Range, mode, MAD, median IQR, mean

range=8, mode=1  Median=3 mean=4

Step-by-step explanation:

range= subtract largest from smallest

mode= most frequent

median= middle in an ordered data set

Mean= add them all up and divide by how many you addded up

Range : 8

Mode : 1

MAD : N/A

Median : 3

IQR : N/A

Mean : 4

Step-by-step explanation:

Finding Range:

To find range within a set of numbers, you have to find the smallest number, which in this case is 1. And the biggest number, being 9. Then subtract the biggest number by the smallest.

9 - 1

8 is our range.

Finding Mode:

Finding Mode is finding the most common (or repeated) number within the set.

1 , 1 , 3 , 6 , 9

One appears two times unlike all the other numbers appearing once, therefore having 1 as our mode.

Finding MAD :

I have never heard of this term so I wouldn't want to cheat or give you a wrong answer.

Finding Median :

Median is simply finding the number in the middle of the number set.

1 , 1 , 3 , 6 , 9

3 is in the middle of the set, making 3 our median.

Finding IQR :

Like MAD, I have never heard of this term so I wouldn't want to cheat or give you a wrong answer.

Finding Mean :

Mean is adding all the numbers together, then dividing that final value by the amount of numbers there are.

1 + 1 + 3 + 6 + 9

20

There are five numbers within the set.

20 / 5

4

4 is our mean.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70
