Select the correct answer.
what is the product of

29

Step-by-step explanation:

I'm going to write both of this as improper fractions.

That is the mixed fraction can be written as the improper equivalent fraction of assuming is positive.

So we are going to write as .

Simplifying that gives us .

Now for .

Now we are ready to find the product which just means multiply:

To multiply fractions you just multiply straight across on top and straight across on bottom unless you see a common factor on and bottom to cancel (and I do; I see 10)

Negative times negative is positive.

Anyways time to write 87/3 as a mixed fraction.

How many 3's are in 87?  29  with no remainder

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.
