Answer:
<h2>
The mean decreases, and the median remains the same.</h2>
Step-by-step explanation:
Remember that a box plot is made by the quartiles of the distribution, the maximum value and the minimum value. So, from a box plot we can deduct the range, the median and the interquartile range.
In this case, the median remains the same at $9.5 per hour. The median is indicated by the middle line of the box, and you can observe that it doesn't change.
Now, the range of the data set decreases from 7 to 3.
On the other hand, the mean must decrease, because data greater than $11 doesn't exist in the box plot number 2, and the mean is a central measure sensible to those changes.
Therefore, the right answer is <em>The mean decreases, and the median remains the same.</em>
 
        
             
        
        
        
Answer:
1) E and F
Step-by-step explanation:
So width is x
legth Is 3x+3
Perimeter is 
3x+3+3x+3+x+x
Now simplify
8x+6
Now go through each choice that equals 8x+6
Only e and f
 
        
                    
             
        
        
        
Y=7 because there is no slope and the Y intercept is at 7.
        
             
        
        
        
The answer is C, you can do this by doing FOIL
        
                    
             
        
        
        
Answer:
-1/21
Step-by-step explanation:
2/3 + -5/7
Get a common denominator of 21
2/3 *7/7 = 14/21
-5/7*3/3 = -15/21
14/21 - 15/21 = -1/21
