Answer:

The y-value will be -0.75.

Step-by-step explanation:

If the rate of change is 0.25, then every time the x-value goes up by 1, 0.25 will be added to our y-value. For example, if we were to go from the x-value of 12 to 13, then our y-value would be -1.75.

If our x-value is to be 19, then we would subtract 0.25 from the y-value (0) of the x-value (20, since it is one number below.)

Therefore, 0 - 0.25 would be -0.75.

Answer: 0.0123

Step-by-step explanation:

Given : Customers leaving a subway station can exit through any one of three gates.

The probability of selecting any particular gate = $\dfrac{1}{3}$

Sample size : n= 4

Using binomial distribution,

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success inn x trials , n is the number of trails and p is the probability of getting success in each trial.

Then , the probability that among a sample of 4 customers, they all exit through the same gate.

$P(4)=^4C_4(\dfrac{1}{3})^4(\dfrac{2}{3})^{0}=(1)(\dfrac{1}{3})^4=0.0123456790123\approx0.0123$

Hence, the probability that among a sample of 4 customers, they all exit through the same gate = 0.0123

You would have to calculate the percent first.
Add the total number of students
3420+4680= 8100 students TOTAL

Then you would divide the amount of students by the total

3420 part time/8100 students total = .42 or 42%

4680 full time/8100 total = .58 or 58%

Then you multiply the percentages by 90

(90)(.58)= 52.2

(90)(.42)= 37.8

Rounded

52 full time and 38 part time students
