Step-by-step explanation:

this ratio so $11:30you add the ratio so that is 41

so three more than three times so that is 3^3 that r

so the 3^3 means 3×3×3×3 that is 81 so 81×41 will give you your answer that is 3,321

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.
