Answer:

\frac{1}{4}

Step-by-step explanation:

3 out of 12 children at the day care center are 5-year-olds. So, the probability of a randomly selected child being a five-year old is \frac{3}{12}, or \frac{1}{4}.

-4m + 2n = 6<br> -4m + n = 8<br> solve for and x and y steps

<u><em>I am doing this problem assuming that you mean to solve for m and n as x and y do not exist in this system of equations.</em></u>

<u><em /></u>

-4m+2n=6

-4m+n=8

We can see that the coefficient of x for both equations are -4; therefore, elimination with subtraction is possible.

<u>First equation - second equation</u>

n=-2

<u>Then substitude back in to solve for m</u>

-4m+(-2)=8

4m=10

m=5/2

Therefore the answer is

n= - 2

m= 5/2

I hope this helped and if you have any questions please ask.

Look at the graph shown below:
lina2011 [118]

Answer:

Well in order to find the equation you are looking for you first must find the slope of the line.  Since it gives you two points at (-4, 1) and at (0, 4), use these points to find the slope.  

y = (3/4)x + 4 is the answer

Step-by-step explanation:

Simplify this expression
I am Lyosha [343]
Hello there!

Let's put these into simpler terms:
-7s + 3s + 2s 
10 - 8 - 7

-7s + 3s = -4s
-4s + 2s = 2s

10 - 8 = 2
2 - 7 = -5

We are now left with:
2s - 5, which is your simplified expression.

I hope this helps!

There are 11 outcomes for the two events happening one after another. Since the spinner has five outcomes and the number cube has six outcomes, you add the two outcomes together and get 11.
