Answer:
Step-by-step explanation:
Given, :
x P(x)
0 0.900
1 0.09
2 0.007
3 0.003
The expected variance ; Var(X) = x²*p(x) - E(X)²
The expected mean, E(X) = x*p(x)
E(X) = (0*0.9) + (1*0.09) + (2*0.007) + (2*0.003) = 0.113
Var(X) = [(0^2*0.9) + (1^2*0.09) + (2^2*0.007) + (3^2*0.003)] - 0.113^2
Var(X) = 0.145 - 0.012769
Var(X) = 0.132
For this case we observe that we have a triangular prism.
The triangular prism has two triangles.
A triangle for the base of the prism.
A triangle for the top of the prism.
The lateral faces of the prism are rectangular.
Answer:
Are needed:
2 triangles
The correct answer is 36 - there are 36 more beef cattle on the farm
than dairy cattle. We can work this out by multiplying 16 by 3 to get
48. 48 take 12 is 36. 16 is one fourth, 24 is two thirds, which means
you then need to divide this by two to get 12, which means that 12 is
one third.
Answer:
5 days
Step-by-step explanation:
There are 16 quarts in 4 gallons of milk, so if they drink 3 quarts every day just divide 16 by 3 which will give you 5.3 but rounding your answer is 5 days.
I hope this helps!!
