Suppose 22 music learners who took the 2018 Royal Conservatory music exam are selected at random, what model would you use to find the probability that exactly 2 of the music learners will be asked to repeat the music level

Bin(22, 0.15)

Step-by-step explanation:

Given Data:

percentage of learners asked to repeat = 15% (bottom 15%)

no of learners asked to repeat = 2

total learners = 22

Model to be used to find probability of exactly 2 of music learners that will be asked to repeat the music level = Bin ( 22, 0.15 )

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
