Alocal community college determines the probability that a student will reenroll for a second year is 0.91. a representative surbeys 100 random first year students and asks them if they will be enrolling for the next year. what is the probability that exactly 91 of them wil enroll?

The probability is 0.1381, or about 13.8%

Step-by-step explanation:

The probability of a count k out of n with a known event probability p is described by the binomial distribution:

We are given n=100, p=0.91 and are asking for the probability of seeing exactly k=91 positive events (enrollment), so:

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
