Answer:
Complete the following statements. In general, 50% of the values in a data set lie at or below the median. 75% of the values in a data set lie at or below the third quartile (Q3). If a sample consists of 500 test scores, of them 0.5*500 = 250 would be at or below the median. If a sample consists of 500 test scores, of them 0.75*500 = 375 would be at or above the first quartile (Q1).
Step-by-step explanation:
The median separates the upper half from the lower half of a set. So 50% of the values in a data set lie at or below the median, and 50% lie at or above the median.
The first quartile(Q1) separates the lower 25% from the upper 75% of a set. So 25% of the values in a data set lie at or below the first quartile, and 75% of the values in a data set lie at or above the first quartile.
The third quartile(Q3) separates the lower 75% from the upper 25% of a set. So 75% of the values in a data set lie at or below the third quartile, and 25% of the values in a data set lie at or the third quartile.
The answer is:

Circumference of a circle is pi x diameter (full length of the circle)
you have the radius which is half, so youd need to double it go geth the diameter.
24x2=48
and then 3.14x48=150.72
Answer:
$52
Step-by-step explanation:
3 books → $13
1 book → $13/3
12 books → $13/3 x 12 = $52
She walked 7 miles. If it takes her one hour to walk four miles, then it will take 45 minutes to walk 3 miles.
The formula for area of a cone is A=πr(r+√h²+r²). The radius is half the diameter, so 22.5.
Plug our numbers into the formula.
A=π22.5(22.5+√96²+22.5²)
the answer is 8560.16
