Error Analysis: A store is instructed by corporate headquarters to put a markup of 67​% on all items. An item costing ​$6 is displayed by the store manager at a selling price of ​$4. As an​ employee, you notice that this selling price is incorrect. Find the correct selling price. What was the​ manager's likely​ error?

Part 1: The correct selling price is ​(Round to the nearest dollar as​ needed.)
Part 2: What was the​ manager's likely​ error?

A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.

Answers

Answer:

To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.

Therefore, the correct selling price is $4.

The manager's likely error was that they set the selling price at the cost (option C).

Step-by-step explanation:

The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Cost of item = $6

Markup = 67%

67% of $6 ⇒ 0.67 x 6 = $4.02

Add the markup in the cost = $6 + $4.02 = $10.02

Round to nearest dollars = $10.2 ≈ $10.

The manager put $4 which is a markup instant of the selling price of $10.

Hence "The correct selling price is $10 and the manager set the selling price at the markup".

The opposite of an angle around a point is always the same, so we know the unlabelled angle is also worth 43. Then, do 43 + 43 which is 86. Next, note that angles around a point all add up to 360. What we need to do is find the total of c and b, which is 360 - 86. Therefore, 274 is the total of b and c. Finally, half 274 to find both individual values. That means b = 137 and c = 137

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Part A: To calculate the measures of center, we can find the median and the mean for each school.

For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.

To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.

For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.

To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):

18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.

Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.

The measures of center for Seaside School are: median = 15, mean ≈ 15.9.

Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.

For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.

To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.

For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.

To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.

Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.

The measures of variability for Seaside School are: range = 15, IQR = 6.

Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

Answers

Answer:

Step-by-step explanation:

114-3

Answer:

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.

In other words you get the basic idea, you can also just count, but whatever.

Gabrielle and Rob earn a total of $2,560 this week. With their total earnings from the week, Gabrielle buys 2 train tickets that cost $215.80 each, and Rob buys 2 suitcases that cost $36.50 each. Which statement is true?

A) Gabrielle and Rob have $ 2,055.40 of the $2 ,560 left because 2,560 − 2( 215.80 ) − 2(36.50 ) is equal to 2,055.4.

B)Gabrielle and Rob have $2,091.90 of the $2,560 left because 2,560−2(215.80)−36.50 is equal to 2,091.9.

C)Gabrielle and Rob have $2,271.20 of the $2,560 left because 2,560−215.80−2(36.50) is equal to 2,271.2.

D)Gabrielle and Rob have $2,307.70 of the $2,560 left because 2,560−215.80−36.50 is equal to 2,307.7.

Answers

Answer:

A

Step-by-step explanation:

215.80 + 215.80 = 431.60

36.50 + 36.50  = 73

431.60 + 73 = 504.60

2560 - 504.60 = 2055.40

The correct statement is:

Gabrielle and Rob have $2,055.40 of the $2,560 left because 2,560 − 2(215.80) − 2(36.50) is equal to 2,055.4.

Option A is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Gabrielle and Rob's total earnings for the week are $2,560.

If Gabrielle buys 2 train tickets that cost $215.80 each.

She spends a total of:

\$431.60 (2 x 215.80).

If Rob buys 2 suitcases that cost $36.50 each, he spends a total of:

$73 (2 x 36.50).

To find out how much money they have left, we need to subtract the amount spent on tickets and suitcases from their total earnings:

$2,560 - $431.60 - $73

= $2,055.40

Therefore,

The correct statement is:

Gabrielle and Rob have $2,055.40 of the $2,560 left because 2,560 − 2(215.80) − 2(36.50) is equal to 2,055.4.

sorry but... I HAVE AN OTHER SLOPE THINGYthere's only 2 more after this one, I promise

Answers

Step-by-step explanation:

1. we can find the slope of the line using this formula:

\(\frac{y_2-y_1}{x_2-x_1}\)

y2, y1, x2, x1 are constants from the two coordinates given, so we just plug them into the formula

\(\frac{-13-19}{-1-3}\)

now we evaluate on both ends of the fraction

\(\frac{-32}{-4}\)

simplify

\(8\)

the slope is 8

2. we are given a graph which means we can simply count the slope

the slope means:

\(\frac{rise}{run}\)

which is the change in y over the change in x , this means that we can start at a coordinate and count the slope

using this method, we get a slope of 2

3. the slope is the change in y over the change in x. the y values are decreasing by -8 while the x values are increasing by ones

this means our slope is

\(\frac{-8}{1}=-8\)

4. we just have to use the aforementioned slope formula above

\(\frac{8-(-10)}{0-9}\)

evaluate

\(\frac{18}{-9}\)

simplify

\(-2\)

the slope is -2
