To calculate the mean absolute deviation, you first must find the mean of the data and then find the difference between each piece of data and the mean.

Please see the attached picture for the work.

The mean absolute deviation is approximately 1.48.

This means that the numbers of candies in the 10 bags are all very close to one another. There is not much variation.

IF SOMEONE COULD HELP WITH THIS IT WOULD BE MUCH APPRECIATED!
julsineya [31]

Answer:

48 Units

Step-by-step explanation:

Use the Pythagorean theorem to make two right triangles.

Ex= Base is cut in half to make two 9 unit bases

Then count the units from the half point.

Ex= 12 units long

Then use Pythagorean theorem to find one side of the 9-12 right triangle

Ex= 9^2+12^2=c^2

After finding that c=15 units, add all the sides back together

Ex= 18+15+15=48

Polygons ABDC and A′B′D′C′ are shown on the following coordinate grid:
weeeeeb [17]

Answer: A

Step-by-step explanation:

Let's first review how turning about the origin changes a point's coordinates:

After rotating and translating some points, one can see the following pattern:

  • 180° Rotation: (x,y) -> (-x,-y)
  • 90° Clockwise Rotation: (x,y) -> (y, -x)
  • 90° Counter-clockwise Rotation: (x,y) -> (-y, x)
  • Translation <em>a</em> units to the left: (x, y) -> (x-a, y)

Using these patterns will make it much easier to find the correct series of transformations than graphing each one.

A: A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left

Using the patterns found above, this set of transformations would make (x,y) move first to (-y, x), then (-y-1, x).

  • A(2,-2) -> A'(1,2)
  • B(4,-2) -> B'(1,4)
  • D(5,-3) -> D'(2,5)
  • C(1,-3) -> C'(2,1)

B: A translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin

This would make (x,y) move first to (x-1,y), then to (-y, x-1)

  • A(2,-2) -> A'(2, 1)
  • B(4,-2) -> B'(2,3)
  • D(5,-3) -> D'(3,4)
  • C(1,-3) -> C'(3,0)

C: A 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left

This would make (x,y) move first to (y, -x), then (y-1, -x)

  • A(2,-2) -> A'(-3, -2)
  • B(4,-2) -> B'(-3,-4)
  • D(5,-3) -> D'(-4, -5)
  • C(1,-3) -> C'(-4, -1)

D: A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin

This would make (x,y) move first to (x-1,y), then (y, -x+1)

  • A(2,-2) -> A'(-2, -1)
  • B(4,-2) -> B'(-2, -3)
  • D(5,-3) -> D'(-3, -4)
  • C(1,-3) -> C'(-3, 0)

Therefore, the answer is A, as only it correctly matches to polygon A'B'D'C'.
