Candidates are applying for an elite college. From prior statistics we know that white students have an acceptance rate of 24% while Asian students have an acceptance rate of only 17%. A random sample of 100 White students and 100 Asian students were selected. Let X be the number of White applicants (out of the 100) who are accepted. Let Y be the number of Asian applicants (out of the 100) who are accepted.

Question 1 of 4 Which of the following is true regarding the random variables X and Y?

Neither X nor Y can be well-approximated by a normal random variable.

Only Y can be well-approximated by a normal random variable.

Both X and Y can be well-approximated by normal random variables.

Only X can be well-approximated by a normal random variable.

The remaining questions refer to the following information: Suppose the scores on an exam are normally distributed with a mean μ = 75 points, and standard deviation σ = 10 points.

Question 2 of 4 Suppose that the top 4% of the exams will be given an A+. In order to be given an A+, an exam must earn at least what score? 65 , 68 , 85 , 92.5

Question 3 of 4 What is the exam score for an exam whose z-score is 1.25? 60 , 70 , .1056 , 87.5 , .8944

Question 4 of 4 The instructor wanted to "pass" anyone who scored above 69. What proportion of exams will have passing scores? 0.6 , -0.6 , .7257 , .2743

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

you have to put the graph on here with the question

step-by-step explanation:

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
