Answer: 165 ways
Step-by-step explanation:
The process of selection is done by using the combination formula for selection. If given "n" items and we are to choose "r" items from this given "n", the formula to use is denoted by:
nCr. = n! /(n-r)! × r!
Where
n! = n * (n-1) * (n-2)... *3*2*1.
In this case the number of items given = 11
And the number of items to be chosen = 3,
Hence the number of ways to do this = 11C3= 11!/(11-3)! × 3!
=165 ways.
The answer is 16.25 adding all of those up

If u have a open circle, then the inequality has no equal sign. But if it is a closed circle, the inequality has an equal sign.
Shading to the left means " less then " .
Shading to the right means " greater then " .
(1) u have an open circle on -7 with shading to the left....
x < -7
(2) u have a closed circle on 4.5 with shading to the left....
x < = 4.5 (thats less then or equal)
(3) u have an open circle on -5 with shading to the right...
x > -5
(4) u have an open circle on 1.5 with shading to the right...
x > 1.5
