Answer:
(13, -6.5)
Step-by-step explanation:
Find the distance between points J and the midpoint, which is 8.5 for x-coordinates and 2.5 for y-coordinates.
Add these values to the midpoint coordinates to get the coordinates of point K
4.5 + 8.5 = 13
-8.5 + 2.5 = -6.5
The coordinates of point K are (13, -6.5)
Answer:

Step-by-step explanation:

The population standard deviation
First, calculate the population mean

This gives:



The population standard deviation is:

So, we have:




<span>Is that supposed to be:
(a²b³)⁴
If so, the exponent of an exponent is the product of the exponents, so we end up with:
a⁸b¹²</span>
