When the population mean and standard deviation are known, you use the standard normal distribution
<h3>How to determine the distribution?</h3>
There are several probability distributions; these include
- Normal distribution
- Poisson distribution
- Chi square distribution
- Binomial distribution
- Etc
Of all these distribution, only the standard normal distribution can be used when the population mean and standard deviation are known,
Note that it is also referred to as the z-distribution

the answer is C. because it is the only one that does not contain a common factor :)
Answer:

Step-by-step explanation:
.
m is the slope of the line. To find it we can do
which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So:
. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant
.

- Re-arranging to get b
Now re-write the equation as we have the constants.

Answer:
5760
Step-by-step explanation:
7200-20%=5760
Answer:
$0.3
Step-by-step explanation:
8.90x2=17.8
1.75x2=3.5
17.8+3.5=21.3
21.90-21.3=0.6
0.6/2=0.3
