The two given equations are vertical angles, which mean they are the same.
Set the two equations to equal and solve for x:
13x-23 = 5x+17
Add 23 to each side:
13x = 5x+40
Subtract 5x from each side:
8x = 40
Divide both sides by 8:
x = 40/8
x = 5
Answer: 2.36
Step-by-step explanation:
Using the μ=∑[x⋅P(X=x)
U will need to do
2/11 because you have 2 labeled 1
3/11 because you have 3 labeled 2
6/11 because you have 6 labeled 3
Then you will do:
1 x 2/11 = 0.18
2 x 3/11 = 0.5454 = 0.55
3 x 6/11 = 1.63
Then add them all together to find the μ
0.18 + 0.55 + 1.63 = 2.36
Hope that helps, plz put a good rating
