Answer: The central limit theorem tells us that when random samples are chosen the results tend to approach a normal distribution.
The basic idea is that the more random samples that you select, the closer you should get to the mean. In most cases, 30 or more samples is regarded as a large enough sample to get close to the mean. Our sample is 48, so we should be close to the mean.
Answer:
Sin(E) = 
Step-by-step explanation:
The full question is as follows :
To find - In the accompanying diagram, what is sin E?
Proof -
We know that,
Sin(theta) = (opposite side) / (hypotenuse)
From the diagram, we can see that,
Base = 3
Perpendicular = 5
Hypotenuse = 5
So,
For angle E,
Opposite side = 4
Hypotenuse = 4
∴ we get
Sin(E) =
Answer:
62°
Step-by-step explanation:
If it is a right triangle, subtract 90, from 180 and then subtract 28 to get D. D should = 62°
