Thomas is researching locations to live after high school and asks his family members about the number of different places they have lived. let a be the set of the number of places where nine of thomas' family members have lived after high school. a = {3, 2, 7, 8, 6, 8, 3, 4, 3} thomas forgot that his uncle traveled with the military and has lived in 15 different places since high school. let b represent the set of the number of places where all ten of his family members, including his uncle, have lived after high school. select the true statement. the interquartile range of a is 0.5 more than the interquartile range of b. the mean of b is the same as the mean of a. the interquartile range of a is 1.5 less than the interquartile range of b. the mean of b is greater than the mean of a.

D for plato users

Step-by-step explanation:

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
