36 + x  would be your answer. When something is 'increased', you are adding to it. Such as saying 47 increased by -5x is the same as 47 + (-5x).
If this wasn't the answer you were looking for, let me know. For now, I hope this helped:)

A rectangle has length 12 feet and width 8 feet. Every dimension of the rectangle is multiplied by 3/4 to form a similar rectang
kap26 [50]
Let the area of the original rectangle be A₁.

A₁ = (12 ft)(8 feet) = 96 ft²

To determine the area of the reduced triangle, let's compute the new dimensions first.

Length = 12 ft * 3/4 - 9 ft
Width = 8 ft *3/4 = 6 ft

Thus, the area of the new rectangle denoted as A₂ is
A₂ = (9 ft)(6 ft) = 54 ft

The ratio of the areas are:
A₂/A₁ = 54/96 = 9/16
The ratio of the sides are given to be 3/4.
Finally the ratios of the area to side would be:
Ratio = 9/16 ÷ 3/4 = 3/4

Therefore, the ratio of the areas is 3/4 of the ratio of the corresponding sides.

Please help me compute standard deviation! Here is the problem, as written.
aleksandr82 [10.1K]

Answer:

The standard deviation for the income of super shoppers is 76.12.

Step-by-step explanation:

The formula to compute the standard deviation for the grouped data probability distribution is:

\sigma=\sqrt{\sum [(x-\mu)^{2}\cdot P(x)]}

Here,

<em>x</em> = midpoints

\mu=\sum x\cdot P(x)

Consider the Excel table attached below.

The mean is:

\mu=\sum x\cdot P(x)=32.3

Compute the standard deviation as follows:

\sigma=\sqrt{\sum [(x-\mu)^{2}\cdot P(x)]}

   =\sqrt{259.71}\\\\=76.1155204\\\\\approx 76.12

Thus, the standard deviation for the income of super shoppers is 76.12.

Dilate the triangle with a scale factor of 2 and a center of dilation at the origin
satela [25.4K]

Answer:

To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2. I plotted all the new points to find the new triangle. To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2.

The picture below shows a dilation with a scale factor of 2. This means that the image, A', is twice as large as the pre-image A. Like other transformations, prime notation is used to distinguish the image fromthe pre-image.

aivan3 [116]

Answer:

Step-by-step explanation:

5x+20 = 0

5X= -20

X= -20/5 = -4

8(4n+3) = 32n+24 =0

32n = -24

n = -24/32 = -3/4

12n-6=0

12n =6

n = 6/12 = 1/2

9(2x+9)

18x+81 =0

18x= -81

x= -81/18 = -9/2= -4.5

36+9y=0

36=-9y

36/-9 = y = -4

7(n-3) = 0

7n-21=0

7n = 21

n = 21/7

n=3

21+15a = 0

21= -15a

a= 21/-15 = 7/-5 = -1.4

32x-12x=0

20x=0

x=0/20 = 0

n-4-9=0

n-13=0

n=13

-3x-9+15x=0

-3x+15x-9 =0

12x-9=0

12x=9

x=9/12 = 3/4 = 0.75

-16N-14N=0

-30n=0

n=0/-30 =0

-10-90x-6x-10x²-2

-10-2-96x-10x²

-12-96x-10x²

10x²+96x+12

x= -b±√b²-4(a)(c)/2a

   {-96±√96²-4(10)(12)}/2(10)

{-96±√(9216-480)}/20

-96±√8736/20

-96±(93.4665715644)/20

-96+93.4665715644/20        -96-93.4665715644/20

-2.5334284356/20                 -189.466571564/20

-0.12667142178≅ -0.13             -9.4733285782≅ -9.47

-0.13                                                -9.47

-5(9n+9) =0

-45n-45 =0

-45n = 45

n = 45/-45 =-1

-5n+3(6+7n)

-5n+18+21n=0

-5n+21n+18 =0

16n+18 =0

16n = -18

n = -18/16 = -9/8 = -1.125

-4+7(1-3n)=0

-4+7-21n=0

3-21n=0

3=21n

3/21=n = 1/7

3n-(2n-8)

3n-2n+8=0

n+8=0

n=-8
