a rectangular room is three times as long as it is wide, and its perimeter is 80 meters. find the length of the room
Hoochie [10]
Let the width of the room be = x

Length of the room = 3x,  Since it is three times as wide

Perimeter = 80m

Perimeter = 2*(L + W) =  2*(3x + x)  = 80

2*(3x + x)  = 80

2*(4x)  = 80

8x  = 80     Divide both sides by 8

x = 80/8

x = 10,    But length = 3x,  = 3*10 = 30

Length = 30m

Suppose the mean height for men is 70 inches with a standard deviation of 2 inches. What percentage of men are more than 72 inch
hichkok12 [17]

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.

More about the z-score link is given below.
