Max bought two deli sandwich rolls measuring 18 inches and 30 inches. He want them to be cut in equal sections that are as long as possible. Into what lengths should the rolls be cut?

 Into 6 inches

Step-by-step explanation:

In this situation, the problem will be to find the greatest common factor of 18 and 30 because that is how you could divide them.

The GCF of 18 is   1,2,3,6,9, and 18

The GCF of 30  is 1,2,3,5,6,10,15 and 30  

The greatest possible factor of both numbers is 6

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

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.
