There are 3 counselors for every 45 students enrolled in a camp. what is the maximum number of students allowed if there are 10 counselors? #hw

Make it a ratio.

3:45

Then, you make another ratio.

10:x

You want to find the x so that the first ratio is still valid.

3 multiplied by what equals 10? It is not a pretty number so put it in fraction form, 10/3.

Multiply 45 by 10/3.

Therefore, the maximum number of students allowed is 150.

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.
