(x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15 as there is no remaider.
<h3>What is a factor of a polynomial?</h3>
We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given a polynomial function f(x) = x³ - x² - 17x -15.
If (x - 5) is it's factor then f(5) = 0.
∴ f(x) = x³ - x² - 17x -15.
f(5) = 5³ - 5² - 17(5) - 15.
f(5) = 125 - 25 - 85 - 15.
f(5) = 0.
So, the remainder is zero hence (x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15.

Answer:
A) 0.2
Step-by-step explanation:
From least to greatest, the data points are
6, 6, 6, 7, 7, 7, 8, 8, 8, 9
To find the mean, we find the sum of the data points and divide by the number of data points, 10. The sum of the data points is
6+6+6+7+7+7+8+8+8+9 = 72
Dividing by 10, the mean is 72/10 = 7.2.
The median is the middle number in the set. This is 7.
The difference between the mean and the median is
7.2-7 = 0.2.
