<u>Answer:</u>
The correct answer option is C. Both A and B.
<u>Step-by-step explanation:</u>
We are given a figure of a rectangle which when transformed changes it length of two sides AB and DC to AB' and DC'.
By looking at the figure, we can conclude that the transformation has changed the lengths of some sides of the given figure as well as changed the area of the figure.
Therefore, the correct answer option is C.
So So sorry, I answered so late xd
The mean can be found by adding all the numbers then dividing it by the amount of numbers
The mean for team A is about 7.7
and the mean for team B is about 7.6
So they're A.) About the same
To find the range find the biggest number then subtract it by the smallest
Team A: 12,0 ; 12 - 0 = 12
12 is the range
Team B: 12,3 ; 12 - 3 = 9
The answer is B.) <span>much greater for conference a than for b</span>
Answer:
4 and 5
Step-by-step explanation:
Make a system of equations:
x+y=9
x-y=-1
x=9-y
9-y-y=-1
9-2y=-1
-2y=-10
y=5
Since y=5, x must be 4 since 4+5=9 and 4-5=-1
Hope this helped!
