Without using a protractor to measure exactly, choose the best possible measurement of the angle above.
a. 90°
b. 45°
c. 85°
d. 160°

Step-by-step explanation:

The slanting line has a slope of approximately 1, so the angle this line makes with the horiz. axis is approx. 45 degrees.

B

Step-by-step explanation:

It's not going to be a right angle. The two lines of a right angle are perpendicular. A is incorrect.

C is incorrect. 85o is pretty close to 90 degrees. That angle is nowhere's near that large.

D is incorrect. 160 degrees is nearly a straight line. The angle shown isn't.

That leaves B.

B looks to be 45 degrees and since the others are incorrect, B must be your answer.

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
