Well 58.19 divided by 2.74 will equal 21 and random number after decimal so it will be 21 days
Expected Mean, E(X), is obtained by multiplying each pair of

and its

and add up the answers
E(X) = (0×0.7) + (1×0.2) + (2×0.1) = 0.4
The formula to calculate the variance, Var(X), is given by E(X)² - (E(X))²
E(X²) = (0²×0.7) + (1²×0.2) + (2²×0.1) = 0+0.2+0.4 = 0.6
(E(X))² = (0.4)² = 0.16
Var(X) = 0.6 - 0.16 = 0.44
Translating these answers into the context we have
E(Y) = 0.4×500 = $200
Var(Y) = $110
Answer:I think 10
Step-by-step explanation: fd=20/52 is 30 f
It is not enough to describe the oppostite rays only with the statement that they have the same endpoint. Besides the same endpoint opposite rays are characterized with opposite drection.
So, the student should answer: VW and VZ are opposite rays because they have the same endpoint and the the opposite direction.
Answer: 14° (APEX)
