week? Show and explain all of your work.
B) After five weeks of his earning, he has to pay 28% in taxes. How much were the

ANSWER BOTH QUESTIONS QUESTION A AND QUESTION B.
Answers
Answer: A) $333
B) $468
Step-by-step explanation:
A) First we multiply. 130x5=650 Now we know that we have to get $650 total in 5 weeks in order to get an average of $130 per week.
87+105+125=317
650-317=333
Necolai has to earn $333 the fifth week to achieve an average of $130 per week.
B) 28% of 650 = 182
Now subtract the taxes from his earnings. 650-182=468
Necolai has $468 of his total pay after taxes.
To find how much Necolai has to earn in the fifth week to achieve an average of $130 per week, we have to use the concept of mean.
The average of five weeks' earnings should be $130. Therefore, the sum of his five-week earnings should be:
5 * 130 = 650
Necolai's total earnings for the first four weeks are:
87 + 105 + 125 + x (earning in the fifth week) = 317 + x
317 + x + y = 650
where y represents his earnings in the fifth week. Solving for y, we get:
y = 650 - 317 - x
y = 333 - x
So, Necolai has to earn $333 in the fifth week to achieve an average of $130 per week.
Question B:
After earning $87, $105, $125, and x dollars (from the third week), Necolai’s total earning are $317 + x. After 5 weeks, Necolai has to pay 28% in taxes, which means he gets to keep 72% of his earnings.
The taxes are calculated as:
Taxes = 0.28 * (317 + x)
Taxes = 88.76 + 0.28x
Therefore, the taxes he has to pay after five weeks are $88.76 + 0.28x.
The portion of his total earnings that he keeps after taxes is:
Total earnings - Taxes = (317 + x) - (88.76 + 0.28x)
Total earnings - Taxes = 228.24 + 0.72x
Therefore, after paying taxes, Necolai is left with $228.24 + 0.72x of his total earnings.

George wrote seven tests and each was marked out of 100. No two of his marks were the same. He recorded the seven marks to do a statistical analysis. He accidentally recorded his highest mark higher than it actually was. How many of the following are altered because of his mistake? 1. Mean 2. Median 3. Minimum test score 4. Range
Answers
Explanation: median isn't affected because it is the middle value of all the values. If the highest score is already at the end of the list, then it won't go up or down if the score is even higher. Minimum isnt affected because that is the lowest score, which has seemingly been entered correctly. Mean is affected because it is the average. If one score is higher than it should be, it will raise the average. Range isnaffected because it is the number in between the max and min (max-min). If the max is higher, then the range increases
Mean: Calculated by adding all the test scores together and then dividing by the total number of tests, so the error in the highest score does not affect the mean.
Median: Calculated by finding the middle value in a set of data, so the error in the highest score does not affect the median, as it will still be the fourth highest test score.
Minimum: The lowest test score remains the same, as it will not be affected by the error in the highest score.
Range: Calculated by subtracting the lowest test score from the highest score, so if the highest score is incorrect, the range will also be incorrect.
Therefore, only the maximum score and the range are altered by George's mistake, and the mean, median, and minimum score remain the same.

The values in the table describe a data set.
Minimum 20
Mean 30
Mean Absolute Deviation 3.5
Median 35
Interquartile Range 10
Maximum 55
Which value can be used to describe how the values in the data set vary with a single number?
A. median
B. maximum
C. interquartile range
D. mean
Answers
The IQR is 10, indicating the middle 50% of the data values lie within the range of 28 to 43 (35 +/- 10 is 28-43).
The other choices are:
Mean (30) - Describes the central tendency but not variability.
Median (35) - Also describes central tendency but IQR gives a better sense of spread.
Maximum (55) - Only describes the upper limit, not variability.
So the interquartile range (IQR) of 10 is the best choice to capture how spread out or varied the values in the data set are.
The answer is C. interquartile range
Answer:
D. Mean Absolute Deviation

A photographer’s darkroom needs a new coat of black paint on all surfaces of the room, including the ceiling and the floor. The room is a cube with edge length 11
feet. How much surface area must be painted?
Answers
The surface area of a cube is given by the formula 6s^2, where s is the length of the edge. In this case, s = 11 feet, so the surface area of the cube is:
6s^2 = 6(11)^2 = 6(121) = 726 square feet
Since the room has six surfaces that need to be painted (four walls, one ceiling, and one floor), the total surface area that needs to be painted is:
6 x 726 = 4356 square feet
Therefore, the photographer's darkroom needs to have 4356 square feet of black paint applied to all of its surfaces.

Kylie brought 5 pears to soccer practice to share with her teammates. She cuts each pear into thirds. How many slices of pears does she have to share with her teammates? Which equations can you use to solve the problem? Select two equations.
A. 5 × 3 = 15
B. 1/5 × 1/3 = 1/15
C. 1/5 × 3 = 3/5
D. 5 ÷ 1/3 = 15
E. 1/3 ÷ 5 = 1/15
Answers
Answer:
A and D
Step-by-step explanation:
One pear is split into thirds. That means that one pear can become 3 slices. Because you have 5 pears, you have 15 slices. By multiplying 3 (slices) and 5 (pears), we receive the answer of 15 slices.
The answer is A and D.
Step-by-step explanation - Kylie brought 5 pears to practice. Because she cut each of them into thirds, this means that each pear equals 3 slices - therefore making the equation 5 x 3 = 15 and also making the equation 5 ÷ 1/3 because them two both equal 15.

The following system of linear equations is shown in the graph.

x − 4y = 4
a coordinate plane with two lines that pass through the points 0 comma negative 1 and 4 comma 0
How many solutions does the system of linear equations have?
No solution
Infinitely many solutions
One solution at (4, 0)
One solution at (0, −1)
Answers
The system of linear equations is given as:
y = 1/4x - 1
x - 4y = 4
To find the solution, we can substitute y in the second equation with 1/4x - 1:
x - 4(1/4x - 1) = 4
x - x + 4 = 4
4 = 4
The equation 4 = 4 is always true, which means that the system of linear equations has infinitely many solutions.
Therefore, the answer is:
Infinitely many solutions.
