Answer:
a) 19 students
b) the mean 3 9/19
the median 3
the mode 3
c) the range 6
Step-by-step explanation:
The data set shows that
0 points gets 1 student,
1 point gets 1 student,
2 points get 2 students,
3 points get 6 students,
4 points get 4 students,
5 points get 3 students and
6 points get 2 students.
a) There are 1+1+2+6+4+3+2=19 students.
b) The mean is

The average score is 3 9/19 points.
The median is 10th term in the data set - 3 points (means the middle score in the data set)
The mode is 3 points (means most happened score)
c) The range of the data is 6-0=6 points.

<span>Hello : let
A(-4,5) B(-5,-4)
the slope is : (YB - YA)/(XB -XA)
(-4-5)/(-5+4) = -9/-1=9
an equation is : y=ax+b a is a slope</span>
y = 9x +b
the line through point A(-4,5) :
5 = 9(-4)+b<span>
<span>b =41
the equation is : y =9x+41</span></span>
