Suppose U= {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P= {1, 2, 3, 4}. What is P?
Digiron [165]
Did you mean P' ? The letter P with a tick mark after it. If so, then start with set U and erase any number you find in set P
We start with
{1,2,3,4,5,6,7,8}
and we erase the following: 1,2,3,4
since those numbers are in set P
P = {1,2,3,4}
P ' = {5, 6, 7, 8}
<span>The set P' is the complement of set P. It is, in a sense, the opposite of set P. It contains everything that P doesn't have.</span>
The correct answer is choice C. The mean absolute deviation is a way to show the variability, or how spreadout the data is. When the mean absolute deviations are close to each other, that tells us that they're comparable in how they vary. 6.9 is close to 7.1.
Answer:
Camille did it right.
Step-by-step explanation:
4x-2y=8
Charlize: | Camille:
-2y=8+4x | -2y=8-4x
y=-4-2x | y=-4+2x
The right answer:
4x-2y=8
+2y +2y
4x=8+2y
-8 -8
2y=4x-8
2y/2=4x/2-8/2
y=2x-4 or y=-4+2x
So Camille is right, because she got y=-4+2x.
