Mathematics
1 answer:

Answer:

x = 15, AOB = 15, BOC = 165

Step-by-step explanation:

Assume that this is a straight line

2x - 15 + 11x = 180

Combine like terms

13x - 15 = 180

Add 15 on both sides

13x = 195

Divide 13 on both sides

x = 15

Substitute x for 15 in both equations

2(15) - 15 = 15

11(15) = 165

(For checking purposes, 165 + 15 = 180)

Stephen found the line of best fit to be p=-23+0.13y predict the average points per game to the nearest tenth for values of 350,
NISA [10]
P = -23 + 0.13y

For y = 350:
p = -23 + 0.13(350) = -23 + 45.5 = 22.5

For y = 400:
p = -23 + 0.13(400) = -23 + 52 = 29

For y = 450:
p = -23 + 0.13(450) = -23 + 58.5 = 35.5
