Answer:
2.765 miles
Step-by-step explanation:
Speed = 6 mph = 6 mile per hour
Time = 27:39, which means 27 minutes and 39 seconds.
So in order to find the distance Parker ran, first we need to convert this time to hours.
There are 60 minutes in 1 hour and 60 seconds in 1 minute. So to convert minutes to hour, we divide the by 60. To convert seconds to hour we divided them by 60 twice, once for converting them to minutes and then to second.
So,
27 minutes and 39 seconds = hours
Since, Distance is defined as:
Distance = Speed x Time
The distance hat Parker ran would be:
Distance = miles
This means Parker run for 2.765 miles
18x6 = 108

Answer:
Step-by-step explanation:
In a simple random sample, every member of the population has an equal chance of being selected.
Your sampling frame should include the whole population. To conduct this type of sampling, you can use tools like random number generators or other techniques that are based entirely on chance.
Biased sample
A sample is biased if individuals or groups from the population are not represented in the sample.
In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability than others.
Affects
It affects the internal validity of an analysis by leading to inaccurate estimation of relationships between variables. It also can affect the external validity of an analysis because the results from a biased sample may not generalize to the population.
The probability would be 3:75 or 3/75. If you want a percent, that's 4%.
Answer:
The average final score = 82.58
Step-by-step explanation:
we have given,
Grading Scale 1 has the following weights :-
Tests- 50% , Quiz- 25% , Homework- 15% and Final Exam- 10%
Total % marks obtained in tests = = 81.33%
Total % marks obtained in quiz = = 83.66%
Home work score = 90
final exam score = 75
Now, Weight of tests grade = 50% of 81.33 = 40.665
Weight of quiz grade = 25% of 83.66 = 20.915
Weight of homework = 15% of 90 = 13.5
Weight of final exam = 10% of 75 = 7.5
So the average final score = 40.665 + 20.915 + 13.5 + 7.5 = 82.5
