Answer:
The probability that a randomly selected day will generate more than $6,000 in revenue is 0.325.
Step-by-step explanation:
The frequency distribution of daily revenue for an Italian restaurant in Wilmington, Delaware is:
<u>Revenue</u> <u>Frequency</u>
Under $2,000 18
$2,000 - $4,000 10
$4,000 - $6,000 26
$6,000 - $8,000 14
$8,000 - $10,000 8
Over $10,000 4
Total 80
The probability of an event <em>E</em> is defined as:
Here,
n (E) = favorable outcome
N = total outcomes
The favorable outcomes of the event <em>X</em> : "more than $6,000 in revenue" is defined as:
n (X) = 14 + 8 + 4 = 26
Total number of outcomes is, <em>N</em> = 80.
Compute the probability of the event <em>X</em> is:
Thus, the probability that a randomly selected day will generate more than $6,000 in revenue is 0.325.
Answer:
If Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.
Step-by-step explanation:
First, you have to calculate the 4% of the bill and add that amount to the total of the bill to determine the total amount including the tax:
193.75¨*4%=7.75
193.75+7.75=201.5
Now, you have to calculate 16% of the amount including the tax:
201.5*16%=32.24
According to this, the answer is that if Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.
Answer:
<u>Speed equals distance divided by time.</u>
<u>Time equals distance divided by speed.</u>
So, you use one of them... either speed or time... to solve for the other.
V = (1/3)·π·r²·h First, multiply both sides by 3:
3V = π·r²·h Now, divide by π·h
3V / (π·h) = r² Finally, take the square root of both sides:
±√[ 3V / (π·h) ] = r² If you are in algebra, you need the ±; if you are in geometry, you probably don't (usaully, you don't have negative radii).
