Hello,

Why "Multiply the polynomial by distribution"  ?

It's s t u p i d, you compliquate the equation.

In order to find the roots of P(a)=(a-3)(a²+2a-6)=0

a²+2a-6

=(a²+2a+1)-7

=(a+1)²-7

=(a-√7)(a+√7)

P(a)=(a-3)(a-√7)(a+√7)

Roots are 3,√7 and -√7

(If i have well understood the question , sorry if not)

When the outliers are removed, how does the mean change?
vagabundo [1.1K]

Answer:

The mean increases by 3.

Step-by-step explanation:

<u>What's an outlier?</u>

  • An outlier is a data point that's very different from the other data points. In this example, the outlier is 50, as the other data points are around the number 80.

<u>What's the mean of a data set?</u>

  • The mean is the average of a data set. It's found by adding up all the numbers in the set and then dividing by the number of data points there is.

<u>How do we solve this problem?</u>

First, we find the mean of the data set with the outlier, 50.

  • \frac{50+76+78+79+79+80+81+82+82+83}{10}
  • \frac{770}{10}
  • 77  

Next, we find the mean of the set without the outlier.

  • \frac{76+78+79+79+80+81+82+82+83}{9}
  • \frac{720}{9}
  • 80

Lastly, we subtract 77 from 80 to find the difference.

  • 80 - 77 = 3

Therefore, the answer is The mean increases by 3.
