Answer:

the answer is 6

Step-by-step explanation:

you take the absolute value for both of them which is 2 and 8 but you keep the negative still so it would be -2+8 which is 6

Answer:

Step-by-step explanation:

The absolute value of -2 is 2, but with the negative on the outside it would be -2.

Next the absolute value of -8 is 8.

Therefore 8+-2=6

Answer:

9(x +y)

Step-by-step explanation:

You observe that both terms have a coefficient of 9. The distributive property lets you factor that out, so you can rewrite the expression as ...

9x +9y = 9(x +y)

_____

It might help to think of parentheses as a "bag." The expression 9(x+y) tells you the contents of one bag is (x+y) and you have 9 of them. You could think of x, and y as representing two different physical objects, for example, perhaps a ball and a cube.

The first expression, 9x +9y, tells you that you have 9 of each of these objects. The distributive property says this could be the result of dumping the contents of 9 bags, each containing one each of the objects. The expression 9(x+y) is the version of the expression that shows these objects as being grouped into 9 bags.

Answer:

(a) The value of a is 53.35.

(b) The value of a is 38.17.

(d) The value of a is 25.63.

(e) The value of a is 12.06.

Step-by-step explanation:

The probability density function of X is:

$f_{X}(x)=\frac{1}{55-22}=\frac{1}{33}$
