Answer:

110 + 25x = Total Cost (or any type of variable needed, like a,b,c, etc.)

Step-by-step explanation:

Since the monthly fee occurs more than once, and we don't have the number of months, we put an x to represent the amount of months. The $110 is the one time additional fee for the membership, so it doesn't need a variable.

The store has a base cost of  

$

1800

, the cost per pair of shoes is  

$

25

. Each pair of shoes is sold for  

$

65

, therefore the profit per pair of shoes is

$

65

−

$

25

=

Find the length and width of a rectangle that has the given perimeter and a maximum area. perimeter: 244 meters
MissTica
We know that

[perimeter of rectangle]=2*(<span>length+width)
</span>
Let
x-----------> length
y-----------> width
so
P=2*(x+y)-----------> 244=2*(x+y)-----> x+y=122-------> y=122-x

Area=x*y-------> x*(122-x)----> 122x-x²

find the derivative function and equals to zero

122-2x=0-----> 122=2x----------> x=61 m
y=122-x------> y=122-61---------> y=61 m

<span>the maximum area is given by a square
</span>
the answer is
is a square of side 61 m

If there 8 boys for every 7 girls with 195 total, how many are boys?
Lilit [14]
B = boys   g = girls
.................................

b + g = 195        b = 195 - g

<u>b</u> = <u>8</u>
g    7

Substitute b for 195 - g in the 2nd equation:

<u>b</u> = <u>8</u>
g    7

<u>195 - g</u> = <u>8</u>
    g        7

Cross Multiply

8g = 7 . ( 195 - g )
8g = 1365 - 7g
8g + 7g = 1365
15g = 1365
g = <u>1365</u>
        15
g = 91

Substitute g for 91 in one of the equations:

b + g = 195
b + 91 = 195
b = 195 - 91
b = 104


S = 104 boys.

An automotive service center would like feedback on its customer service. each customer receives a printed card after they pay f
My name is Ann [436]

The statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.

<h3>What is a survey?</h3>

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

We have an automotive service centre would like feedback on its customer service each customer receives a printed card after they pay for services with a short survey on which customer service is ranked on a scale from 1  to 5.

From the data given we can say, not everyone will choose to leave a review when leaving the store, and those who do will have been inconvenienced in some way and felt compelled to do so, while the rest of the customers left and went about their business.

Thus, the statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.
