Step-by-step explanation:
VAT = 250*15%
VAT = 250*15/100
VAT = 37.5 therefore
total price add VAT =250+37.5
=287.5
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
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.
