Answer:
1/12
Step-by-step explanation:
There are 36 possible outcomes
Out of the 36 there are only 3 where the sum is 4 that is (1,3),(2,2),(3,1)
Hence probability= 3/36 which equals to 1/12
Answer: B. x ^ 2/12 * y ^9/12
Step-by-step explanation:
Just got it correct on Edge.
s = 6 + e
s + e = 28
We can use this system of equations to find the exact values of s and e.
We have a current value of s, so we can find the exact value of e now.
e + e + 6 = 28
<em><u>Combine like terms.</u></em>
2e + 6 = 28
<em><u>Subtract both sides by 6.</u></em>
2e = 22
<em><u>Divide both sides by 2.</u></em>
e = 11
Now we have an exact value of e, and can solve for the value of s.
s = 6 + 11
s = 17

Mean Absolute Deviation is a quantity of measurement that gives you an idea how far, on average, are the data points deviating from the mean. Its equation is
MAD = ∑|x - μ| / N, where
x is a single data point
μ is the mean of the data set
N is the total number of data points
Suppose, a data set consist of the following: 4, 7, 5, 9, 6, 7, 7, 4. Let's solve first for the mean:
μ = (4+7+5+9+6+7+7+4)/8 = 6.125
Then, the MAD is equal to:
MAD = (|4 - 6.125| + |7 - 6.125| +|5 - 6.125| +|9 - 6.125| +|6 - 6.125| +|7 - 6.125| +|7 - 6.125| +|4 - 6.125|) ÷ 8
MAD = 11/8
MAD = 1.375
