Answer:
16 inches x 13 stairs = 208 inches. 208 inches/12 = 17.33 (round up) = 18 feet. 4 x 18 = 72 square feet. Width is 4 feet.
Step-by-step explanation:
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.

Answer: The numbers on a distance of 3.2 units from −4 on a number line are -7.2 and - 0.8 .
Step-by-step explanation:
The numbers on a number line are from - infinity to + infinity whose center is at 0.Om left sides of 0 , there are negative integers and on the right side there are positive integers.
So, The numbers on a distance of 3.2 units from −4 on a number line are
-4 - 3.2 and -4+3.2
= - (4+3.2) and - (4-3.2)
= -7.2 and - 0.8
Hence, the numbers on a distance of 3.2 units from −4 on a number line are -7.2 and - 0.8 .
Answer: 1, 4, -7
Step-by-step explanation:
Coefficients are numbers that are in front of a variable. Let's first determine the terms that have variables in them.
z, 4z², -7a
Since these all have variables in the terms, we know the coefficients are 1, 4, -7.
