Offered coupon Not offered coupon Returned to store 85 60 Did not return to store 25 38 Select a word or phrase from the drop-down menus to correctly complete the statements describing the association. More customers who returned to the store were Choose... . More customers who did not return to the store were Choose... . There Choose... appear to be an association between whether a customer received a coupon and the customer’s tendency to return to the store to shop again.
Answer:
More customers who returned to the store were "Offered a Coupon"
More customers who did not return to the store were "not offered a coupon"
There "does" appear to be an association between whether a customer received a coupon and the customer’s tendency to return to the store to shop again.

Find the length of side x in simplest radical form with a rational denominator.
Answer:
[tex] x = 6\sqrt{2}[/tex]
Step-by-step explanation:
Reference angle = 45°
Adjacent side = 6
Hypotenuse = x
Applying trigonometric ratio, we have:
[tex] cos(45) = \frac{6}{x} [/tex]
Multiply both sides by x
[tex] x*cos(45) = 6 [/tex]
Divide both sides by cos(45)
[tex] x = \frac{6}{cos(45)} [/tex]
[tex] x = \frac{6}{\frac{\sqrt{2}}{2} [/tex] (cos 45 = √2/2)
[tex] x = \frac{6}*{\frac{2}{\sqrt{2}} [/tex]
[tex] x = \frac{12}{\sqrt{2}} [/tex]
Rationalize
[tex] x = \frac{12*\sqrt{2}}{\sqrt{2}*\sqrt{2} [/tex]
[tex] x = \frac{12*\sqrt{2}}{2} [/tex]
[tex] x = \frac{6*\sqrt{2}}{1} [/tex]
[tex] x = 6\sqrt{2}[/tex]

An online shopping club has 10,000 members when it charges $7 per month for membership. For each $1 monthly
increase in membership fee, the club loses approximately 400 of its existing members. Write and simplify a function
R to represent the monthly revenue received by the club when x represents the price increase.
Answer:
The function that can be used in the online shopping club about its monthly revenue is:
[tex]R = -400x^{2} +7200x+70000[/tex]
Step-by-step explanation:
First, we're gonna take into account the different values we have in the exercise:
10,000 members$7 per month for membershipLoses of 400 members by each $1 monthly increaseHow the variable [tex]x[/tex] represents the price increase, we can do the formula below:
[tex](10000 - 400x) * (7+x)[/tex]In this formula, we represent in the first part that by each 1 in the variable [tex]x[/tex], the total of members will be reduced in 400, in the second part, we mention that at the same time, the membership fee will be increased in the same value of [tex]x[/tex]. Now we must simplify this function:
[tex](10000 - 400x) * (7+x)[/tex]We operate the values:
[tex]70000+10000x-2800x-400x^{2}[/tex]Solve we can:
[tex]70000+7200x-400x^{2}[/tex]And organize:
[tex]-400x^{2} +7200x+70000[/tex]At the end, how [tex]R[/tex] represents the monthly revenue received by the club, we use that variable for our formula:
[tex]R=-400x^{2} +7200x+70000[/tex]the graph shows the voltage in a circuit changing as temperature increases from 100° to 600°. which is the best estimate for the rate of change of the voltage over the interval?
1.5 volts
3 5 volts
5.5 volts
7.5 volts
Answer:
3.5?
Step-by-step explanation:
The best estimate for the rate of change of the voltage over the interval will be 3.5 volts. Then the correct option is B.
What is the average rate change of a function?It is the average amount by which the function is modified per unit throughout that time period. It is calculated using the gradient of the line linking the interval's ends on the graph that represents the function. The average rate of change of the function is given as,
Average rate = [f(x₂) - f(x₁)] / [x₂ - x₁]
The graph shows the voltage in a circuit changing as temperature increases from 100° to 600°.
We know that v = 1750 at t = 600° and v = 0 at t = 100°. Then the Average rate of change is given as,
Average rate = (1750 - 0) / (600 - 100)
Average rate = 1750 / 500
Average rate = 3.5
The best estimate for the rate of change of the voltage over the interval will be 3.5 volts. Then the correct option is B.
More about the average rate change of a function link is given below.

First is to look at what sides you have in which you have the legs. This means you can use tangent. how ever you need to use arctangent or
tan^-1 to find the angle.
the way you set this up in your calculator is tan^-1(8.4÷15.2). plus be sure it's on Deg not Rad.
This leaves the answer if 28.9°

A. (1, 2)
B. (2,1)
C. (3/5,1)
D. (2,3)
Answer:
B. (2,1)
Step-by-step explanation:
Substitute the first value from the parentheses for x, and the second value for y in the equation.
Calculate.
If the answer is true, the point is a solution on the line.
3(2) -5(1) = 1
6 –5 = 1
1 = 1. True. point B is a solution on the line.
D* for example:
3(2) -5(3) = 1
6 - 15 = 1
–9 = 1 False. This is not a solution on the line.
You get the idea. The others are also false.

Complete question :
Sam knows that his MP3 player has 40% of its battery life left and that the battery
charges by an additional 12 percentage points every 15 minutes. What percent of
the mp3's battery will be charged when Sam and his family leave? If mp3 was plugged in an hour before his family plan to leave.
Answer:
88%
Step-by-step explanation:
Time before leaving = 1hour
Current percentage = 40%
Charge rate = 12% every 15 minutes
Therefore,
Charge rate per minute :
12% / 15 = 0.8% per minute
Charge recieved after one hour (60 minutes) :
0.8% * 60
= 48%
Therefore, total charge after just before leaving is:
Current percentage + percentage received
40% + 48%
= 88%
