Answer: 4.15
Step-by-step explanation:
Mean is calculated by total sum of student records/ number of students records
From the question, total sum is 83, while the number of students records is 20
Divide 83 by 20 to get the mean
Mean = 83/20 = 4.15

Answer:
The linear function is 
.
Step-by-step explanation:
A linear function is given by the formula,
, where m is the slope and c is the y intercept of function.
The following two points lie on the graph; (0,-1) and (3,-10)
Inserting this two points we get,
,
solving this two equations we get,
m = -3 and c= -1
Thus, the linear function is given by,
