Answer:
The number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.
Step-by-step explanation:
Consider the provided information.
A football costs $35, a basketball costs $25 and a volleyball costs $15.
Let F represents the football, B represents the basketball and V represents the volleyball.
On a given day, the store sold 5 times as many footballs as volleyballs.
......(1)
They brought in a total of $3750 that day,
......(2)
The money made from basketballs alone was 4 times the money.
......(3)
By equation 1, 2 and 3.



Substitute the value of V in equation 1 and 3.


Hence, the number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.
T= total cost
n= number of days
Total cost equals the cost per day times the number of days plus the fee.
T= $39n + $65
substitute 5 for n
T= 39(5) + 65
T= 195 + 65
T= $260 total cost
Hope this helps! :)

Answer:
0.67% probability he will have to shut down after this month
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
On average sells 8.9 machines per month.
So 
Using the Poisson distribution, what is the probability he will have to shut down after this month
If he sells less than 3 machines.






0.67% probability he will have to shut down after this month
