Answer:
Mean: 7.9
Median: 7
Mode: 6
Step-by-step explanation:
Sort the date set!
1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Then start by finding the mean of the data set!
Mean: the sum of all numbers divided by the amount of numbers
Mean = 1 + 2 + 6 + 6 + 6 + 7 + 9 + 11 + 12 + 12 + 15 = 87 divided by 11 = 7.9
Median: middle number in the data set
Data set: 1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Median = 7 because it is in the middle
Mode: the number that is being used the most
Data set: 1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Mode = 6 because it is used 3 times
A+ 2/2= -1
⇒ A+ 1= -1
⇒ A= -1 -1
⇒ A= -2
Final answer: A= -2~
