Answer:
27
Step-by-step explanation:
Put this into numbers:
Use Order of Operations to simplify. First, you would do the stuff in parentheses which is:
Inside of those parentheses first simplify the exponents:
Now add
So the new equation is:
The next step is to simplify the exponents
Multiply out the top
Divide this
Answer:
a. 0.80
b. $80
Step-by-step explanation:
a. The expected value, E(Y) is the sum of: [(each of the possible outcomes) × (the probability of the outcome occurring)]. In more concrete terms, the expectation is what you would expect the outcome of an experiment to be on average:
Hence the expected value E(Y) is 0.80
b. From a above we have the expectation as E(Y)=0.80.
-The expected amount is calculated by multiplying expectation by the surcharge:
Hence, the expected amount of surcharge is $80
Hello, please consider the following.
We can estimate the discriminant, and then, the solutions and we take the largest one.
Thank you
