It would probably be 675 cause i did it and got that
Answer:
.
Step-by-step explanation:
Start by finding the slope of this line.
If a slanting line goes through 
and 
, where 
, the slope of this line would be:
.
The line in this question goes through 
and 
. Hence, the slope of this line would be:
.
If a slanting line with a slope of 
and goes through the point , the equation of this line in the point-slope form would be:
.
For the line in this question, the slope is 
. Take as the chosen point on this line. The point-slope form equation of this line would be:
.
Rewrite to obtain the equation of this line in the slope-intercept form:
.
Before outlier : 7.25
After outlier : 4
7.25 - 4 = 3.25
So the mean decreases by 3.25 when the outlier is removed.
Answer:
n = 4
Step-by-step explanation:
36 = 13n - 4n
<=> 36 = (13-4).n
<=> 36 = 9n
<=> n = 36 / 9
<=> n = 4
