yes because when filling in the unknown (3*2-4=2) gets you the answer of 2.
 
        
                    
             
        
        
        
Answer:
b) median: there are 7 numbers listed; 20 is the middle number among them
range: subtract lowest from highest number 25-2=23
mean: add all the numbers together =129
mode: place numbers in order (smallest to greatest), then see which number appears the most 2, 18, 18, 20, 22, 24, 25=18

Answer:
   (a)  2%
Step-by-step explanation:
A score of 60 is 2 standard deviations below the mean (80 -2·10 = 60). The empirical rule tells you that 95% of the distribution is within 2 standard deviations of the mean. The remaining 5% is split evenly between those that are more than 2 SD above the mean and those that are more than 2 SD below the mean.
That tells you the percentage who failed is about 2.5%. The best answer choice is 2%.
_____
<em>Additional comment</em>
The empirical rule is a little bit sloppy, but it gets you in the ballpark. The actual percentage is closer to 2.275%.
 
        
             
        
        
        
To solve this, you need to isolate/get the variable "x" by itself in the inequality:
2(1 - x) > 2x     Divide 2 on both sides

1 - x > x     Add x on both sides to get "x" on one side of the inequality
1 - x + x > x + x
1 > 2x        Divide 2 on both sides to get "x" by itself
 or
  or   (x is any number less than 1/2)
     (x is any number less than 1/2)
[Another way you could've solved it]
2(1 - x) > 2x     Distribute 2 into (1 - x)
(2)1 + (2)(-x) > 2x
2 - 2x > 2x      Add 2x on both sides
2 - 2x + 2x > 2x + 2x
2 > 4x    Divide 4 on both sides to get "x" by itself
