When you are comparing two sets of data, and one set is strongly skewed and the other is symmetric, which measures of the center and variation should you choose for the comparison?

Answers

Answer 1

Given that one set of data is symmetric while the other one is strongly skewed, the most appropriate measure of the center is median. Median is the value of the data which is at the center. This means that half of data are less than the median while half are greater than.

The variation can however be measured through the use of Quartiles method in order for our data to be equally divided into four equal group that allows us to determine how the data are spread out.

Answer 2

When comparing two sets of data, choose the median for skewed data and mean with standard deviation for symmetric data.

When comparing two sets of data where one is strongly skewed and the other is symmetric, for the comparison, it is advisable to choose the median as the measure of the center for the skewed data since it is resistant to outliers, and the mean and standard deviation for the symmetric data to give an overall representation of the data.

Brooke buys a toothbrush and toothpaste for 2.95. If the toothbrush costs .65 less than the toothpaste. How much is the toothbrush

Answers

Divide the cost by 2 and then add .65 to one side and subtract it from one of side and add it to the other. .82 for the tooth brush and 2.12 for the toothpaste

Final answer:

Given the information, we can determine that the cost of the toothbrush is $1.15. To arrive at this, we created an equation based on the given information and solved for the unknown, which in this case is the cost of the toothbrush.

Explanation:

If Brooke buys a toothbrush and toothpaste for $2.95, and the toothbrush costs $.65 less than the toothpaste, we have to use the information to solve for the cost of the toothbrush.

Let's define the cost of the toothpaste as x. Therefore, the cost of the toothbrush would be x - $0.65 (since the toothbrush costs $0.65 less than the toothpaste).

The combined cost of the toothbrush and toothpaste is $2.95, so we can set up the equation: x + (x - $0.65) = $2.95

If we simplify and solve this equation, we get x = $1.80. That's the cost of the toothpaste. The cost of the toothbrush would therefore be $1.80 - $0.65 = $1.15.

So, the toothbrush costs $1.15.

Did I do number 2 right?

Answers

You should have
y = a*(x-p)*(x-q)
2 = a*(x-0)*(x-1)
2 = a*(2-0)*(2-1)
2 = a*(2)*(1)
2 = 2a
2a = 2
2a/2 = 2/2
a = 1

So the equation
y = a(x-0)(x-1)
updates to
y = 1(x-0)(x-1)
and that simplifies to
y = x(x-1)

The next step is to distribute the x through to get this final answer
y = x^2-x

Rhinestone Cowboy Dreadlock Holiday MacArthur Park Total

Republican B 33 C 90

Democrat A 24 34 E

Total 61 D 53 171

From the table, we have the following equations

[tex]B + 33 + C = 90[/tex]

[tex]A + 24 + 34 = E[/tex]

[tex]61 + D + 53 = 171[/tex]

The above equations become:

[tex]B + 33 + C = 90[/tex]

[tex]B + C = 57[/tex]

[tex]A + 24 + 34 = E[/tex]

[tex]A + 58 = E[/tex]

[tex]61 + D + 53 = 171[/tex]

[tex]D= 57[/tex]

Also from the table, we have the following equations

[tex]B + A = 61[/tex]

[tex]C + 34 = 53[/tex]

[tex]90 + E = 171[/tex]

Solve for C and E in the above equations

[tex]C + 34 = 53[/tex]

[tex]C = 19[/tex]

[tex]90 + E = 171[/tex]

[tex]E = 81[/tex]

Recall that:

[tex]A + 58 = E[/tex]

So, we have:

[tex]A + 58 = 81[/tex]

[tex]A = 23[/tex]

Recall that:

[tex]B + A = 61[/tex]

So, we have:

[tex]B + 23 = 61[/tex]

[tex]B = 38[/tex]

Hence, the values that can be determined from the table are:

A = 23, B = 38, C = 19, D = 57 and E = 81

Nonstandard dice can produce interesting distributions of outcomes. you have two balanced, six-sided dice. one is a standard die, with faces having 1, 2, 3, 4, 5, and 6 spots. the other die has three faces with 0 spots and three faces with 6 spots. what are the possible values for the total number of spots y on the up-faces when you roll these two dice?

Answers

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

One die can show the values 1-6, while the other die can only show 0 or 6. So the possible totals are 1 through 6 plus 0 and 1 through 6 plus 6. Written out, one-by-one, this gives: 1+0 = 1 2+0 = 2 3+0 = 3 4+0 = 4 5+0 = 5 6+0 = 6 1+6 = 7 2+6 = 8 3+6 = 9 4+6 = 10 5+6 = 11 6+6 = 12

Final answer:

When rolling a standard die and another die with faces having either 0 or 6 spots, the possible total values y range from 1 to 12, excluding the numbers 5 and 6 twice due to the unique nature of the second die.

Explanation:

The question asks about the possible values for the total number of spots y on the up-faces when you roll two nonstandard dice: a standard six-sided die with faces having 1, 2, 3, 4, 5, and 6 spots, and another die with three faces having 0 spots and three faces having 6 spots. To find y, we need to consider all the possible outcomes of rolling these two dice and summing the numbers of spots on the up-faces.

If the standard die shows a 1, y can be 1+0=1 or 1+6=7.If it shows a 2, y can be 2+0=2 or 2+6=8.If it shows a 3, y can be 3+0=3 or 3+6=9.If it shows a 4, y can be 4+0=4 or 4+6=10.If it shows a 5, y can be 5+0=5 or 5+6=11.If it shows a 6, y can be 6+0=6 or 6+6=12.

Therefore, the possible values for y are 1, 2, 3, 4, 5, 5, 7, 8, 9, 10, 11, and 12.

Answers

The equation of a horizontal line passing through the point (−3, 8) is y= 8

How to determine the equation of a horizontal line passing through the point (−3, 8)

From the question, we have the following parameters that can be used in our computation:

The point (−3, 8)

The equation of a horizontal line is of the form

y = c, where

c is a constant.

Since the line is horizontal, the value of y is constant for all points on the line.

In this case, the line passes through the point (−3,8), so the equation of the horizontal line is y = 8.

[tex]f(x)=3x+2\\\\g(x)=x^2+1.[/tex]

We are to find the expression equivalent to [tex](f*g)(x).[/tex]

We know that

for any two functions p(x) and q(x), we have

[tex](p*q)(x)=p(x)\times q(x).[/tex]

Therefore, we get

[tex](f*g)(x)\\\\=f(x)\times g(x)\\\\=(3x+2)(x^2+1)\\\\=x^2(3x+2)+1(3x+2)\\\\=3x^3+2x^2+3x+2.[/tex]

Thus, the required expression is [tex]3x^3+2x^2+3x+2.[/tex]

the table shows the annual profits (in thousands of dollars) of a county fair from 2008 to 2012. What must the 2012 profit be (in hundreds of dollars) to break even over the five-year period?

Answers

The break-even point is the point in which a business makes no gain and no loss.

Let the 2012 profit be x, then

2.5 + 1.75 + (-3.3) + (-1.4) + x = 0

4.25 - 3.3 - 1.4 + x = 0

-0.45 + x = 0

x = 0.45

Therefore, the 2012 profit must be 0.45 thousand dollars = 4.5 hundred dollars to break even over the five-year period.

The 2012 profit must be 0.45 thousand dollars is equal to 4.5 hundred dollars to break even over the five-year period.
