The answer is C.................................................
The triangle defined by three points on the coordinate plane is congruent with the triangle illustrated:
C) (4,2); (8,2); (4,8) because the corresponding pairs of sides and corresponding pairs of angles are congruent.
If we plot these points we can observe that they are congruent, we should also solve for the distance of each point between each other to conclude their congruency.
Answer:
hope that this picture answers it
Answer:

If we solve for k we can do this:




So then we have at last 75% of the data withitn two deviations from the mean so the limits are:


Step-by-step explanation:
We don't know the distribution for the scores. But we know the following properties:

For this case we can use the Chebysev theorem who states that "At least
of the values lies between
and
"
And we need the boundaries on which we expect at least 75% of the scores. If we use the Chebysev rule we have this:

If we solve for k we can do this:




So then we have at last 75% of the data withitn two deviations from the mean so the limits are:


HELLO,
Your answer is 130-50=80
You would have to make 80 dollars,
So 8 dollars per hour (of course that is below minimum wage that means you need a raise).
Therefore, you need to mow lawns for 10 hours
Thanks for posting your question here on brainly.
Hope this helps you.
Let me know if its correct.
