Answer:

Median will not be affected by the outlier.

Step-by-step explanation:

Determine the lengths of the sides of the rectangle using the given area. Give answers both exactly and
Degger [83]

Answer:

Part a) Exactly values

The width of the rectangle is \frac{\sqrt{70}}{2}\ cm

The length of the rectangle is 2\sqrt{70}\ cm

Part b) Approximately values

The width of the rectangle is 4.2\ cm

The length of the rectangle is 16.7\ cm

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of rectangle is equal to

A=LW

we have

L=4x\ cm\\W=x\ cm

substitute the values in the formula

A=4x(x)

A=4x^2

A=70\ cm^2

so

70=4x^2

Solve for x

Divide by 4 both sides

\frac{70}{4}=x^2

square root both sides

x=(+/-)\frac{\sqrt{70}}{2}

The solution is the positive value

x=\frac{\sqrt{70}}{2}

therefore

<em>Exactly values</em>

L=4\sqrt{70}}{2}=2\sqrt{70}\ cm\\\\W=\frac{\sqrt{70}}{2}\ cm

<em>Approximately values</em>

L=4\sqrt{70}}{2}=16.7\ cm\\\\W=\frac{\sqrt{70}}{2}=4.2\ cm

didn't give clear instructions on what to do. I just assumed you add them. answer is down below. :)

Step-by-step explanation:

if ur supposed to add them then

1. 1/8 + 8/8 + 3/8 = 12/8 = 1 1/2

2. 1/4 + 2/4 + 1/4 = 4/4 = 1

3. 1/8 + 8/8 + 4/8 = 1 5/8

4. 1/4 + 1/4 + 2/4 = 4/4 = 1

5. 1/4 + 1/4 + 1/4 + 1/4 = 1
