Answer:B
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
3x + x + 100 = 180 (sum of angles on a straight line)
4x = 180-100
4x=80
divide both sides by 4
x=20
Answer:
1.15
Step-by-step explanation:
Multiply each shot by its point value. Then add. Divide this sum by the total number of shots taken.
288*2 + 79*3 + 340*0 = 813
----------------------------------------
288 + 79 + 340 = 707
813 / 707 = 14.992
The weighted average is approximately 1.15 points per shot.
The last option: In his recursive formula, he should have the term an−1 instead of −4 to get an=an−1−3.
