Answer:
The sample of sizes 2 and their mean are given below.
Step-by-step explanation:
The population consist of 5 values, S = {1, 3, 4, 4, 6}.
The number of samples of size 2 (without replacement) that can be formed from these 5 values is:
![{5\choose 2}=\frac{5!}{2!(5-2)!} =10](https://tex.z-dn.net/?f=%7B5%5Cchoose%202%7D%3D%5Cfrac%7B5%21%7D%7B2%21%285-2%29%21%7D%20%3D10)
Th formula to compute the mean is:
![\bar x=\frac{1}{n}\sum x_{i}](https://tex.z-dn.net/?f=%5Cbar%20x%3D%5Cfrac%7B1%7D%7Bn%7D%5Csum%20x_%7Bi%7D)
List the 10 samples and their mean as follows:

Which number(s) from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, if any, will solve this equation?
marissa [1.9K]
Answer:
A or 2 is the correct answer.
Step-by-step explanation:
2x + 3 = 5x - 3
2(2) + 3 = 5(2) -3
7=7
Because there is 5 in both of the numbers:
5 and 0.5
Answer:
19 or 21.
Step-by-step explanation:
I swear.
5 + 5 = 10
10 + 5 = 15
15 + 4 = 19
________________
9 + 9 = 18
18 + 10 = 28
28 - 5 = 23
There are two nines so
23 - 2 = 21
