bentonville high school’s student council is planning a fundraiser. a local coffee shop has agreed to make a flag donation of $500 and also give a percent of their total sales over a specified weekend. the total donation can be modeled by the function rule D(s)=500+0.05s, where s represents the total sales at the coffee shop during the fundraising weekend in dollars. find the value of D(2750), showing your work. What does this quantity mean in the context of the problem solution
Answer: D(2750) = 637.5
if total sales = $2750 then total donation = $637.5
Step-by-step explanation:
GIven: A local coffee shop has made a flat donation of $500 and also give a percent of their total sales over a specified weekend.
The total donation can be modeled by the function rule D(s)=500+0.05s,
where s = total sales at the coffee shop during the fundraising weekend in dollars.
Now, D(2750) = 500+0.05(2750)
= 500+ 137.5
= 637.5
i.e. if total sales = $2750 then total donation = $637.5

A water hose discharges water at a rate of 45 gallons per minute. Which graph has a slope
that best represents this rate?
Answer:
F
Step-by-step explanation:
F is the correct graph because the bottom is for minutes and if you drag your finger on the 1 minute you meet 45 which is how many gallon per minute. and if you go to 2 minutes you meet with 90 which is 45+45=90 and 45 is one minute and 90 is 2 minutes.
srry if that was complicated
Hope this helps you!
The graph which best represents the rate of discharge given is graph F.
It is given that discharge rate of a water hose is 45 gallons per minute.
We have to check which graph has a slope that best represents this rate.
What do you mean by discharge rate of water ?
Discharge rate of water is defined as the rate at which drainage water is released from a site.
As per the question ;
The rate of discharge = 45 gallons per minute
So,
We can say that ;
When x = 1 minute
y = 45 gallons
We can conclude that F is the correct graph because the x-axis is for minutes and if you check at time 1 minute you get 45 gallons at the y-axis which shows the no. of gallons per minute.
Thus , the graph which best represents the rate of discharge given is graph F.

It is estimated that the distance traveled by each volunteer driver at the Huntington VA Medical Center is normally distributed with a mean of 50 thousand miles and a standard deviation of 12 thousand miles each year. What percentage of drivers can be expected to travel either below 30 or above 60 thousand miles in a year?
Answer: 25.08%
Step-by-step explanation:
Given: Distance traveled by each volunteer driver is normally distributed.
Mean ([tex]\mu[/tex]) = 50 thousand miles
standard deviation ([tex]\sigma[/tex])= 12 thousand miles
Let X = distance traveled by each volunteer driver
Required probability : [tex]P(X<30)+P(X>60)[/tex]
[tex]=P(\dfrac{X-\mu}{\sigma}<\dfrac{30-50}{12})+P(\dfrac{X-\mu}{\sigma}>\dfrac{60-50}{12})\\\\=P(z<-1.67)+P(z>0.83)\ \ \ [z=\dfrac{X-\mu}{\sigma}]\\\\= (1-P(z<1.67))+(1-P(z<0.83)\ \ \ [P(Z<-z)=1-P(Z<z)=P(Z>z)]\\\\= 2- P(z<1.67)-P(z<0.83)\\\\= 2- 0.9525-0.7967=0.2508\ \ [\text{By p-value table}][/tex]
Hence, percentage of drivers can be expected to travel either below 30 or above 60 thousand miles in a year = 25.08%

Evaluate (18)^2-(15)^2
Please show working.
Answer:
99
Step-by-step explanation:
You can solve it by Squaring/multiply 18 by itself and 15 by itself then subtract them both:
(18 × 18) - (15 × 15)
324 - 225
99
You could also do difference of two squares:
(x² - y²)
= (x + y) (x - y)
= (18 + 15) (18 - 15)
= (33) (3)
= 99
Answer:
99Step-by-step explanation:
Evaluate
= (18)^2-(15)^2
