Translate the sentence into an inequality.
The sum of 3 and c is less than -29.

3+c < -29 or c+3 < -29 because of communitive property

Step-by-step explanation:

First, the sum means addition, you could write 3+c or c+3 because addition is communitive property.

Then the sum is less than -29 so we need to use the less than symbol which is this symbol: <  

Now write the inequality! 3+c < -29

3 + c < -29

Step-by-step explanation:

3 + c < -29 from "The sum of 3 and c is less than -29."

3 + c < -29 from "The sum of 3 and c is less than -29."

3 + c < -29 from "The sum of 3 and c is less than -29."

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.
