Using <em>statistical concepts</em>, it is found that the standard deviation of the probability distribution is of
When a constant is multiplied to each data in a variable, both the <u>mean and the standard deviation</u> are multiplied by the constant.
In this problem, the standard deviation, which is the square root of the variance, is of:
The price of each is of $1.5, hence:

a to C would be 4 3/4 + 2/3
3/4 + 2/3 = 9/12 + 8/12 = 17/12 = 1 5/12
1 5/12 + 4 = 5 5/12 total distance
Answer:
False
Step-by-step explanation:
Substitute x and y with the numbers in the coordinate pair.
Just as a recap-
3 is the x value
7 is the y value
2(3) + 2(7) = 20
20 < 20
This is not true since 20 = 20
Hence, the answer is false
Answer:
Step 4
Step-by-step explanation:
Tasha was correct in all the steps leading up to the fourth one. However, in the fourth step was where she messed up.
She said that: 
However, when we have a negative exponent, in order to get rid of the negative, we simply take the reciprocal of the number and then make the exponent positive. Here, the answer should be:
