Answer:
Step-by-step explanation:
4
EF and FG are equal so EF would be 6.1
6.1+6.1=12.2
EG=12.2
Answer:
x=16
Step-by-step explanation:
2(x/8)=2
2x / 16=2
x 16 x 16
2x=32
2x/2= 32/2
x= 16
Answer:
25.12 meters
Step-by-step explanation:
The circumference of a circle is given by
(1)
where:

r is the radius of the circle
In this problem, the parachute has a diameter of 8 meters:
d = 8 m
The radius of a circle is equal to half of its diameter, so the radius of the parachute is:

And therefore, by applying eq.(1) we can find the circumference of the circle:

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
