28 = -7/5y (cross multiply)

28*5 = -7y

140 = -7y (divide both sides by -7)

140/-7 = -7y/-7

-20 = y

y = -20

28*5 = -7y

140 = -7y (divide both sides by -7)

140/-7 = -7y/-7

-20 = y

y = -20

Show steps

**Answer:**

y=−2x+4

**Step-by-step explanation:**

Let's solve for y.

2y+4x=8

Step 1: Add -4x to both sides.

4x+2y+−4x=8+−4x

2y=−4x+8

Step 2: Divide both sides by 2.

2y/2=

(−4x+8)/2

How many sandwiches must you sell to make $100 profit

**Answer:**

About 25 sandwiches...

**Step-by-step explanation:**

**Answer:**

67 sandwiches

**Step-by-step explanation:**

If you invest 250 dollars to start, you're currently -250. If you gain 5.25 per sandwich you sell, you'd need to sell about 67 sandwiches.

I'm not entirely sure what your question meant though. If the question is simply asking how many sandwiches it would take to make 100 dollars, it would be about 20 sandwiches. If the question is asking how many sandwiches you'd need to sell to gain 100 dollars in profit, covering the cost of the cart, it would be about 67 sandwiches.

how do i find the values for mean and standard deviation

**Answer:**

1/ Mean: find the average of the numbers by add up all the numbers then divide by how many numbers there are.

2/ Standard Deviation: First, for each number: subtract the Mean and square the result. Then work out the mean of those squared differences. Take the square root of that and we are done!

Salena needs to purchase 9 skirts for a new job. her friend, Jamie goes with her each of the skirts costs $41. Salena says that she can find the total cost by multiplying 9 and 4 and adding that to product of 9 and 1. Jamie disagrees and says that she needs to find the product of 9 and 40 and add that to the product of 9 and 1. Who is correct and why?

**Answer:**

Jamie is correct. This is because 41 is a combination of 40 and 1. Salena thinks that the 4 is just a 4, however, the 4 is in the tens place, so the 41 without the 1 is 40. The answer to this 41 times 9 is 369. Not 45.

**Step-by-step explanation:**

Each skirt is $41

Salena needs 9

(9*40) + (9*1)

360 + 9

$369

A television costs $400 to purchase. Renting the same telension

requires making a $50 non-refundable deposit plus monthly payments of

$25. After how many months will the cost to rent the television equal the

cost to purchase it

**Answer:**

14 months

**Step-by-step explanation:**

400 dollars to purchase tv

50 dollars down already in renting television

400-50=350 dollars

350 dollars/ 25 dollars each month for television=14 months

1 year 2 months

Hope this helps!

The **number** of months will the **cost** to rent the television equal the cost to **purchase** it is **1 year 2 months**.

Given that, a television costs=$400. Renting the same television requires making a $50 non-refundable deposit plus monthly payments of $25.

What is the unitary method?The **unitary method** is a technique for solving a problem by first finding the **value** of a **single unit**, and then finding the **necessary value** by **multiplying** the single unit value.

Now, 400 dollars to purchase a television.

50 dollars down already in renting television

400-50=350 dollars

Number of months=350/25 =14 months

Therefore, the **number** of months will the **cost** to rent the television equal the cost to **purchase** it is **1 year 2 months**.

You come from a large, dysfunctional family. You learn of this year’s upcoming reunion, and dread the very thought of being around those people for any length of time. However, you’ve been intrigued by your introductory statistics course, and decide you will have some fun with the reunion by using it as an opportunity to study your family. As a preliminary project, you want to keep track of how many times each family member verbally assaults another person throughout the first 24 hours.

After 24 hours, you review your notes:

Find the mean, median, and mode of your distribution:

1. Mean

2. Median

3. Mode

4. Which measure of central tendency do you think is most appropriate for this dataser? Why?

5. What is the range of your dataset? Show how you figured it out.

6. Define, as specifically as necessary, the population in which you are interested for this research. In other words, how do you decide whether a person would be appropriate to include in your study?

