(f-g)(x)=2x+1-(x^2-7)
(f-g)(x)=2x+1-x^2+7
(f-g)(x)= -x^2+2x+8
Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth. 12,7,12,9,2,15,6,6,6,1,11
Galina-37 [17]
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

This problem requires PEMDAS
Parentheses ( )
Exponents ^
Multiplication
Division
Add
Subtract
Start by solving anything in parentheses. There's an exponent within the parentheses, so we change that 2^2 into 4 and also make sure to multiply 5 x 2 before subtracting.
-4 - (2 + -24 - 4 - (4-10))
-4 - (2 + -24 - 4 - (-6))
Again, solve parentheses first.
-4 - (-22 - 4 - (-6))
-4 - (-26 + 6)
-4 - (-20)
-4 + 20
Answer is 16
