 B: Q3=22

Step-by-step explanation:

If you were to create a box plot with this data with the numbers being in order from least to greatest and find the median of the third quartile you would find the answer choice B.

1.  14,16,19,19,20,20,21,21,22,22,23

2.  14,16,19,19,20,"|20|",21,21,22,22,23= 20 is the median

3.  14,16,19,19,20,|  |,21,21,22,22,23= these are your quartiles

4.  14,16,19,19,20,|  |,21,21,"|22|",22,23= the median of the third quartile is 22

I am not sure if I am right but from what I know I think B is the correct answer choice

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
