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

Answer: Range and mean

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
If George's highest mark is recorded higher than it actually was, then only the maximum test score and range will be altered.

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 interquartile range (IQR) is the best choice here to describe the variability of the data set with a single number.

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
The value that can be used to describe how the values in the data set vary with a single number is the Mean Absolute Deviation (MAD), which is given as 3.5 in the table.

Answer:
D. Mean Absolute Deviation

4) Necolai reported his weekly earning for the first four weeks as $87, $105, and $125.

A) How much does he have to earn in the fifth week to achieve an average of $130 per
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
taxes? How much of his total pay does he have left after taxes? Show and explain all
of your work.


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.

Question A:
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.

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.

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.

726 I believe

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.

Name 3 ways Mansa Musa impacted Africa and or African culture. Mansa Musa (Musa I of Mali) was the ruler of the kingdom of Mali from 1312 C.E. to 1337 C.E. During his reign, Mali was one of the richest kingdoms of Africa, and Mansa Musa was among the richest individuals in the world. The ancient kingdom of Mali spread across parts of modern-day Mali, Senegal, the Gambia, Guinea, Niger, Nigeria, Chad, Mauritania, and Burkina Faso. Mansa Musa developed cities like Timbuktu and Gao into important cultural centers. He also brought architects from the Middle East and across Africa to design new buildings for his cities. Mansa Musa turned the kingdom of Mali into a sophisticated center of learning in the Islamic world.Mansa Musa came to power in 1312 C.E., after the previous king, Abu Bakr II, disappeared at sea. Mansa Abu Bakr II had departed on a large fleet of ships to explore the Atlantic Ocean, and never returned. Mansa Musa inherited a kingdom that was already wealthy, but his work in expanding trade made Mali the wealthiest kingdom in Africa. His riches came from mining significant salt and gold deposits in the Mali kingdom. Elephant ivory was another major source of wealth.When Mansa Musa went on a pilgrimage (hajj) to Mecca in 1324 C.E., his journey through Egypt caused quite a stir. The kingdom of Mali was relatively unknown outside of West Africa until this event. Arab writers from the time said that he travelled with an entourage of tens of thousands of people and dozens of camels, each carrying 136 kilograms (300 pounds) of gold. While in Cairo, Mansa Musa met with the Sultan of Egypt, and his caravan spent and gave away so much gold that the overall value of gold decreased in Egypt for the next 12 years. Stories of his fabulous wealth even reached Europe. The Catalan Atlas, created in 1375 C.E. by Spanish cartographers, shows West Africa dominated by a depiction of Mansa Musa sitting on a throne, holding a nugget of gold in one hand and a golden staff in the other. After the publication of this atlas, Mansa Musa became cemented in the global imagination as a figure of stupendous wealth.After his return from Mecca, Mansa Musa began to revitalize cities in his kingdom. He built mosques and large public buildings in cities like Gao and, most famously, Timbuktu. Timbuktu became a major Islamic university center during the 14th century due to Mansa Musas developments. Mansa Musa brought architects and scholars from across the Islamic world into his kingdom, and the reputation of the Mali kingdom grew. The kingdom of Mali reached its greatest extent around the same time, a bustling, wealthy kingdom thanks to Mansa Musas expansion and administration.Mansa Musa died in 1337 and was succeeded by his sons. His skillful administration left his empire well-off at the time of his death, but eventually, the empire fell apart. Well after his death, Mansa Musa remained engrained in the imagination of the world as a symbol of fabulous wealth. However, his riches are only one part of his legacy, and he is also remembered for his Islamic faith, promotion of scholarship, and patronage of culture in Mali.
