We have to find the number of ways an employer send 3 employees to a job fair if she has 11 employees.
This is the problem from combination.
The formula for combination is given by

Here, n= 11, r= 3
Therefore, total number of ways is given by

A is the correct option.
Answer:
63
Step-by-step explanation:
Because, 100% of 70 would be 7. Now we have that number lets multiply it by 9 because of 90%. 9 x 7 = 63 first-graders
Answer:

Step-by-step explanation:
subtract 12x from both sides, then divide by twelve.
Answer: False
Step-by-step explanation:
Triangle is a polygon with 3 sides. The formula for calculating the sum of angle in a polygon is given as :

where n is the number of sides , so to calculate the sum of angles in a triangle we have :

= 1 x 180
= 180
Therefore : The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 180 degrees.
