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
A. 1/11
Answer:
c = 3(b + 1)
Step-by-step explanation:
c = 4b - 1b + 3
4b - 1b = 3b
c = 3b + 3
3 is a common factor of both terms on the right hand side
Factorizing the expression
c = 3(b + 1)
Vertical angles are always equal. The vertical angles are the ones opposite each other. Therefore x would equal 40.
Answer:
A
Step-by-step explanation:
Since its parallel to y=3x+1, the slope must be the same so now we are left with A and D. If you put (1,2) into A, it is true so it is A
