Approximately 10.3% of American high school students drop out of school before graduation. Choose 11 students entering high school at random. Find the probabilities. Round the answer to four decimal places. a. No more than 2 dropout

0.9039.

Step-by-step explanation:

We have been given that  approximately 10.3% of American high school students drop out of school before graduation. Choose 11 students entering high school at random. We are asked to find the probability of no more than 2 dropout.

We will use Bernoulli's trials to solve our given problem as:

For no more than 2 dropouts, we need to find dropout of 1 student and 2 students as:

Therefore, the probability of no more than 2 dropout is 0.9039.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
