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

Answer:
area of triangle = 135 mm²
Step-by-step explanation:
Area of a triangle = 1/2 × b × h
Area of a triangle = 1/2 × 27 × 10
Area of a triangle = 135 mm²
For this case, what we can do is calculate an average of the time it takes to fill the tank for both pipes.
We have then:
taver = (tA + tB) / (2)
Where,
taver: average time (both pipes)
tA: time it takes the pipe A
tB: time taken by pipe B
Substituting the values:
9.9 = (18 + tB) / (2)
Clear tB:
tB = (2 * (9.9)) - 18
tB = 1.8 hours
Answer:
it takes pipe B, running alone, to fill the tank about 1.8 hours
