Step-by-step explanation:
The sum of two numbers is 17 and their product is 72. Find the smaller number.
=========================================
Explanation:
Through guess and check, we find that
8+9 = 17
8*9 = 72
We see that 8 is the answer.
--------------------
Another approach:
Let m and n be the two numbers.
They sum to 17 which leads to m+n = 17. Solving for n gets us n = -m+17.
Their product is 72, so, m*n = 72
Apply substitution and we get the following:
m*n = 72
m*(-m+17) = 72
-m^2 + 17m = 72
-m^2 + 17m - 72 = 0
-1(m^2 - 17m + 72) = 0
m^2 - 17m + 72 = 0
Now apply the quadratic formula
[tex]m = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\m = \frac{-(-17)\pm\sqrt{(-17)^2-4(1)(72)}}{2(1)}\\\\m = \frac{17\pm\sqrt{1}}{2}\\\\m = \frac{17\pm1}{2}\\\\m = \frac{17+1}{2} \ \text{ or } \ m = \frac{17-1}{2}\\\\m = \frac{18}{2} \ \text{ or } \ m = \frac{16}{2}\\\\m = 9 \ \text{ or } \ m = 8\\\\[/tex]
If m = 8, then n = -m+17 = -8+17 = 9.
If m = 9, then n = 8 through similar steps.
We see the two values are 8 and 9, the smaller of which is 8.

Jaylen used the seat number for each of the 6,500 fans' seats in the stands at a college football game and put the numbers in a computer program. He randomly chose 200 numbers and found that 36 of those people had also purchased a parking voucher. Estimate the number of fans in the stands at a sold-out football game that purchased a parking voucher. Explain.
Answer:
1170 seats
Step-by-step explanation:
Given
[tex]Seats = 6500[/tex]
From the computer program, we have:
[tex]Sample = 200[/tex]
[tex]Voucher = 36[/tex]
First, we calculate the proportion (p) of those that bought the voucher
[tex]Proportion = \frac{Voucher}{Sample}[/tex]
[tex]p = \frac{36}{200}[/tex]
[tex]p = 0.18[/tex]
Using the larger population (i.e. 6500 seats), the esitimate of people that have bought the voucher is then calculated as:
[tex]Estimate= Proportion * Seats[/tex]
[tex]Estimate= 0.18 * 6500[/tex]
[tex]Estimate= 1170[/tex]

Maxine spent 15 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 120% more time doing homework this week. Is she correct? Show your work to justify your decision.
Answer:
Yes
Explanation: 120 % = 1.2
If Maxine is correct, then she spent 1.2
times the hours she did homework than last week.
15 ⋅ 1.2 = 18.0 = 18
15 hours ⋅ 1.2 = 18.0 hours = 18 hours
This means that Maxine is correct.
Your fi nancial advisor recommends buying a 10-year bond with a face value of $1,000 and an annual coupon of $80. The current interest rate is 7 percent. What might you expect to pay for the bond (aside from b
Answer:
Bond Price= $1,070.24
Step-by-step explanation:
Giving the following information:
Cupon= $80
Number of periods= 10 years
Face value= $1,000
Interest rate= 7%
To calculate the price of the bond, we need to use the following formula:
Bond Price= cupon*{[1 - (1+i)^-n] / i} + [face value/(1+i)^n]
Bond Price= 80*{[1 - (1.07^-10)] / 0.07} + [1,000 / (1.07^10)]
Bond Price= 561.89 + 508.35
Bond Price= $1,070.24
