Answer:
1
Step-by-step explanation:
Slope = y2 - y1 /x2 - x1
x1 = 4
y1 = 2
x2 = 3
y2 = 1
Slope = 1 - 2 / 3 - 4
= -1/-1
= 1
<span>If someone runs 10 miles in 90 minutes their average speed is 6.67 mph</span>
//I'll let x = $5, y = $10
x + y = 13
5x + 10y = 90
So, y = 13 - x
5x + 10(13 - x) = 90
5x + 130 - 10x = 90
-5x = -40
x = 8
We can tell it’s not a permutation because it’s picking two people. Order doesn’t matter.
The number of total possible groups of men is 9 C 2 = 9!/((9-2)!(2!)) = 36
The number of total possible groups of women is 11 C 2 = 11!/((11-2)!(2!)) = 55
55 * 36 = 1980 different groups in the committee
