Answer:
The probability mass function of random variable X which represents the number of blue marbles drawn in 2 draws with replacement.
X | P(X)
0 | 0.390625
1 | 0.46875
2 | 0.140625
The probability of drawing exactly one blue marble = 0.46875
0.46875 as a simplified fraction is ------ 15/32
Step-by-step explanation:
Answer:
0.25
liter of red paint, 0.25 liter of blue paint,
and 4.5 centiliters of white paint.
Step-by-step explanation:
Okay, so one of the geometric theorems is that two of the inside angles equals the outside angle in a situation like this one.
So, set them equal:
2x+ 2 + 4x + 8 = 8x - 30
Combine like terms:
6x + 10 = 8x - 30
40 = 2x
x = 20
Answer:
The domain should be on the x-axis.
I might be wrong.
Answer:
33
Step-by-step explanation:
6z - 18 = 180
6z = 198
z = 33
