Answer:

The answer to your question is: letter A

Step-by-step explanation:

7 - 2z - 4(z³ - (z³ +4z² + 11z +14)/z + 2)

The result of the division was x² -2x + 7, then

7 - 2z - 4(z³ - z² + 2z - 7)

7 - 2z - 4z³ + 4z² - 8z + 28

-4z³ + 4z² - 10z + 35

Synthetic division

1 4 11 14 -2

-2 -4 -14

1 2 7 0

then = z² - 2z + 7

Which would best display the following data if you wanted to display the numbers which are outliers as well as the mean? [4, 1,

Serhud [2]

Arranging data in ascending order to identify the outlier and calculate the mean

Step-by-step explanation:

Given the data as: [4, 1, 3, 10, 18, 12, 9, 4, 15, 16, 32]

Arrange in ascending order

[1, 3, 4, 4, 9, 10, 12, 15, 16, 18, 32 ]

The outlier is 32

Finding the mean;

Mean=sum of data set/number of data set

Sum= 1 + 3+ 4+ 4+ 9+ 10+ 12+ 15+ 16+ 18+ 32=124

Number of data set=11

Mean=124/11=11.27
