F.)

Experimental Design.

Step-by-step explanation:

The Independent variable are those variables which causes a change in the measured or dependent variable.

The dependent t variable is the measured variable whose change is triggered by the independent variable.

Categorical Variables are non-numeric labels while the quantitative variables are numeric labels.

Experimental designs usually divides subjects into two or more treatment groups whrebt the effects of applied treatment is observed across the different groups.

Answer:

Her monthly payment is approximately $4,611.65

Step-by-step explanation:

The monthly payment on the loan is given by the following formula;

[tex]A = P \cdot \dfrac{r\cdot (1 + r)^n}{(1 + r)^n - 1}[/tex]

A = The monthly payment

P = The principal amount = $423,000

r = 5.65%

The number of years = 10 years

[tex]A = 423,000 \cdot \dfrac{\dfrac{0.0565}{12} \cdot \left (1 + \dfrac{0.0565}{12} \right )^{180}}{\left (1 + \dfrac{0.0565}{12} \right )^{180} - 1} \approx 4611.65[/tex]

Her monthly payment, A ≈ $4,611.65

Answer:

Step-by-step explanation:

You should add the weights of each kitten and then divide by the number of kittens. Ex. There are 5 kittens weighing 2, 1, 3, 2, and 2. So you would add those to get 10 and divide by the number of kittens which is 5 to get an average of 2.

So in this case you would first add the weight of the kittens

Then divide that by the number of kittens

Then the quotient would be the average of the weight of the kittens in the shelter.

Answer:

The first answer one is true

The function that best models for the data is y = -200 (x-4)^2 + 800.

A function is a mathematical expression that describes how factors are related. In this case, how the price is related to the profit.

The best way to determine this is to solve the expression and verify if the answer is correct.

For example, we know that at 4 (x) dollars, the daily profit is $800 (y). Let's now the different options:

A.

B.

C.

D.

This means B and D are possible options, however, when verified with other results such as $6 the correct one is option D.

The quadratic equation is given by y = -200x² + 1600x - 2400.

The standard form of the quadratic equation is:

y = ax² + bx + c

Where a,b,c are constants.

Let y represent the daily profit for x bread price.

At point (2, 0):

0 = a(2)² + b(2) + c

4a + 2b + c = 0    (1)

At point (4, 800):

800 = a(4)² + b(4) + c

16a + 4b + c = 800    (2)

At point (6, 0):

0 = a(6)² + b(6) + c

36a + 6b + c = 0    (3)

From all the equations:

a = -200, b = 1600, c = -2400

The quadratic equation is given by y = -200x² + 1600x - 2400.

Answer:

Table A.

Step-by-step explanation:

$139.50 / 6 hours = $23.25 an hour

1 hour of work = $23.25 earned

(now add $23.25 for the next hour of work)

2 hours of work = $46.50 earned

(now add $23.25 for the next hour of work)

3 hours of work = $69.75

(now add $23.25 for the next hour of work)

4 hours of work = $93 earned

(now add $23.25 for the next hour of work)

5 hours of work = $116.25 earned

(now add $23.25 for the next hour of work)

6 hours of work = $139.50 earned

(now add $23.25 for the next hour of work)

7 hours of work = $162.75 earned

(now add $23.25 for the next hour of work)

8 hours of work = $186 earned

(now add $23.25 for the next hour of work)

9 hours of work = $209.25

(now add $23.25 for the next hour of work)

10 hours of work = $232.50

Answer:

y = 3/4x -2

Step-by-step explanation:

Points on the graph: (4, 1) and (0, -2)

Slope:

m=(y2-y1)/(x2-x1)

m= (-2-1)/0-4)

m=(-3)/(-4)

m = 3/4

Point-slope:

y - y1 = m(x - x1)

y - 1 = 3/4(x - 4)

y - 1 = 3/4x - 3

y = 3/4x -2

Answer:

a) 0.7639 = 76.39% probability that at least 3 passengers will have been stopped due to change in their pockets.

b) 0 is less than 2.5 standard deviations from the mean, so it would not be unusual.

Step-by-step explanation:

For each passenger, there are only two possible outcomes. Either they will have been stopped due to a change in the pocket, or not. Passengers are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

A measure is considered unusual if it is more than 2.5 standard deviations of the mean.

25% chance that the cause is change in the passenger's pocket.

This means that [tex]p = 0.25[/tex]

During a given hour, 15 passengers are stopped because of a signal from the metal detector.

This means that [tex]n = 15[/tex]

a) Find the probability that at least 3 passengers will have been stopped due to change in their pockets.

This is

[tex]P(X \geq 3) = 1 - P(X < 3)[/tex]

In which

[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{15,0}.(0.25)^{0}.(0.75)^{15} = 0.0134[/tex]

[tex]P(X = 1) = C_{15,1}.(0.25)^{1}.(0.75)^{14} = 0.0668[/tex]

[tex]P(X = 2) = C_{15,2}.(0.25)^{2}.(0.75)^{13} = 0.1559[/tex]

[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0134 + 0.0668 + 0.1559 = 0.2361[/tex]

[tex]P(X \geq 3) = 1 - P(X < 3) = 1 - 0.2361 = 0.7639[/tex]

0.7639 = 76.39% probability that at least 3 passengers will have been stopped due to change in their pockets.

b) If 15 passengers are stopped by the detector, would it be unusual for none of these to have been stopped due to change in the pocket

First we find the mean and the standard deviation:

[tex]E(X) = np = 15*0.25 = 3.75[/tex]

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{15*0.25*0.75} = 1.68[/tex]

3.75 - 2.5*1.68 = -0.45

0 is less than 2.5 standard deviations from the mean, so it would not be unusual.
