Simplify 5 to the 5th over 5 to the 8th.

1 over 5 to the 3rd power
5^3
1 over 25
1 over 5 to the negative 3rd

Hey, I'm so sorry for the delay

I hope this helps...

5^5 = 3125

5^8 = 390625

5^5/5^8 = 0.008

which is: A.) 1/5^3

35-60 students are taking math.

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.
