 (when x = 0).

For x > 2, f(x) = 10/x. The minimum possible output for this function is y = 0 (as x approaches infinity) and the maximum possible output is y = 10 (when x = 2)

So, the range of f(x) is [-1, 10].

Part B: The asymptotes of a function are the lines that the graph of the function approaches but never touches. In this case, the graph of f(x) has a vertical asymptote at x = 0, because the function is not defined at x=0.

Part C: The end behavior of a function is the behavior of the function as the input (x) approaches positive or negative infinity. In this case, the function f(x) = 10/x as x > 2, as x approaches positive infinity the output(y) approaches 0, and as x approaches negative infinity the output(y) does not exist. Therefore, the end behavior of f(x) is that it approaches 0 as x approaches positive infinity.

1 gallon=4.546 10 litres in gallon is approximately?​

Answers

If 1 gallon = 4.546 litres, then 10 litres in gallon is approximately 2.2 gallons.

1 gallon = 4.546 litres,

∴ 1 litre = [tex]\frac{1}{4.546}[/tex] = 0.2199 gallon

∴ 10 litres = 10 × 0.2199 = 2.199 gallons ≅ 2.2 gallons

Thus, 10 litres in gallon is approximately equal to 2.2 gallons.

The compound inequality for the graph shown above include the following:

x < -2.

x > 5.

What is a number line?

In Mathematics, a number line can be defined as a type of graph with a graduated straight line which comprises both positive and negative numerical values that are placed at equal intervals along its length.

Since the first point is at -2 and the arrow points to the left of the number line, it represents the less than (<) inequality symbol and should be written as x < -2.

Additionally, the second point is at 5 and the arrow points to the right of the number line, it represents the greater than (>) inequality symbol and should be written as x > 5.

Which expression is equivalent to (16x^4)^1/2

Answers

The expression that is equivalent to (16x^4)^1/2 is (64x^6)1/3.

What are equivalent expressions?

Equivalent expressions are expressions that accomplish the same thing even when they have distinct appearances. Two algebraic expressions that are equivalent share a similar value whenever we enter exact same thing for the variable.

Given that;

[tex](16x^4)^{\frac{1}{2}}[/tex]

[tex]=\sqrt{16x^4}[/tex]

= 4x²

From the given options, (64x^6)^1/3 verifies the identity and shows that it is equivalent to (16x^4)^1/2.

[tex](16x^4)^{\frac{1}{2}} = (64x^6)^{\frac{1}{3}}[/tex]

[tex](16x^4)^{\frac{1}{2}} = (4^3)^{\frac{1}{3}} (x^6)^{\frac{1}{3}}[/tex]

[tex]4x^2= (4) (x^6)^{\frac{1}{3}}[/tex]

[tex]4x^2=4x^2[/tex]

Therefore, we can conclude that the expression that is equivalent to (16x^4)^1/2 is (64x^6)1/3

What is the triangle's base, b?

Answers

A=1/2bh and b=2A/h so

b=2A/h =2(12cm^2)/3cm=8cm

Solution :

In order to find the base

We apply the area of a triangle formula to find the base

We know the formula to find the area of a triangle is,

[tex]A =\frac{1}{2}XbXh[/tex]

Here the area and the height is given

So the base is

[tex]12 = \frac{1}{2} X bX3[/tex]

Substituting the values we get

[tex]\frac{12X2}{3} = b[/tex]

[tex]8cm = b[/tex]

1kg/2.2lbs = X/165lbs

Answers

The answer is X=165 lbs (or) 74.84 kg.

Solution:

Given,

1kg/2.2lbs = X/165lbs,

So we get 1kg×165lbs= 2.2lbs×X,

By converting kg to lbs ∵ 1 kg= 2.2 lbs,

X=165 lbs.

∴ Hence X=165 lbs

EXPERIMENT EIGHT In Mohr's method, chloride is titrated with a silver nitrate solution. A soluble chromate salt is added as DETERMINATION OF CHLORIDE BY THE MOHR METHOD PRINCIPLE the indicator. When the precipitation of the chlorine is complete, the first excess of silver ions react with chromate to form a red precipitate of silver chromate: Ag + C AgCl(s) (Titrating reaction) (AgNO) (White) 2Ag + CO Ag-CO(S) (End-point reaction) (red) Titrant added near the equivalent point cause local excesses of silver ions that result in flashes of red colour, but the correct end point is the first permanent darkening of the yellow chromate colour. The end-point is not as sharp as might be desired. Some excess silver nitrate must be added to form enough silvery chromate to be seen over the heavy white precipitate and yellow chromate solution. This makes it necessary to determine an indicator blank, the volume of which is subtracted from the volume of silver nitrate used in titrating the sample. The concentration of chromate indicator is important. If too much chromate is added, the end-point occurs before the equivalence point; if not enough, the end-point come late (Why?). Acidity is important in the Mohr titration. In acidic solutions, part of the indicator is present as HCO, instead of CrO2; hence, more indicator is needed to form a silver chromate precipitate. About pH 8 is ideal for the titration. Sodium Carbonate will buffer the solution of about this pH. With more alkaline solutions, there is danger of precipitating some silvery carbonate of silver hydroxide. PROCEDURE Dry the NaCl for 1 hour at 100-1100C, Carefully, weight 0.25g and 0.35g samples. Dissolve each in about 100cm' of water. Add a pinch of calcium carbonate or sodium hydrogen carbonate, making further additions if necessary, until effervescences ceases. Then introduce 1 to 2 cm of 5% potassium chronmate, and titrate with standard silver nitrate solution to the first permanent appearance of a buff colour due to silver chromate. Determine an indicator blank by suspending the small quantity of calcium carbonate in about 100cm' of water containing 1 to 2cm of 5% potassium chronmate. Use the colour developed in this determination as a standard for judgement of the end-point in the actual titration. What is the systematic name of the following compound?
