Private nonprofit four-year colleges charge, on average, $27,334 per year in tuition and fees. The standard deviation is $7,023. Assume the distribution is normal. Let X be the cost for a randomly selected college. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X ~ N(27334,7023)

b. Find the probability that a randomly selected Private nonprofit four-year college will cost less than 24,512 per year.

c. Find the 67th percentile for this distribution. $ (Round to the nearest dollar.)

my answer is$ 12

step-by-step explanation:

because 15 -2=12

i believe the answer is the polygon, heptagon.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

4+4+2x

or

2x+8
