You are making summer move plans and you are working with the following constraints: It costs $8 to go to the movies at night with student ID. It cost $5 to go to the matinee with a student ID. You want to go to at least as many night shows as matinees. You want to spend at most $42. What is the greatest number of movies that you can see? How many at night and how many matinees?

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
