What is the value of the expression? Show all work.<br> -9 - 6 + 8 ÷ -4 * -2?
nadya68 [22]

Step-by-step explanation:

To do Order of Operations, we need to go with the order of the formula, PEMDAS.

P= Parenthesis

E= Exponents

M= Multiply (Whatever Comes First in Equation: M and D)

D= Divide

A= Addition (Whatever Comes First in Equation: A and S)

S= Subtraction

---------------------------------------------

So, we need to start with parenthesis, there aren't any, so we move on to Exponents.

There are no Exponents either, so we start with division, then multiplication.

(We always have to go left to right).

So,

-9 - 6 + <u>8 / -4</u> x -2

-9 - 6 + <u>-2 x -2</u>

-9 - 6 + 4

Our problem is:

-9 - 6 + 4

We do subtraction, then addition. (Left to Right)

<u>-9 - 6 </u>+ 4

<u>-15 + 4</u>

-11.

Therefore, the answer is -11.

You roll a number cube twice what is the probability of rolling a 2
Colt1911 [192]

The probability of getting a 5 from the first rolling is 1/6.  The probability of getting an even number  is 1/2 (= 1/6 (for a 2) + 1/6 (for a 4) + 1/6 (for a 6)).  As the two rollings are independent, you can just multiply two probability values to come up with a final answer.  That is, (1/6)·(1/2) = 1/12.

Note that I did not write this. This answer comes from Wyzant. I am only linking this to you so that you'll get the answer quickly.
