Answer:
So the answer is -7
Step-by-step explanation:
2z + 8 = −6
2z + 8 -8 = -6 -8 ( add - 8 for both sides)
2z = -14
2z/2 = -14/2 (divide both sides by 2)
z = - 7
So the answer is -7
7x - 4x - x + 3
2x + 3

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:
