Step-by-step explanation:
Given data
2 green,
9 brown,
7 yellow, and
4 blue marbles.
Sample space S = 2+9+7+4= 22
The probability of picking a ball without replacement
Probability of picking each ball
Pr(green) = 2/22= 1/11
Pr(brown ) = 9/21
Pr(yellow) = 7/20
Pr(blue) = 4/19
Probability of picking yellow then another yellow
P(yellow, then yellow)
=(7/22)*(6/21)= 42/462
=1/11

D will be The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
Answer: The slope is 3.
Explanation: the slope is three because every point goes up by three (and over to the right one) in order to get to the next point on the graph
Length of the perpendicular "" = 5.
