For the following linear equations, determine which inverse operation allows you to determine he solution of he equation. In you final answer, also include the solution to each equation. 1. n/5= -0.3
2. -2n= 4 1/3

N = -2 1/6

Step-by-step explanation:

1. n/5 = -0.3

5*        5*

n = -1.5

2.   -2n= 4 1/3

-2n = 13/3

-2n/ -3 = (13/3)/-2

n = -13/6

n = -2 1/6

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.
