Represent the following expressions as a power of the number a (a≠0): PLEASE ANSWER ALL OF THEM ILL AWARD 50 BRAINLIST FOR SOMEONE WHO DOES ALL OF THEM AND THEY ARE CORRECT( · means times, ^ means exponent, / means fraction ) a. (a^3)^-2

b. (a^-1 · a^-2)^-3

c. ((a^2)^-2)^2

e. (a/a^2)^-2

f. (a^2 · a^2 · a^2)^3

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

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.
