Answer:
175 square feet
Step-by-step explanation:
the area of the whole thing is 400 ft. (20 x 20=400)
i got the 20 from the perimeter b/c 20+20+20+20=80
then subtract the area of the pool from 400 to get 175.
The probability of selection 2 black cups one after another one without replacement is 1/91
<h3>What is the probability of selection 2 black cups one after another one without replacement?</h3>
The given parameters are:
Green = 4
Blue = 8
Black = 2
Given that the selection is without replacement, this means that the number of cups reduces when one is selected
So, we have:
P(2 Black cups) = P(Black) * P(Black)
This gives
P(2 Black cups) = 2/(4 + 8 + 2) * (2 - 1)/(4 + 8 + 2 - 1)
Evaluate
P(2 Black cups) = 2/14 * 1/13
This gives
P(2 Black cups) = 1/91
Hence, the probability of selection 2 black cups one after another one without replacement is 1/91

V(x) = (2x - 3)/(5x + 4)
The domain is all Real numbers except x = -4/5, because if x = -4/5 the denominator would be zero and you cannot divide by zero.
{x | x ∈ R, x ≠ -4/5}
w(x) = (5x + 4)/(2x - 3)
similarly, x ≠ 3/2
so, {x| x ∈ R, x ≠ 3/2}
