By matching the statistical measures with their corresponding values, we have:

Median: 23.5

Mean: 22.5

Mode: 20, 24, 25, 26

Lower Quartile: 21.5

Upper Quartile: 24.5

To match the statistical measures with their corresponding values, we need to analyze the dataset and identify the appropriate measures. Here's the breakdown:

Median: The median is the middle value of the dataset when it is arranged in ascending order. In this case, since we have 12 data points, the middle two values are 23 and 24. Therefore, the median is the average of these two values, which is 23.5.

Mean: The mean is calculated by summing up all the values in the dataset and dividing by the total number of values. Adding up the given values, we get 262. Dividing this sum by 12 (the number of values), we obtain a mean of 22.5.

Mode: The mode represents the value(s) that appear(s) most frequently in the dataset. In this case, the values 20, 24, 25, and 26 all appear twice, making them the modes of the dataset.

Lower Quartile: The lower quartile divides the dataset into four equal parts, with 25% of the data falling below it. To find the lower quartile, we need to locate the value that is greater than or equal to 25% of the data. In this case, the 25th percentile falls between the values 21 and 22. The lower quartile is the average of these two values, which is 21.5.

Upper Quartile: The upper quartile divides the dataset into four equal parts, with 75% of the data falling below it. Similar to the lower quartile, we need to locate the value that is greater than or equal to 75% of the data. In this case, the 75th percentile falls between the values 24 and 25. The upper quartile is the average of these two values, which is 24.5.

The probable question may be:

"Match the statistical measures (median, mean, mode, lower quartile, upper quartile) with their corresponding values for the dataset: 20, 20, 21, 22, 23, 23, 24, 24, 25, 25, 26, 26."

The tiles provided represent potential statistical measures and values, and the task is to match the correct measure with its corresponding value.

A rectangular community swimming pool is 31 2/3 meters long and 7 1/5 meters wide. The area around the swimming pool is covered with tiles. The area covered with tiles is 25% of the total area covered by the swimming pool. The total cost of the tiling is $712.50. What is the cost of the tiling per square meter?

Answers

Answer:

$12.50

Step-by-step explanation:

First, we find the area: 31 2/3 * 7 1/5 = 95/3 * 36/5 = 3,420/15 = 228 square meters. Then, we find the part that the tiles cover: 228 * 0.25 = 57 square meters. Now, we find the cost of the tiling per square meter by dividing the total cost by the total amount of tiling: $712.50 / 57 = $12.50. $12.50 will be your answer.

Answers

Answer:

Derions answer is not correct becuase 500 x 0.015=7.5 inches.  If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.  

If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.

Sam has 6x + 8 dollars saved. Teresa has saved 14x + 32 dollars. Together they have $220 saved. How much money have they each saved individually?

Answers

Sam has saved $62 and Teresa has saved $158

Step-by-step explanation:

given,

dollars saved by Sam = 6x + 8

dollars saved by Teresa = 14x + 32

total money = $220

a/q

money saved by,

sam + Teresa = $220

so,

6x + 8 + 14x + 32 = 220

20x + 40 = 220

20x = 220 - 40 = 180

x = 180/20 = 9

x = 9

now,

money saved by,

Sam = 6x + 8 = 6(9) + 8 = $62

Teresa = 14x + 32 = 14(9) + 32 = $158

therefore,

money individually saved by Sam is $62 and by Teresa $158.

Does the movement of air masses make weather prediction harder or better?
Here is some text 2 help u with the question:
The reason is they must take into account several large-scale phenomena. Each unique phenomena is governed by multiple variables and factors. For example, supercomputers must consider how the sun will heat the Earth's surface and how air pressure differences will form winds. They consider how water-changing phases (from ice to water or water to vapor) will affect the flow of energy. They even have to try to calculate the effects of the planet's rotation in space. This rotation moves the Earth's surface beneath the atmosphere. Small changes in any one variable in any one of these complex calculations can profoundly affect future weather.

What’s the answer and how do i find slope?

Answers

The answer would be m = -7

You can find the slope by putting the two ordered pairs into the formula: y2-y1/x2-x1.

y2 is the second y, being 8 in your case.

x2 is the second x. Being -2 in your case.

y1 is the first y, being -6 in your case.

x1 is the first x. Being 0 in your case.

After plugging in these numbers you will get 8- -6/-2-0. This will get you 14/-2. which will equal -7, the slope.


I can explain more if you want.

Hope this helped!! :)

Answer:

the answer should be -7

Step-by-step explanation:

you find slope by using the formula y2-y1/x2-x1

- Can a whole number be 5 more than another number and
also 5 times as many as the other number? Give an example
to explain your answer.

Answers

Answer:

Nope

Step-by-step explain

1+5=6

6/5 is not 1

2+5=7

7/5 is not 2

NO, a whole number can't be 5 more than another number, & 5 times another number.

Let a whole number be = n

5 more than whole number = n + 5 ; And 5 times the whole number = 5n

Equating them , n + 5 = 5n

5n - n = 5

4n = 5

n = 5 / 4

5 / 4 is not a whole number, as it is in fractional form.

Also, 5/4 + 5 = (5 + 20) / 4 = 25 / 4

5 / 4 x 5 = 25 / 4

Both above sum & product are also in fractional form, so are not whole numbers.

Hence proven.
