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

Hope this helps ;)
Answer:
Y = (16 - 3x)/5
Step-by-step explanation:
3x + 5y = 16
subtract 3x from both sides:
16-3x = 5y
divide both sides by 5:
(16 - 3x) / 5 = y

The interior angles of a quadrilateral( 4 sided figure) add up to 360 degrees.
114 + 84 + 94 + x = 360
292 + x = 360
x = 360 - 292
x = 68 <== ur missing angle
