Answer:
I agree that this question can be confusing:
Apparently point A and point B must be on the same straight line (measured from the light house or the question would be nonsensical)
tan 13 = H / DA where H is height of lighthouse
tan 8 = H / DB tangent measured from point B
tan 13 / tan 8 = DB / DA
DB = .2309 / .1405 * 1279 = 2101 ft
DB - DA = 2101 - 1279 = 822.0 ft
The percentage of the people surveyed that were satisfied with the car is 45%.
<u>Given the following data:</u>
- Total population = 1,600 people
- Number of car owner = 720 people.
To determine the percentage of the people surveyed that were satisfied with the car:
<h3>
How to solve for a percentage.</h3>
In this exercise, you're required to calculate the percentage of the total population in this survey that would by a particular type of car again because they were satisfied with it. Thus, we would solve for the percentage as follows;
![Percent = \frac{Satisfied\;persons}{Total\; population} \times 100](https://tex.z-dn.net/?f=Percent%20%3D%20%5Cfrac%7BSatisfied%5C%3Bpersons%7D%7BTotal%5C%3B%20population%7D%20%5Ctimes%20100)
Substituting the given parameters into the formula, we have;
![Percent = \frac{720}{1600} \times 100\\\\Percent = 0.45 \times 100](https://tex.z-dn.net/?f=Percent%20%3D%20%5Cfrac%7B720%7D%7B1600%7D%20%5Ctimes%20100%5C%5C%5C%5CPercent%20%3D%200.45%20%5Ctimes%20100)
Percent = 45%

Hi,yes, they do.
(2/2)/(4/2)=1/2
or
1*2/2*4=2/4
Hope this helps you.

Answer: The z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
Step-by-step explanation:
Given: Average monthly electric bill in Illinois = $83
Average monthly electric bill in Florida = $102
Formula of z :
In Illinois, the mean monthly electric bill is $85, with a standard deviation of $3.20.
![z=\dfrac{83-85}{3.20}= -0.625](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B83-85%7D%7B3.20%7D%3D%20-0.625)
In Florida, the mean monthly electric bill is $105, with a standard deviation of $4.00.
![z=\dfrac{105-102}{4}=\dfrac{3}{4}=0.75](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B105-102%7D%7B4%7D%3D%5Cdfrac%7B3%7D%7B4%7D%3D0.75)
Hence, the z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
