Answer:
-7/2 , 8
Step-by-step explanation:
Given, M(-5,9) be x1 , y1
N(-2,7) be x2, y2
Now,
Using mid point formula
x = x1+x2/2 y = y1+y2/2
= -5-2/2 = 9+7/2
= -7/2 = 16/2
= 8
Answer: Top right graph
Less/more than is a filled in dot.
Less/more than or equal to is an unfilled dot.
So you have
8 digits (number available) to form
3 digit numbers (number selected).
Using the formula

where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.
The number of three digit numbers that can be formed =

=
336 <span>
O R</span>By using the formula

where a is the number of available digits and c is the number of digits to be selected.<span>
