Elena, Jada, and Lin enjoy playing basketball during recess. Lately, they have been practicing free throws. They record the number of baskets they make out of 10 attempts. Here are their data sets for 12 school days.

Elena: 4 5 1 6 9 7 2 8 3 3 5 7

Jada: 2 4 5 4 6 6 4 7 3 4 8 7

Lin: 3 6 6 4 5 5 3 5 4 6 6 7

Calculate the mean number of baskets each player made, and compare the means. What do you notice?

They all have the same mean of 5

Step-by-step explanation:

first add up all the numbers in each data set separately and then divide by the total number (12) to find the mean  for example

Elena: 4+5+1+6+9+7+2+8+8+3+3+5+7= 60

60 divided by 12 equals 5

all three have the same mean of 5

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
