4/5G + 42 = 2.8G + 18
Plz solve with an explanation

12

Step-by-step explanation:

Simplify  \frac{4}{5}G

5

4

G  to  \frac{4G}{5}

5

4G

.

\frac{4G}{5}+42=2.8G+18

5

4G

+42=2.8G+18

Multiply both sides by 5.

4g + 210 = 14g + 90

Simplify  

 14G + 90 - 4G to 10G + 90

Subtract 90 from both sides.

210-90=10G210−90=10G

Simplify  210-90210−90  to  120120.

120=10G120=10G

Divide both sides by 1010.

\frac{120}{10}=G

10

120

=G

Simplify  \frac{120}{10}

10

120

  to  1212.

12=G12=G

Switch sides.

G=12G=12

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.