7-9. Find the standard deviation for the data in the table on the first page. Showing your work is how you earn points for this part

10. What is the standard deviation of your dataset?

**Answer:**

Explained below.

**Step-by-step explanation:**

The data provided is for the number of times each family member verbally assaults another person throughout the first 24 hours.

Use Minitab to compute the descriptive statistics.

Go to Stat → Basic Statistics → Display Basic Statistics

A dialog box will open.

Select the variable.

Select 'Statistics'.

Another dialog box will open.

Select the statistics required.

Press OK.

Select "Graphs'.

Select Histogram.

Press OK

The output is attached below.

(**1**)

The mean of the data is, **Mean = 10**.

(**2**)

The median of the data is, **Median = 8.50**.

(**3**)

The mode of the data is, **Mode = 5**.

(**4**)

The inequality statement for the mean, median and mode is:

Mean > Median > Mode

A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the histogram of the distribution.

Also if the Mean > Median > Mode then the distribution is skewed to the right.

For a skewed distribution the best of central tendency is the **median**.

So, the measure of central tendency that is most appropriate for this dataset is, **Median**** = 8.50**.

(**5**)

The range of the data set is:

Range = Maximum - Minimum

= 19 - 4

= 15

Thus, the range is **15**.

(**6**)

The population of interest is the number of times the family members verbally assaults another person throughout the first 24 hours.

(**7**)

Consider the Minitab output.

The standard deviation of the data set is, **SD**** = 5.60**.

A line has a slope of 9 what is the slope of a line it is perpendicular to this line? *

9

-9

1/9

-1/9

**Answer: **-1/9

**Explanation: **Perpendicular lines have *negative* reciprocal slopes.

A negative reciprocal slope is a fancy way of

saying flip the fraction and change the sign.

Notice that our slope is an integer.

We can turn it into a fraction by putting it over 1.

So we have 9/1.

A line perpendicular to this would be a negative reciprocal.

So flip the fraction, giving us 1/9, and change the sign to get -1/9.

Suppose you scored an 80 on a measure where the mean is 65 and the standard deviation is 5. How many standard deviations from the mean is your score

Answer:

The score is 3 standard deviations from the mean

Step-by-step explanation:

To find this, we simply calculate the z-score

Mathematically;

z-score = (x-mean)/SD

In this question , x = 80

mean = 65

SD = 5

Thus;

z-score = (80-65)/5 = 15/5 = 3

Question 3

20 pts

The Indians won 14 out their last 20 games. What percent of their games

did they win?

**Answer:**

They won 70% of their games.

**Step-by-step explanation:**

Convert your fraction to a percentage.

Divide 14 by 20, which gets you 0.70.

Then multiply it by 100, which gives you 70.

Now you have a fraction of 70/100.

That's how you get 70%

First write the two numbers as a ratio, 14:20. We know that percent means out of 100, and we also know that 20 is a factor of 100, so let’s divide those numbers. We get 5 * 20 is equal to 100, then we multiply the other side of the ratio(14) by five. At last we get 70:100, which is nothing but 70%. To check multiply 70/100 by 20, and if you get 14 as the product, then we are correct.

Find the value of x for which line a is parallel to line b .

**Answer:**

x = 20

**Step-by-step explanation:**

For a and b to be parallel, they must both add up to 180. Therefore, we can set up an equation:

3x+6x = 180

9x = 180

x = 20

Answer: X=20

Step-by-step explanation: Angle 4 and angle 5 are same side interior angles which means they are supplementary(180) and 3x+6x=180 would simplify to 9x=180 and by dividing 180/9 you get x=20.

How do you find what p is?

**Answer:**

p > -3

**Step-by-step explanation:**

This is an alternating p-series. It is absolutely convergent if│an│converges. 1 / nᵖ⁺³ converges if the exponent is greater than 1.

p + 3 > 1

p > -2

The series is conditionally convergent if │an│diverges. 1 / nᵖ⁺³ diverges if the exponent is greater than 0 and less than or equal to 1.

0 < p + 3 ≤ 1

-3 < p ≤ -2

Combining these two, we get p > -3.
