Answer:
True
Step-by-step explanation:
A normal distribution shows a dense center , which would be the mean. Given a population or sample, the bulk of the data would be found near the mean and and spreads out thinner towards the ends when the data is said to be normally distributed. When graphed you will see that the data form a bell-shaped curve.
Attached below is an example of how it would look:

AB^2 + BC^2 = AC^2
AB^2 + 6^2 = square root 117^2
AB^2 + 36 = 117
Now subtract 117 from both sides
AB^2 = 81
AB = square root 81 = 9
Therefore AB is 9 cms.
AB^2 + 6^2 = square root 117^2
AB^2 + 36 = 117
Now subtract 117 from both sides
AB^2 = 81
AB = square root 81 = 9
Therefore AB is 9 cms.
