Whenever you mutiply 2 or more terms with the same base you can add the exponents. whenever you divide 2 or more terms with the same base you can subtract the exponents.
whenever u have an exponent expression that is raised to a power you can mutiply the exponent and power.
using the basic exponent rules above simplify each expression.

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

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.
