Answer:

Step-by-step explanation:
Let
, that is a be any real number.
The inverse property of addition says that, the sum of a number
and its additive inverse
gives the identity element of addition which is zero.
That is :

We can rewrite this as 
From the above options, we have the correct answer to be the first choice
Answer:
Option B) In control as this one data point is not more than three standard deviations from the mean
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 104 rotations per minute
Standard Deviation, σ = 8.2 rotations per
We are given that the distribution of process is a bell shaped distribution that is a normal distribution.
Formula:

For x = 118

Thus, we could say that this data point lies within three standard deviations from the mean as:

Thus, it could be said
Option B) In control as this one data point is not more than three standard deviations from the mean
Answer:
4 hours
Step-by-step explanation:

21 · y = 3 · 28
21y = 84
21y ÷ 21 = 84 ÷ 21
y = 4
If you meant to say k=(-3)
First thing you would do is plug in the (-3) to a
Your equations would look like this:
k(a) = 4(-3) + 2
You would multiply 4 × -3, giving you -12.
k(a) = 12 + 2
Then you would add 12 + 2, giving you 14.
k(a) = 14
k(a) would equal 14.
