Answer:
Step-by-step explanation:
If we choose chairs having odd number in the row
no of chairs from which selection is made = 10
no of chairs to be selected = 5
no of ways = 10C₅
similarly if we choose hairs having even numbers only ,
similar to above , no of ways
= 10C₅
Total no of ways
= 2 x 10C₅
= 2 x 10 x 9 x 8 x 7 x 6 / 5 x 4x3 x 2 x 1
= 504 .
Answer:
15
Step-by-step explanation:
5 X 10 = 50
170 / 50 = 3 sets = 15
Answer:
4
Step-by-step explanation:
Slope equation:
y1 = -6
y2 = 14
x1 = -2
x2 = 3
y2-y1 = 14 - (-6) = 20
x2-x1 = 3 - (-2) = 5
20/5 = 4
Answer:
114°
Step-by-step explanation:
The measure of an arc is double the measure of the angle between the chord and the tangent line.
The answer is C because the scale of the graph does not start from 0 so the differences are smaller
