Answer:1/6*1/6*1/6=1/216
Step-by-step explanation:
Answer:
58240
Step-by-step explanation:
Given
Represent cost with c and size with s.
So, we have:
when
Required
Find c when s = 1820
For direct variation, we have:
Write as equation:
when , we have:
So, the equation is:
When s = 1820
Answer:
a)
And replacing we got:
b)
Step-by-step explanation:
Previous concepts
In statistics and probability analysis, the expected value "is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values".
The variance of a random variable Var(X) is the expected value of the squared deviation from the mean of X, E(X).
And the standard deviation of a random variable X is just the square root of the variance.
Solution to the problem
Part a
We have the following distribution function:
Y 0 1 2 3
P(Y) 0.45 0.2 0.3 0.05
And we can calculate the expected value with the following formula:
And replacing we got:
Part b
For this case the new expected value would be given by:
And replacing we got
Molly: = = 5 baskets per minute
Nico: = = 7 baskets per minute
Nico - Molly: 7 - 5 = 2
