How to solve this problem 4 = 4x

4 = 4x                  (original equation)

4/4 = 4x/4          (divide both sides by 4)

1 = x                    (simplify)

Make sure that you're doing the same things to each value on BOTH sides. This keeps the equation true. Once you do that, you should get that x is equal to 1.

Clue:On the multiplication table 4×?=4

it’s the first one your welcome

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.
