Answer:

Step-by-step explanation:

a.

y=0.75x

y-y1=(y2-y1)/(x2-x1)×(x-x1)

y-3=(6-3)/(8-4) (x-4)

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

y-3=3/4 x-3

y=3/4 x-3+3

y=3/4 x

if y=f(x)

f(x)=0.75x

c.

f(12)=0.75×12=9$

a. Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are

b. Theoretical Probability. Experimental Probability.

Use theoretical probability by counting the favorable outcomes and put that in a fraction above all possible outcomes.

Use experimental probability by comparing the number of times the event occurs to the total number of trials.

Step-by-step explanation:

I don't really know what to explain. :v

horizontal asymptote: y = 10,350; no vertical asymptotes
2015: 10,084
no information on Exercise 5

Step-by-step explanation:

<h3>a)</h3>

The graph is attached

__

<h3>b)</h3>

__

<h3>c)</h3>

The graph does not cross y=0. It has a minimum of about 7392.

__

<h3>d)</h3>

The denominator is never zero, so there are no vertical asymptotes. The horizontal asymptote is the ratio of the x^2 coefficients, 414/0.04 = 10,350.

__

<h3>e)</h3>

The value of the function for x=15 is 10,084. The number of women in the Marines in 2015 is modeled as 10,084.
