Step-by-step explanation:
Given that:
The ratio of band students to choir students is 4 : 6.
Total number of students in the band and choir combined = 60
To find:
The number of students in the band = ?
Solution:
First of all, let us understand the meaning of the ratio given.
Ratio of 4 : 6 means there are 4 number of band students for every 6 number of choir students.
Also, number of band students will be in the multiples of 4 only and
number of choir students will be in the multiples of 6 only
Let the total number of band students = 4
Let the total number of choir students = 6
Total number of students = 60
As per question statement, we can write the following equation:
Total number of band students = 4 6 = <em>24</em>
Using weighed averages, it is found that:
- The final grade is 91.
- The final grade is 66.8.
- The higher grade would be 79.55, with the second grading scheme.
- On average, she sold $48,280 per day.
- On average, she makes $12.5 per hour.
---------------------------------------
To find the weighed average, we multiply each value by it's weight.
---------------------------------------
Question 1:
- Grade of 91, with a weight of 67%.
- Grade of 91, with a weight of 33%.
Thus:
The final grade is 91.
---------------------------------------
Question 2:
- Grade of 83, with a weight of 40%(highest grade).
- Grade of 60, with a weight of 30%.
- Grade of 52, with a weight of 30%.
Thus:
The final grade is 66.8.
---------------------------------------
Question 3:
With teacher 1:
- 75 with a weight of 25%.
- 80 with a weight of 10%.
- 85 with a weight of 40%.
- 62 with a grade of 25%.
Thus:
---------------------------------------
With teacher 2:
- 75 with a weight of 15%.
- 80 with a weight of 10%.
- 85 with a weight of 60%.
- 62 with a weight of 15%.
Thus:
The higher grade would be 79.55, with the second grading scheme.
---------------------------------------
Question 4:
- Average of $36,432, with a weight of
- Average of $51,834, with a weight of
Thus:
On average, she sold $48,280 per day.
---------------------------------------
Question 5:
- Average of $14.84, with a weight of
- Average of $10.76, with a weight of
Thus:
On average, she makes $12.5 per hour.
