A business class surveyed college students about the cost (in dollars) of their most recent haircuts. The resulting data is summ

arized in the table below. Which data representations can you make using the information above? Select all that apply
Question 1 options:

histograms

box plots

dot plots

2. Which of the following statistics could you find given the information above (see question #1)? Select all that apply.

Question 2 options:

range

mode

standard deviation

interquartile range

3. What does the data above (see question #1) tell you about the difference in haircut costs between women and men? You may want to discuss similarities or differences in the shape, center, and spread of the data. Explain your reasoning and give mathematical evidence to support any claim that you make. If you draw any charts (or create them online) you may insert the image or add a file to your response.

4. For both women and men, the mean cost is greater than the median cost. Why do you think the data has this result? Explain your reasoning.

5. Is the mean or the median a better measure of center for the data in the table? In other words, would you fill in the blanks of this sentence with the mean values or the median values?

"The data shows that women typically spend about ____ on haircuts, and men typically spend about ____ on haircuts."

Explain the reasoning behind your choice.

<h3>Answer:</h3>

System

  • p + m = 10
  • 0.8m = 0.4·10

Solution

  • p = m = 5 — 5 lb peanuts and 5 lb mixture
<h3>Step-by-step explanation:</h3>

(a) Generally, the equations of interest are one that models the total amount of mixture, and one that models the amount of one of the constituents (or the ratio of constituents). Here, there are two constituents and we are given the desired ratio, so three different equations are possible describing the constituents of the mix.

For the total amount of mix:

... p + m = 10

For the quantity of peanuts in the mix:

... p + 0.2m = 0.6·10

For the quantity of almonds in the mix:

... 0.8m = 0.4·10

For the ratio of peanuts to almonds:

... (p +0.2m)/(0.8m) = 0.60/0.40

Any two (2) of these four (4) equations will serve as a system of equations that can be used to solve for the desired quantities. I like the third one because it is a "one-step" equation.

So, your system of equations could be ...

  • p + m = 10
  • 0.8m = 0.4·10

___

(b) Dividing the second equation by 0.8 gives

... m = 5

Using the first equation to find p, we have ...

... p + 5 = 10

... p = 5

5 lb of peanuts and 5 lb of mixture are required.

7-ounce package costs $2.59. A 12 ounce package costs $4.56. An 18 ounce package costs $6.30. Which package is the best buy?
Yanka [14]

Answer:

18 ounce package for $6.30

Step-by-step explanation:

For each one, you divide the money by the package to see how much it is per ounce.

2.59 / 7 = $0.37 per oz

4.56 / 12 = $0.38 per oz

6.30 / 18 = $0.35 per oz
