A manager at a gas station realized that there appeared to be a quadratic relationship between the price he charged for a doughnut and the number he sold for the day.
Using a quadratic regression model base on the data, how many doughnuts would be predicted to sold if he charges $0.85 for a doughnut?
Answer choice:
a) ≈22
b) ≈25
c) ≈29
d) ≈30
Answers
He sold 28 at 0.75 cents and sold 21 at 0.99 cents.
0.85 is between 0.75 and 0.99 so he sells between 21 and 28 donuts.
0.85 is closer to 0.75 ,so the number should be closer to28.
The answer should be b)25

A new car is purchased for \$18,000$18,000 and over time its value depreciates by one half every 3.5 years. How long, to the nearest tenth of a year, would it take for the value of the car to be \$900$900?
Answers
Answer:
15.1
Step-by-step explanation:
Rounding equation up to the nearest hundred dollars, the car's value 19 years later will be around $2,500.
What is equation?In mathematics, an equation is a statement stating the equality or two expressions. An equation consists of two sides split by an algebraic equation (=). For illustration, the argument "2x + 3 = 9" argues that the statement "2x + 3" is equal to the value "9".
Given that new car is purchased for $18,000 and over time its value depreciates by one half every 3.5 years Because the car depreciates by half every six years, the car's value after t years is provided by:
To determine the worth of the car 19 years after purchase, we have to analyse V(19):
y = 2000
y = a(1/2) ^t/h
q = 18000
h= 3.5
t=19
Therefore,
y = 18,000
y=2,500.52211582
y≈2,500
Thus the car's value 19 years later is around $2,500.

Answer:
10.8 hours
Step-by-step explanation:
Mr. Chandler has a head start of ...
(4.5 h)(60 mi/h) = 270 mi
Mrs. Chandler is closing the gap at the rate of ...
(85 mph) -(60 mph) = 25 mph
At that rate, she will close the 270 mile gap in ...
(270 mi)/(25 mi/h) = 10.8 h
It will take Mrs. Chandler 10.8 hours to catch up.

Susan invests $Z at the end of each year for seven years at an annual effective interest rate of 5%. The interest credited at the end of each year is reinvested at an annual effective rate of 6%. The accumulated value at the end of seven years is $X. Lori invests $Z at the end of each year for 14 years at an annual effective interest rate of 2.5%. The interest credited at the end of each year is reinvested at an annual effective rate of 3%. The accumulated value at the end of 14 years is $Y.
Required:
Calculate Y/X.
Answers
Answer:
2.02955
Step-by-step explanation:
Given that:
Susan invests $Z as each year ends for seven years.
So we assume that Z = 1
Susan's accrued value comprises $7 invested each year at a 6 percent annual effective rate.
The cashflow interest:
The cashflow of Susan interest payments are:
Payments Time
0 1
0.05 2
2(0.05) 3
3(0.05) 4
4(0.05) 5
5(0.05) 6
6(0.05) 7
The accumulated value of this cash flow is:
[tex](0.05)I_{6\%} = (0.05) \dfrac{((1+0.06)_{6\%} - 6)}{0.06} \\ \\ \implies 1.1653[/tex]
So Susan accumulated values is:
X = 7 + 1.1653
X = 8.1653
Lori's accumulated value is $14, which she has set aside to plan her cash flow for interest.
The cashflow of Lori interest payments are;
Payments 0 0.025 2(0.025) 3(0.025) ......... 13(0.025)
Time 1 2 3 4 .......... 14
The accumulated value of cash flow is:
[tex](0.025 )(I)_{3\%} =(0.025) \dfrac{(1+0.03)_{3\%}-13}{0.03}\\ \\= 2.5719[/tex]
Now, Lori's accumulated value is:
Y = 14 + 2.5719
Y = 16.5719
Since; Susan value X = 8.1653
Lori's value Y = 16.5719
∴
[tex]\dfrac{Y}{X}= \dfrac{16.5719}{8.1653}[/tex]
= 2.02955
