Answer:
3N + 25M + P ≤ 45
Explanation:
Let the number of Newspaper Stories taken=N
Newspaper stories take 3 hours to write.
Total Hour spent on Newspaper Stories=3N
Let the number of Magazine Articles taken =M
Magazine articles take much longer to write 25 hours per article.
Total Hour spent in Magazine Articles=25M
Let the number of Proofreading jobs taken =P
Proofreading pays for every 1 hour
Total Hour spent in Proofreading jobs=P
Since both newspaper stories and magazine articles must be completed in the week they are started.
The writer doesn't want to work more than 45 hours per week. So his total hour in a week is less than or equal to 45.
The Constraint that limits the amount of time the writer will work in a week is given as:
3N + 25M + P ≤ 45
Answer:
North Park $13,000 $16,000 N
Upper River Beach 6,000 8,000 Y
South Shore 29,000 30,000 Y
Green Creek 900 1,300 N
Explanation:
The cleanup will happen in the area where the marginal benefit is more than the marginal cost. the North park will not be cleaned up. River beach will be cleaned Up. South shore will be cleaned up. Green creak will not be cleaned up.
Answer: Both ‘8.2%’ and ’14.6%’ are descriptive statistics.
Descriptive statistics summarize and describe the features of the data in a study or survey numerically.
In this question, the information just tells us the percentage of people who had a particular opinion for a given question. Hence these percentages describe the data.
Answer: Nominal
Explanation:
When the Nominal measurement scale is used, it means the data was sorted into labels or names which is why it is sometimes referred to as Named data. For instance, sorting dogs in a park into their species i.e Husky, American Bull, German Shephard etc.
There is no quantitative value and usually there is no ordering method to this measurement scale.
The professor sorted her students according to their majors which in this case acted as labels so the Professor was using the Nominal measurement scale.
