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

Answer: add 1 to both sides
-1+r+1≥4+1
simplify
x≥5
Step-by-step explanation:
Answer: 9,000
Step-by-step explanation: there are 9 number options for the first digit and 10 for the other 3, so 9x10x10x10=9000
They both have the same absolute value. Their absolute value would be 3
Answer:
-1 1/3 as a mixed number (if they ask for it in simplest form, choose this one)
-4/3 as an improper fraction
Step-by-step explanation:
1. Keep, change, flip
4/5 x -5/3
2. Cross cancel the fives
4/1 x -1/3
3. Simplify
-4/3 or -1 1/3 (they're equivalent)
