Answer:
B. 4
Step-by-step explanation:
Interval: 19-21
Scores that are between 19 and 21 are underlined:
Scores in order: <u>20, 21, 21, 21</u>, 23, 25, 26, 27, 27, 29
Answer:
D
Step-by-step explanation:
74 + 93 + 117= 284
360 - 284 = 76
Using the intersecting chord theorem:
15 x 2 = 5 x n
Simplify:
30 = 5n
Divide both sides by 5:
n = 30/5
n = 6 m
8 x n+8 = 16 x n+2
Simplify:
8n +64 = 16n +32
Subtract 8n from both sides:
64 = 8n +32
Subtract 32 from both sides:
32 = 8n
Divide both sides by 8:
n = 32 /8
n = 4
Step-by-step explanation:

You have to use the formule: y2-y1/x2-x1
-2-(-2)/4-(-3)=0/7
