Answer:
Step-by-step explanation:
The point slope form of a line is 
where 
. We write
Convert point slope form to slope intercept form by simplifying and rearranging.
Add 't' to both sides. t+r=s
Step-by-step explanation:
No of people not from their neighborhood=25-20=5
total contact s=25
therefore probability to call a person not from his neighborhood=5/25=1/5
therefore P=1/5
Let x be the number.
Set up an equation:
2x - 2/3x = 20
Simplify:
1 1/3x = 20
Divide both sides by 1 1/3
X = 15
The number is 15
Answer:
It may be 9
Step-by-step explanation:
Solution:
Here,
Median = n+1/2th term
=5+1/2 th term
=6/2 th term
=3rd term
Now,
Arranging the data in ascending order...
Since, 9 is the third term. So, 9 is the median.....
