Sherelle and Venita find two bags of coins in their grandmother's attic. Each girl selects a bag, takes a random
sample of 20 coins from that bag, and lists the dates of those coins as the number of years since 1900. Here are
the results.
Sherelle: 72, 56, 81, 84, 75, 26, 39, 62, 65, 66, 85, 71, 74, 68, 73, 66, 83, 60,58, 72
Venita: 45, 65, 73, 57, 79, 66, 69, 75, 51, 44,53, 69, 58, 77, 51, 55, 53, 78, 70, 62

1. Find the five-number summary of each data set. Then construct box-and-whisker plots of the data sets. Draw
both plots above the same number line. Label the plots with the girls' names.

46.2+112.3

step-by-step explanation:

henry ordered 5 large pizzas

step-by-step explanation:

sorry no step by step

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

probably .5

i can on others if necessary.
