Answer:

The sandals cost before tax $25.

Step-by-step explanation:

Let us assume that the sandals cost before tax $x.

So, after giving an 8% tax the price will be x(1 + \frac{8}{100}) = 1.08x.

If the $15 gift certificate on that after tax price and the final cost of the sandals becomes $12, then

1.08x - 15 = 12

⇒ 1.08x = 27

⇒ x = $25

Hence, the sandals cost before tax $25. (Answer)

Answer:

Range = 29

Variance=   (X₁- U) ² / N= 973/10 = 97.3

Standard Deviation= √variance= √97.3=  9.864

Step-by-step explanation:

Range = Difference between the highest and lowest value = 97-68= 29

Variance

                  X₁                X₁-U               (X₁- U) ²              

                 80               0                     zero

                 68                -12                   144

                 71                 -9                     81

                 72                -8                     64

                 95                 15                    225                  

                89                  9                     81

                97                   17                   289

                72                    -8                 64

                75                     -5                 25

                81                     1                   1

∑              800                ZERO            973  

u=  ∑X₁ /10=800/10=80

Variance=   (X₁- U) ² / N= 973/10 = 97.3

Standard Deviation= √variance= √97.3=  9.864

(b) The important feature of the data is not revealed through the different measures of​ variation is that the variability of two or more than two sets of data cannot be compared unless a relative measure of dispersion is used .

The length of a rectangle is 1 foot more than twice the width the perimeter is 44 feet find the dimensions of the rectangle
Annette [7]

The length of rectangle is 15 feet and width is 7 feet.

Step-by-step explanation:

Given,

Width of rectangle = w

Length of rectangle = 2w+1

Perimeter = 44 feet

Perimeter = 2(Length+Width)

Perimeter=2(2w+1+w)\\44=2(3w+1)\\44=6w+2\\44-2=6w\\42=6w\\6w=42

Dividing both sides by 6

\frac{6w}{6}=\frac{42}{6}\\w=7

The width of rectangle is 7 feet.

Length of rectangle = 2(7)+1 = 14+1 = 15 feet

The length of rectangle is 15 feet and width is 7 feet.

Keywords: rectangle, perimeter
