Answer:
A.
Step-by-step explanation:
Since VA and BC are equal in length so their central angles would also be equal.
So
<VWA = <BWC
32x-27 = 120
32x = 120+27
32x = 147
Dividing both sides by 32
x ≈ 4.6
The percentage of men is more than 72 inches tall will be 0.15866.
<h3>What is the z-score?</h3>
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x – μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
Suppose the mean height for men is 70 inches, with a standard deviation of 2 inches.
Then the percentage of men are more than 72 inches tall will be
z = (72 – 70) / 2
z = 1
The percentage of men is more than 72 inches tall will be
P(x > 72) = P(z > 1)
P(x > 72) = 1 – P(x < 72)
P(x > 72) = 1 – 0.84134
P(x > 72) = 0.15866
Thun, the percentage of men are more than 72 inches tall will be 0.15866.

52 = (2*W - 5) * W
52 = 2*W^2 - 5*W
0 = 2*W^2 - 5*W - 52
0 = (2W - 13)*(W + 4)
2W - 13 = 0 or W + 4 = 0
W = 13/2 or W = -4
Width cannot be negative so discard W = -4
W = 13/2 L = 2*(13/2) - 5 = 13 - 5 = 8
Answer:
Step-by-step explanation:
To solve this problem, we want to make sure the denominators are the same on both fractions. Once they are equal, we can dd them together.
[multiply first fraction by y+4 and second by y-8]
[distribute by FOIL]
[add numerator]
[combine like terms]
[factor out 2 from numerator]
Now we know that is the factored form after adding.
