Answer:

2 ( m + 2 m)  = 36 is the required linear equation

Length of the rectangle is 12 ft and width =  6 ft

Step-by-step explanation:

Let the width of the rectangle = m ft.

So, the length of the rectangle = 2m  ft.

Perimeter  of rectangle = 36 ft

Now, PERIMETER OF THE RECTANGLE = 2(LENGTH + WIDTH)

⇒2 ( m + 2m)  = 36

or, 2 x 3m  = 36

⇒ 6m  = 36  , or m  = 36/6

⇒ m  =6 ft

So, the Width of the rectangle;  =  m = 6 ft

and the Length of the rectangle  = 2 m  = 2 x 6 =  12 ft.

Using a calculator, the slope of the line of best-fit is of 7.2.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

In this problem, the points are given as follows:

(-4,-32), (-2,-8), (0,10), (2,8), (4,32).

Using the calculator, the equation is:

y = 7.2x + 2.

Hence the slope is of 7.2.

Given that y= 7 cm and θ= 49 °, work out x rounded to 1 DP.<br><br> (not drawn to scale.)
Anastaziya [24]

The value of x in the diagram is 6.1 cm.

<h3>What is right-angle triangle?</h3>

A right-angle triangle is a triangle that has 90° as one of the angles in the triangle.

To calculate the value of x in the right-angled triangle above, we use the formula below

Formula:

  • tanθ = y/x............ Equation 1

Make x the subject of equation 2

  • x = y/tanθ............. Equation 2

From the question,

Given:

  • θ = 49°
  • y = 7 cm

Substitute these values into equation 2

  • x = 7/tan49°
  • x = 7/1.15
  • x = 6.1 cm

Hence, the value of x in the diagram is 6.1 cm.
