A data set has a mean of 7, a median of 5, and a mode of 8. Which of the numbers (7, 5, or 8) must be in the data set?


If possible, please explain in words, thank you. :)

Answers

Answer 1
5 must be in the data set: median means it’s the middle number in the set. so if the data was [2,3,5,6,7], 5 is the median.
Answer 2
8 has to be in the data set because 8 had to be there to be a mode were you can have 5 as the median if the set was like this 234678 because 4&6 both are in the middle so you have to do the middle of that which is 5 so that’s the median without having the number 5.

Answer:

  (47xy)/(6√3)

Step-by-step explanation:

A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.

A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.

A quotient is formed when a first value is divided by a second value.

Here is the quotient of our variable term and our constant:

The formula for finding the volume of a rectangular prism is V = Bh. A rectangular prism with dimensions _________ will have a volume of 150 cubic units.

Answers

Answer: 10 * 5 * 3

Step-by-step explanation:

We want to find a base and a height that will multiply together to equal 150 [tex]units^{3}[/tex].

One solution is a [tex]B = 50 units^{3}[/tex] and [tex]h = 3 units^{3}[/tex].

Thus we need a length and width of the base that will multiply together to equal 50 [tex]units^{2}[/tex]. One solution is 10 units * 5 units.

Putting this all together, we have a solution of 10 units * 5 units * 3 units, which will have volume of 150 cubic units.

Part C: Greg had a rectangular vegetable garden that was 4 feet wide by 5 feet long. He increased the length of his garden by 2 feet and doubled the width. How many square feet larger is the area of his new garden compared to the area of his old garden? In a short paragraph, explain your answer in your own words.

Answers

part a: c. 96 square feet

part b: 60 inches

part c: 36 square feet


explanation: I multiplied 4 and 5 because area = l•w meaning the garden was originally 20 square feet. I then doubled the making it 8 and added two feet to the length making it 7 feet. Since area equals l•w i multiplied 8 and 7 getting 56 square feet. Since the question asked, “how many square feet larger,” I subtracted the new area, 56 square feet, by the old one, 20 square feet, and got 36 square feet.

Answers

Answer:

Part A: 56

Part B: 43.9

Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean

Step-by-step explanation:

Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.

Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.

Part C: explanation in answer.

Hope this helps :)

for part a you can just go to an excel numbers in a column then click sum then click medien then select the column.
