Answer:
$84.80
Step-by-step explanation:
find the difference between accurate price and written price: 74 - 47 = 27
find written total (before Mrs. Taylor found mistake) by undoing the mean calculation: 82.55 x 12 = $990.60
the total expenses is $27 more than what they thought: 990.60 + 27 = 1017.60
divide accurate total by 12 to find mean: 1017.60 / 12 = $84.80
hope this helps :)
i dont know sorry, maybe someone else can help you?
Answer:
5 cents
Step-by-step explanation:
So the roulette wheel would have a total of 38 numbers, which means 38 different possible cases. Since you are allowed to bet on 5 numbers, the chance to win this is 5 out of 38 and to lose this is 33 out of 38.
If you win, you get 1 + 6 = 7 dollar, and if you lose, you lose 1 dollar.
Therefore the expected amount out of this game is:

or 5 cents
To rearrange the equation given, we need to take note the rules in adding, subtracting, multiplying and dividing terms. We rearrange the equation as follows:
<span>((a+b/c)(d-e)=f) 1/(d-e)
</span>(a+b/c = f/(d-e))c
a+b = fc/(d-e)
a = [fc/(d-e)] - b
Hope this answers the question.
