Answer:

Step-by-step explanation:

First let's calculate the probability of the sum of the cubes being 4, so we can subtract it from 100% to get the probability of the sum not being 4.

In order to be 4 we have the following outcomes.

Outcomes = {(1, 3), (2, 2)}, there are 2 outcomes out of 36 when the sum is equal to 4.

P(Sn4) = 100 \% - \frac{2}{36} \cdot 100 \% = 100 \% - \frac{100 \%}{18} = 100 \% (1 - \frac{1}{18}) = 100 \% \cdot \frac{17}{18} \approx  94 \%

Now to find the probability of the sum being greater than 5, we'll find the probability of it being less than or equal to 5.

Outcomes = {(1, 1), (1, 2), (1, 3), (1, 4), (2, 2), (2, 3)}, there are 6 outcomes out of 36.

Now to find the probability of the sum of the dice being greater than 5, we'll subtract the probability of the sum being less than or equal to 5 from 100%.

P(Bgt5) = 100 \% - [\frac{6}{36} \cdot 100 \%] = 100 \% (1 - \frac{1}{6}) = 100 \% \cdot \frac{5}{6} \approx 83 \%

The slope of the line whose equation is x-3y= 1 is<br> 0-3<br> -1/3<br> 0<br> 0<br> 1/3
insens350 [35]

x-3y= 1

The equation needs to be rewritten in proper Slope intercept form ( y = mx+b) where m is the slope and b is the y-intercept.

x-3y = 1

Subtract x from each side:

-3y = 1-x

Divide both sides by -3:

y = 1/-3 - x/-3

Simplify:

y = 1/3x - 1/3

The slope is 1/3

Is x = -7, the solution to -11 + 2x = -26? Justify your answer in complete sentences.
Natali5045456 [20]
First of all, you can move the +2x to the other side:
-11 = -26 - 2x

Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
 15 = -2x

Then you can divide both sides by 2:
7.5 = -x

Then you can flip the sides and the signs around:
x = -7.5

No, The answer is not -7, it is -7.5
Hope this helps! :)
