My question showed a bar graph showing the number of days of class 20 students missed. "What is the average number of days that each student missed?"
A) 1
B) 1.5
C) 1.7
D)2
E)2.3
**The answer's 1.7 (according to my teacher), but from solving it I either got a 1.5 or 2. Please help.
I dont have the graph, but you get average by taking days missed and dividing by 20
So, the choices are just wrong?
Eunice. How can I tell? I have no idea what the graph indicates.
Did you do what bobpursley suggested?
To find the average number of days that each student missed, you need to calculate the mean. Here's how you can do it:
1. Look at the bar graph and determine the number of days missed by each student. Add up all the values to find the total number of days missed by all 20 students.
2. Divide the total number of days missed by the number of students (which is 20 in this case). This will give you the average number of days missed.
For example, let's say the total number of days missed by all students is 34.
Average = Total days missed / Number of students
= 34 / 20
= 1.7
So in this case, the average number of days missed per student is 1.7.
Based on this calculation, the correct answer would indeed be C) 1.7. Double-check your calculations and make sure you've correctly added up the number of days missed by each student before dividing by the total number of students.
