What two different pairs of decimals whose sums are 8.69?

To solve this problem, you add all the numbers together and divide by the total amount of things. In this case, there are six scores, 210, 195, 213, 201, 226, and 155. You would add all of these things together, and then divide by six. All of these things added together equals 1,200. This divided by 6 is 200. David's average score would be a. 200. Hope this helps!

The value of b that makes x-2 a factor of x² - bx + b is 4.

Polynomial is an expression involving the operations of addition, subtraction, multiplication of variables.

Types of polynomials are quadratic, linear, cubic and so on.

The factor theorem states that; when f(k) = 0, then (x – k) is a factor of f(x).

Given that x-2 is a factor of x² - bx + b, hence:

f(2) = 2² - b(2) + b = 0

4 - 2b + b = 0

b = 4

Therefore the value of b that makes x-2 a factor of x² - bx + b is 4.

we have that

we know that

If is a factor of

then

for

is equal to zero

so

therefore

the answer is

the value of b is equal to

Answer:

-3=b

Step-by-step explanation:

since its a -4 u seperate it from the vari by dividing 12 by the -4 ( since -4b inplies multiplcation. u always do inverse operation.)

Answer:

= 3.0

Step-by-step explanation:

represents the median of the data set.

From the box plot the median is the horizontal line inside the box and is positioned at 3.0
