Step-by-step explanation:
We are picking 3 balls from 30 balls, so its C(30,3) because the order of picking the balls doesnt matter. We also need to pick 2 balls from 20 balls, which is C(20,2). So the answer is C(30,3) * C(20,2).
Answer:
Step-by-step explanation:
Slope of a line between two points is given as (y2 - y1)/(x2 - x1)
Given the points: (11, -10) and (11, 4)
This implies: x1 = 11, x2 = -10, y1 = 11, y2 = 4
Slope = (4 - 11)/(-10 - 11)
Slope = -7/-21
Slope = 1/3
Answer:
0.00604
Step-by-step explanation:
The exponent tells us how many spaces to move the decimal in a given number. If its positive, the decimal moves to the right. If its negative, the decimal moves to the left.
