Determine whether an equation written with one operation can be rewritten as an equivalent equation using a different operation. Choose True or False for each statement. Multiplication and division are inverse operations. Choose... The equation 3x = 12 can be rewritten as x = 12 ÷ 3. Choose... Addition and subtraction are inverse operations. Choose... The equation x + 1.793 = 2.42 can be rewritten as x – 1.793 = 2.42 – 1.793. Choose...

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.
