Answer:

A.) The Independent variable is media consumption. ;

B.)

1.) Abstinence from media consumption

11.) Continued consumption of media

C.)

Categorical Variable ;

D.)

Dependent variable is Aggressive behavior ;

E.)

The dependent variable is a continous numerical variable

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:

O y=x^2-10

Step-by-step explanation:

x^2 = parabola

the rest are just linear equations

Answer:

the angle of inclination of the hill is 46.56°

Step-by-step explanation:

  Given the data in the question;

Just as illustrated in the diagram below

so to find the angle of inclination of the hill;

sinA/30 = sinB/125

since angle BAC  is 8°

we substitute

sin8°/30 = sinB/125

sinB = ( sin8°/30 ) × 125

B = sin⁻¹ ( ( sin8°/30 ) × 125 )

B = sin⁻¹ ( 0.004639 × 125 )

B =  35.44°

so since the some of a the angles of a triangle is 180;

A + B + C = 180

8° + 35.44° + C = 180

C = 180 - ( 8° + 35.44° )

C = 136.56°  

Hence, Angle of inclination x will be;

x = 136.56° - 90°

x = 46.56°

Therefore, the angle of inclination of the hill is 46.56°

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:

x < -1

Step-by-step explanation:

Let the unknown number be x

nine more than sum of eight times a number and seventeen, is expressed as;

9 >  8x + 17

Subtract 17 from both sides

9 - 17 > 8x+17-17

-8 > 8x

8x < -8

Divide both sides by 8

8x/8 < -8/8

x < -1

Hence the quotient is x < -1

Answer:  3

Step-by-step explanation: double the 5 and the 4(to have the same denominator as the 8)

Answer:

a.) 3x+2y=34 is the equation. 2 pairs could be 10,2 and 8,5.

b.) .5x+2y=14

c.) 8,5

Step-by-step explanation:

because both 8 and 5 work in both equations 3(8)+2(5)=34

.5(8)+2(5)=14

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.
