Using the graph and the percentile concept, it is found that:

The 20th percentile represents about 67 inches, meaning that 20% of the people in the group are shorter than 67 inches.

<h3>What is the percentile concept?</h3>

When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.

In the graph:

The x-axis is the height.

The y-axis is the percentile.

When y = 20, x = 67, which means that:

The 20th percentile represents about 67 inches, meaning that 20% of the people in the group are shorter than 67 inches.

Alexxx [7]

Hi,

Let the

Youngest brothers age = x+2

Middle brothers age = x+4

Oldest brothers age = x+6

So,

Youngest brothers age = x+2 = 28+2 = 30 years of age

Middle brothers age = x+4 = 28+4 = 32 years of age

Oldest brothers age = x+6 = 28+6 = 34 years of age

Have a great day!

Perimeter of a rectangle is 52 feet. If the length is 10 less than 2 times the width, what is the width?

ella [17]

Step-by-step explanation:

Let the width be x feet.

Therefore, length = 2x - 10

Perimeter of rectangle = 52

$2(2x - 10 + x) = 52 \\ 2(3x - 10) = 52 \\ \therefore \: 3x - 10 = \frac{52}{2} \\ \therefore \: 3x - 10 = 26\\ \therefore \: 3x = 26 + 10\\ \therefore \: 3x = 36 \\ \therefore \: x = \frac{36}{3} \\ \therefore \: x = 12 \\ \purple{ \boxed{\therefore \: width \: of \: rectangle = 12 \: feet }}$
