<h3>What is a median?</h3>

A median can be defined as the <u>middle number</u> (center) of a sorted data set, which is when the data set is arranged from the least to greatest (ascending order) or greatest to least (descending order).

<u>For the </u><u>girls</u><u>:</u>

  • Median = 50.

<u>For the </u><u>boys</u><u>:</u>

  • Median = 33.

b. 8%

c. 135%

4 dimes is 40 cents out of 100 cents, so that's 40%. 1 nickel is 5 cents and 3 pennies are 3 cents, which adds up to 8 cents out of 100 potential cents, so 8%. 5 quarters is 1.25 dollars and a dime is 10 cents, together it makes 1.35 dollars. Multiply that by 100 since there are 100 cents in a dollar and you get 135%
