The height of the average wave, in feet, over thours at Sandy Beach is modeled by the equation below.
2 answers:
Answer:
Check below
Step-by-step explanation:
With the information given, let's consider some aspects of Sandy Beach behavior.
1. Sandy Beach
Let's calculate the period of this function
The Period of sin function is
2. Verifying the Range, in this case the lapse of time.
A <em>sin</em> function varies from -1 to 1, i.e.
So, within an interval form 1 to 9 hours the waves at Sandy Beach come and go.
3. Check the graph below.

Step-by-step explanation:
:proportion of male smoker lung deaths is same for the four given tar level categories.
:proportion of male smoker lung deaths is not the same for the four given tar level categories.
Expected frequency=1177/4=294.25
Tar level Observed Freq.(O) Expected Freq.(E) (O-E)^2/E
0-7 107 294.25 120.435
8-14 375 294.25 5.643
15-21 553 294.25 227.533
>=22 183 294.25 42.061
Total= 1177 1177 395.673
Total chi square score=395.673
df=4-1=3
p-value=CHIDIST(395.673,3)<0.001
p-value<0.001,Reject null hypothesis.
There is sufficient evidence that the proportion of male smoker lung deaths is not the same for the four given tar level categories.
Using the slope concept, it is found that the base of the left field wall is 361 feet from a point on level ground directly below the top row.
<h3>What is a slope?</h3>- The slope is given by the <u>vertical change divided by the horizontal change.</u>
- It's also the tangent of the angle of depression.
In this problem:
- The vertical change is of 90 ft.
- The horizontal change is of x.
- The angle of depression is of 14º.
Hence:
Hence, the base of the left field wall is 361 feet from a point on level ground directly below the top row.
