Answer:

A = $3.2

B = $0.2

C = $0.8

Step-by-step explanation:

First of all, convert the mixed fraction to improper fraction

2¾ pounds = 11/4 pounds

He bought 11 / 4 pounds for $8.80

11 / 4 pounds = $8.80

1 pounds = $x

X = [8.80 / (11/4)]

X = (8.8 * 4 ) / 11

X = $3.2

1 pounds cost $3.2

B.

1 pounds = 16 ounces

But 1 pounds cost $3.2

16 ounces = $3.2

1 ounces = $y

y = (1 * 3.2) / 16

y = $0.2

1 ounce costs $0.2

C.

The unit price of 1 ounce = $0.2

4 ounce = $z

Z = 4 * 0.2

Z = $0.8

The price of 4 ounces = $0.8

Considering that the data has no outliers, the mean of 3.2 inches should be used to describe the center of the data represented in this line plot.

<h3>What measure should be used to describe the center of a data-set?</h3>

It depends if the data-set has outliers or not.

  • If it does not have outliers, the mean should be used.
  • If it has, the median should be used.

The dot plot gives the number of times each measure appears. Since there is no outliers, that is, all values are close, the mean should be used. It is given by:

M = (2 x 1 + 3 x 2 + 2 x 3 + 1 x 5 + 1 x 6 + 1 x 7)/(2 + 3 + 2 + 1 + 1 + 1) = 3.2 inches.

The mean of 3.2 inches should be used to describe the center of the data represented in this line plot.

Worth 33 points each!!

Where <em>x </em>is the number of books sold, <em>i </em>is income, and <em>c </em>is cost:

<em>c = 4x + 3500 </em> ($4 per book plus the 3500 flat marketing fee)

<em>i = 15x </em>($15 per book)

You are looking for the point where these intersect: the intersection is where the income is equal to the cost, and at any point after that the income is greater than the cost. So, set the equations equal to each other:

<em>4x + 3500 = 15x     </em>

subtract 4x from both sides

<em>3500 = 11x</em>              

divide both sides by 11

<em>x = 318.181818</em>

So, you would have to sell a minimum of 319 books in order to make a profit.
