Complete Question
The mean quiz score for 8 students is 50. The scores for 7 of the 8 students are shown below:
20, 20, 20, 30, 80, 80, 80
What is the score for the remaining student?
Answer:
70
Step-by-step explanation:
The mean quiz score for 8 students is 50.
The total score of the students is
Mean × Number of students
Total score of the students = 50 × 8
= 400
From the attached image, and the question above, the scores of the students were given in a dot plot
and interpreted as:
20, 20, 20, 30, 80, 80, 80
Hence, the total scores of the 7 students is
20 + 20 + 20 + 30 + 80 + 80 + 80
= 330
The score of the 8th and remaining student is calculated as:
400 - 330 = 70

Answer:
1.96 planes
Step-by-step explanation:
The computation of the number of planes is shown below:
As we know that
System Inventory is
= Flow rate in the system × Throughput time
where,
Flow rate is
= Frequency of taken off
= 16 planes ÷ hour
= 16 ÷ 60 Planes per minute
Throughput time is
= runway waiting time + runway Run time
= 33 seconds + 6 minutes × 60 seconds + 48 seconds
= 441 seconds
= 441 per 60 seconds
Therefore the number of planes is
= 1.96 planes
