Question

The two-way relative frequency table shows the relative frequencies of 9- and 10-year-olds who prefer Superhero A or B.

Answer 1

The answer is 37.5% because to change a decimal to a percent, you move the decimal over 2 places to the right, and since the decimal is behind zero, it ends up between 7 and 5.

hopefully this helped you.

Answer 2

Answer:

37.5%

Step-by-step explanation:

The question asks for "the percent of 9-year olds who prefer Superhero A"

[Note: Since the table is given in terms of decimal, we will do the problem in decimal and later change to percentage]

• How many total 9-year olds are there?

Add the 9-year olds row. We have:

$0.375+0.625=1$

• Now, how many of those 9-year olds like Superhero A?

Look at the cell under Superhero A & beside 9-year old. We see that it is $0.375$

So we would divide this by total, to get,

$\frac{0.375}{1}=0.375$

To convert decimal into percentage, we multiply the decimal with 100 and then tag along the "%" sign. Hence, we have:

$0.375*100=37.5$%
