(12,200 + 16,211 + 12,050 + 11,350 + 13,325) / 5 = 65136/5 = 
13027.2 <== this is the mean (average)
11,350 , 12,050 , 12,200 , 13,325, 16,211
median (middle number) = 12,200
there is no mode...a mode is a number that appears most often...all the numbers appear once in this data.
        
                    
             
        
        
        
I don't know if that is factor-able. It looks like you could just subtract and get 64t. which would lead to the answer being zero since you divide by zero when isolating the variable t.
        
             
        
        
        
Answer:
35 quizzes
Step-by-step explanation:
We need to determine how many ways we can choose 4 questions out of 7 to make the quizzes. 
We do this by using the formula  which describes the number of ways we can choose
 which describes the number of ways we can choose  objects given
 objects given  possible choices. So, if
 possible choices. So, if  and
 and  , then:
, then:

Hence, the teacher can make 35 different geometry quizzes.

Given:

To find:
Which statement are true?
Solution:
Option A: The entire expression is a sum.
It is true because it performed addition operation.
Option B: The coefficient of s is 3.

It is not true because the coefficient of s is  .
.
Option C: The term  is a quotient.
 is a quotient.
If we divide 7 by r, we obtain a quotient.
So it is true.
Option D: The term  has a variable.
 has a variable.
It is not true because it does not contain any variable.
Therefore the entire expression is a sum and the term  is a quotient are true statement.
 is a quotient are true statement.
