A rectangle is 3 times as long as it is wide. if the area is 27 square feet, find its perimeter.
Marat540 [252]
W - a width
3w - a length
27 ft² - an area

Therefore:

w · 3w = 27
3w² = 27    |:3
w² = 9 → w = √9 → w = 3

3w = 3 · 3 = 9

width = 3
length = 9

The perimeter:

P = 2 · width + 2 · length

P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.

A continuous random variable may assume :
vova2212 [387]

Answer:

Option A) any numerical value in an interval or collection of intervals

Step-by-step explanation:

Continuous Random Variable:

  • A continuous random variable can take any value within an interval.
  • Thus, it can take infinite values since there are infinite numbers in an interval.
  • A continuous variable is a variable whose value is obtained by measuring.
  • Examples: height of students in class , weight of students in class, time it takes to get to school, distance traveled between classes.
  • Thus, the correct meaning of continuous random variable is explained by Option A)

Option A) any numerical value in an interval or collection of intervals

Q4. The diagram shows a triangle inside a rectangle.
Yanka [14]

The prove to show that the area of the shaded portion is 18x  - 30 is as follows: 3x² + 13x - 30 - 3x² + 5x = 18x  - 30

<h3>How to find the area of the shaded region?</h3>

The area of the shaded region can be represented as follows:

area of the shaded region = area of rectangle - area of triangle

Therefore,

area of the rectangle = (x + 6)(3x - 5)

area of the rectangle = 3x² - 5x + 18x - 30

area of the rectangle = 3x² + 13x - 30

area of triangle = 1 / 2 × 2x × 3x - 5

area of triangle = 3x² - 5x

Therefore,

area of the shaded portion =  3x² + 13x - 30 - 3x² + 5x

area of the shaded portion = 18x  - 30
