Which sequence of transformations produces an image that is not congruent to the original figure?

D

Translations, Reflections, and Rotations are transformations that result in a congruent figure.

Dilations on the other hand don't. They change the size of the figure, which means the transformed figure is not congruent to the original.

<span>Which sequence of transformations produces an image that is not congruent to the original figure?
A. A reflection across the y-axis followed by a rotation of 180 counterclockwise.
B. A rotation of 90 clockwise followed by a translation of 6 units to the left.
C. A translation of 3 units to the left followed by a reflection across the x-axis.

the weights of ten cats in pounds are 14, 10, 11, 9, 12, 8, 8, 10, 7, and 10. what is the mean absolute deviation of the weights

BabaBlast [244]

Answer:

HOW TO DO STEP BY STEP:)

Original set ={14, 10, 11, 9, 12, 8, 8, 10, 7,10}

n = 8 is the number of values in that set above

Add up the values 12+11+7+10+10+11+6+8+14+8 = 97

Divide that sum by n = 8 to get 97/8 = 12. So the mean = 12

For each value in the original set {14, 10, 11, 9, 12, 8, 8, 10, 7,10} subtract off the mean = 12. Apply the absolute value to ensure the result is positive or zero

|x - mean| = |14 - 12| = -2

|x - mean| = |10 - 12| = 2

|x - mean| = |11- 12| = 1

|x - mean| = |9 - 12| = 3

|x - mean| = |12 - 12| =0

|x - mean| = |8 - 12| = 4

|x - mean| = |10 - 12| =2

|x - mean| = |7 - 12| = 5

|x - mean| = |10 - 12| = 2

The set of results we get are: {-2,2,1,3,4,4,2,5,2 } -2,2,1,3,4,4,2,5,= 21, then we divide 21 that over n = 12 (21/12) to get = 1.75

Therefore the mean absolute deviation (MAD) is 1.75

katovenus [111]

The lower end of the range is
42.670 - 0.002 = 42.668 mm

The upper end of the range is
42.670 + 0.002 = 42.672 mm

The range of acceptable values is 42.668 mm to 42.672 mm.

When finding the median, do we have to put the numbers in order from least to greatest

iris [78.8K]

Yes you do. Place all of the numbers, even repeating ones, in order from slammers to largest and then start crossing out from both sides until you get the middle. For example, in the problem below the median would be 4 bc it’s in the middle

Graph the system of inequalities x>3 y≤2x-5

olganol [36]

Answer:

The answer is the last attached picture.

Step-by-step explanation:

First, graph the equation x=3, this is shown in the attached picture, is just a vertical line.

The region x>3 is shown in blue, is everything to the right of the equation x=3.

Next, lets graph the equation y=2x-5, this is shown in the attached picture:

as a leaned line colored in green, to graph this one use two points, the first is where x=0 (find y value), and the other where y=0 (find x value).

The region y<=2x-5 is below that graph, showed in blue.

Finally, intercepting those regions, we have the final picture, starting from x=3 and under the curve 2x-5 to infinity
