If a random sample of 20 persons weighed 3,460, the sample mean x-bar would be 3460/20 = 173 pounds.
The z-score for 173 pounds is given by:
Referring to a standard normal distribution table, and using z = 0.66, we find:
Therefore
The answer is: 0.2546
Converting angle measure of 55.45 to DMS notation we get 55 degrees 27 minutes 0 seconds
Step-by-step explanation:
We need to convert angle measure of 55.45 to DMS notation
DMS notation is Degree Minute and seconds
Solving:
We have 55.45, the value before decimal is considered as degrees and values after decimal can be minutes and seconds.
We can write it as 55 and 0.45
So, we have 55 degrees
To find minutes we will multiply 0.45 by 60
0.45*60 = 27 minutes
Since we have no decimal value in minutes so seconds will be 0
So, DMS will be 55 degrees 27 minutes 0 seconds
Hence converting angle measure of 55.45 to DMS notation we get 55 degrees 27 minutes 0 seconds

Answer: 
Step-by-step explanation:
<h3><em><u>
The exercise is: "Justin runs at a constant rate, traveling 17 km in 2 hours. Write an equation that shows the relationship between the distance he runs (d) in kilometers and the time he spends running (h) in hours."</u></em></h3>
You know that Justin travels 17 kilometers in 2 hours. With this information you can calculate his speed in kilometers per hour.
The formula to calculate the constant speed is:
Where "d" is the distance and "t" is the time.
Substiuting values, you get:
By definition:
Since the time Justin spends running is represented with "h" in the exercise, this is:
Substituting the value of "V" into , you get that the equation that shows the relationship between the distance he runs (in kilometers) and the time he spends running (in hours), is:
