Mondo correctly finds the closest benchmarks for three numbers. Three and StartFraction 6 over 25 EndFraction is closest to the benchmark 3

3.8 is closest to the benchmark 4

Three and four-ninths is closest to the benchmark Three and one-half

Which shows the numbers Three and StartFraction 6 over 25 EndFraction, 3.8, and Three and four-ninths in order from greatest to least?

Three and StartFraction 6 over 25 EndFraction, Three and four-ninths, 3.8

Three and StartFraction 6 over 25 EndFraction, 3.8, Three and four-ninths

3.8, , Three and StartFraction 6 over 25 EndFraction

3.8, Three and StartFraction 6 over 25 EndFraction,

From greatest to least, the order is:

Step-by-step explanation:

Given

Required

Order from greatest to least

From the given parameters, we have:

This implies that:

--- we know this from the nearest benchmark

Convert to decimal

By comparison;

Hence, the list is:

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.
