WILL MARK BRAINLIST!! Olivia rolls two fair number cubes numbered from 1 to 6. She first defines the sample space as shown below
ArbitrLikvidat [17]

The probability of getting a total of 10 will be \frac{1}{12}

<em><u>Explanation</u></em>

The total possible sample spaces for rolling two fair numbered cubes are :

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6) (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6) (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6) (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6) (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6) (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)

There are total 36 sample spaces.

We need to get a sum of 10 , so the possible sample spaces will be:

(4, 6) , (5, 5) and (6, 4)

That means there are 3 possible sample spaces for getting a sum of 10.

So, the probability of getting a total of 10 = \frac{3}{36} = \frac{1}{12}

Give your answer in its simplest form.

Answer:

Is the question to develop the equation for the straight line shown?

If so,<u> y = (3/4)x + b</u>

Step-by-step explanation:

Look for an equation with the form y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).

Calculate Slope using the Rise/Run.

Pick any two points.  I chose (-4,0) and (4,6).

Going from left to right:

Rise = (6 - 0) = 6

Run = (4 - (-4)) = 8

Slope is Rise/Run, 6/8 or 3/4

So we have:  y = (3/4)x + b

We can see that the y-intercept, b, is 3 (the value of y when x = 0).

The full equation becomes :<u>  y = (3/4)x + 3 </u>

igomit [66]

Answer: 170

Step-by-step explanation:

We can set up simultaneous equations such that:

E = R+400

E - 60 = 3R

Solving gives R = 170 and E =570
