Answer:
(d)
Step-by-step explanation:
Multiple your numbers out first. This always makes it less hectic to look at. Multiply both sides by x to move the x to the right side. Then divide both sides by ((0.4365)(87.9)). You should get 10.
Answer:
X 0 1 2 3
P(X) 0.27 0.51 0.17 0.05

And replacing we got:

Step-by-step explanation:
Let X the random variable that represent "the number of buckets of popcorn purchased by patrons during one night at the movies"
And we have the following distribution for X
X 0 1 2 3
P(X) 0.27 0.51 0.17 0.05
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.
For this case we can calculate the expected value with the following formula:

And replacing we got:

Answer:
It should look like this

Answer:
c = 0.75j
Step-by-step explanation:
divide $4.50 by 6 to find the price of one bottle of pineapple juice
4.50/6 = 0.75
each bottle of pineapple juice is 75 cents each
c = 0.75j
