Tim receives a 8% commission on each house he sells. if he received a commission of $23,400 what was the value of the house he sold

$292,500  

Step-by-step explanation:

Let H = house value and let C = commission  

A 8% commission means that C = 8% of H so the equation is C = 0.08*H  

If C = $23400 then  

23400 = 0.08*H

H = 23400/0.08 = 292500  

So the value of the house is $292,500

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.
