Equation at the end of step 1 : (8x + 2 • (x - 7)) - (10x - 14) = 0 Step 2 :Pulling out like terms :

2.1 Pull out 10x-14

After pulling out, we are left with :
 (10x-14) • ( 1 +( (-1) ))

Step 3 :Pulling out like terms :

3.1 Pull out like factors :

10x - 14 = 2 • (5x - 7)

Is the standard deviation of the sample a good estimate of the variation of salaries of tv personalities in general?

PolarNik [594]

The correct answer to this would be:

“No, because the sample is not representative of the whole population.”

Since the sample values are the 10 highest annual salaries of TV personalities, they give almost no information about the salaries of TV personalities as a whole or in general.

I do not understand this problem

Vesnalui [34]

Answer:

16c² + 32cd + 16d²

Step-by-step explanation:

A polynomial is an expression consisting of variables and coefficients. For example, $4x^3+3x^2+6x-4$ is an example of a cubic polynomial.

Area of a square = side length x side length

Therefore, given the side length of this square is 4c + 4d, then the area can be expressed as:

area = (4c + 4d) x (4c x 4d) = (4c + 4d)²

If we expand the brackets we get:

area = 16c² + 32cd + 16d²
