If a random sample of size n = 43 is drawn, find μx, σ x and p(28 ≤ x ≤ 30). (round σx to two decimal places and the probability to four decimal places.)

hope this .

step-by-step explanation:

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be

the square root of 16 is 4.

4*4 = 16
