A normal distribution is bell-shaped and symmetric about its mean.

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:

Answer:
(0.1,1.1)
Step-by-step explanation:
we have
Solve the system of equations by graphing
The solution is the intersection point both graphs
The solution is the point (0.081,1.093)
see the attached figure
Round to the nearest tenth ----> (0.1,1.1)
Please find the attached diagram for a better understanding of the question.
As we can see from the diagram,
RQ = 21 feet = height of the hill
PQ = 57 feet = Distance between you and the base of the hill
SR= h=height of the statue
=Angle subtended by the statue to where you are standing.
= which is unknown.
Let us begin solving now. The first step is to find the angle which can be found by using the following trigonometric ratio in
:
Which gives to be:
Now, we know that and
can be added to give us the complete angle
in the right triangle
.
We can again use the tan trigonometric ratio in to solve for the height of the statue, h.
This can be done as:
Thus, the height of the statue is approximately, 8.45 feet.
