Step-by-step explanation:
The question is incomplete..
The given parameters can only solve for the number of hours the battery can last if at full capacity.
Given
25% = 4.5 hours
Required
Determine the brand
First, we need to determine the full capacity (100%)
So, we have:
25% = 4.5 hours
100% = x
Cross Multiply
25% * x = 100% * 4.5 hours
Divide both sides by 25%
x = 4 * 4.5 hours
x = 18 hours
Hence, the battery at full capacity is 18 hours.
So, to answer the question, you need to check the given list of brands.
The brand closest to 18 hours answers the question

Answer:
The expected value of profit is -0.5125. This is expected loss as value is negative.
Step-by-step explanation:
We are given the following in the question:
P(winning) = 0.075
Thus,
P(Loosing) =
If we win we gain a profit of $5.50 and if we loose the lottery, we loose $1.
Thus, we can form the probability distribution in the following manner:
Event: Winning Loosing
Profit(x): +5.50 -1
P(x): 0.075 0.925
We have to calculate the expected value of the profit.
Thus, the expected value of profit is -0.5125. This is expected loss as value is negative.
I did the math and it said it was 60$
my mother has a degree in math and was top in her class
I asked her how to do it and she showed me how to, and I got 60$
sorry if its wrong
