11. Find the mean and median of the following data:
2, 5, 7, 1, 9, 13, 10, 8, 7

Step-by-step explanation:

Mean: To find the mean add all the numbers together and divide the numbers by the number of numbers listed. Remember Round when Necessary!

1.) Add the numbers together! 2+5+7+1+9+13+10+8+7= 62

2.) DIvide 62 with the amount of numbers listed which is 9

Equation: 62/9

3.) The answer is 6.88888888889, but you would need to round to the nearest hundredth or tenth.

If rounded to nearest Hundredth: 6.89

Nearest Tenth: 6.9

Median: To find the median you would need to order the numbers smallest to greatest then find the middle number! Key concept: If there is an odd amount of numbers there should be a middle number! But if there is an even amount of numbers find the 2 middle numbers, add them together and divide by 2.

1.) Order the numbers LEAST TO GREATEST!

The order: 1,2,5,7,7,8,9,10,13

2.) Identify middle number *numbers if even amount!* (in this case there are 9 numbers for which you would need to identify one number!)

1,2,5,7,7,8,9,10,13 (Number in Bold should be the Median)

3.) Answer! 7 is the Median!

Therefore, The Mean of the data is 6.89 (rounded to the nearest hundredth) The Median is 7!

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
