The first step would be to isolate the square root on the left side. √x-6+2 = 6 √x-6 = -2+6 √x-6 = 4We would have to take away the radical on the left and square the equation. (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22
Answer:
6 blue marbles
Step-by-step explanation:
Given;
Total number of marbles N = 15
probability of randomly selecting a green marble
P(G) = 1/5
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble P(G∩B) = 2/25
P(G∩B) = P(G) × P(B)
P(B) = P(G∩B) ÷ P(G)
The probability of selecting a blue marble
P(B) = 2/25 ÷ 1/5 = 2/5
The number of blue marbles N(B) = P(B) × N
N(B) = 2/5 × 15 = 6
There are 6 blue marbles
There is a strong, positive association
I believe the angle that is congruent to angle 1 is angle 2
The answer would be A.
