Before outlier : 7.25

7.25 - 4 = 3.25

So the mean decreases by 3.25 when the outlier is removed.

The vertices of a figure are given. Find the coordinates of the figure after the transformations given. A(−5,3),B(−2,3),C(−2,1),D(−5,1)Reflect in the y-axis. Then dilate with respect to the origin using a scale factor of 2. (help please))!!!

Answers

Answer:

Reflection: A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

Dialation: A"(10, 6)

                B" (4, 6)

                C" (4, 2)

                D" (10, 2)          

Step-by-step explanation:

A(−5,3),B(−2,3),C(−2,1),D(−5,1)

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

                   A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

To dialate by a scale factor of 2 you multiple everything by 2 and you should get:           A"(10, 6)

               B" (4, 6)

               C" (4, 2)

                D" (10, 2)

The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perimeter would be 62 inches. What is the width and length of the rectangle? If w represents the width of the rectangle, then which equation could be used to solve for w?
2(4 w + 3) = 62
( w + 1)(3w + 2)=62
2(3 w + 3) = 62

Answers

pretty sure it’s the second option because length would be 3w+2
and width would be w+1 and with area you have to multiply so it would just be the (w+1)(3w+2)

Answer:

     2(4 w + 3) = 62

          width  =7      length = 21

Step-by-step explanation:

For the perimeter you need :

2 times the width     and    2 times the length (length =3w)

so

2(w+1) + 2 (3w+2) =

2w+2 + 6w+4 =

8w +6

you  can factor this by:

2(4w+3)

                      8w +6= 62

                       8W = 56

                      w= 7      l= 21

                    2(7+1)  + 2 (21+2)

                           16 +  46 = 62

Step-by-step explanation:

the complement of an angle is an angle that when added to the original angle = 90°

Answers

Answer:

From 12 o'clock position clockwise:

-12

-1

11

12

Step-by-step explanation:

y = -1 (given).

x + y = 11

Plug in -1 for y in the equation (given):

x + (-1) = 11

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 1 to both sides of the equation:

x - 1 (+1) = 11 (+1)

x = 11 + 1

x = 12

x + y = ?

x = 12

y = -1

Plug in the corresponding numbers to the corresponding variables:

12 + (-1) = 12 - 1 = 11

xy = ?

x = 12

y = -1

Plug in the corresponding numbers to the corresponding variables. Note that when you multiply a negative and a positive number, your answer will be negative:

12 * -1 = -12

Since Y is -1, X is 12 because 12+-1= 11. Oh and 12•-1 is -12.
