The answer is 240 :3
60+60= 120
120+60 = 180 
and 60 more would be 240 
60 fours would be 240
3  60's  would be 180.  So your answer is 240

Answer:
Step-by-step explanation:
1st draw 3 circles where each center is on one of the points,  and the other side , the drawing side of the compass is on another point.. the draw the circle ... do that for each point... there will be one point.. where all three cross some where in the middle.. put the point of your compass on that point.. and then put the drawing side on any one of the points... all 3 will now be on the circle.. draw it.. :)  
 
        
             
        
        
        
Answer:  The mode is: 3 .  The range is:  6 .
___________________________________
Explanation:
___________________________________
  It would be best to list this values in the data set given, from least to greatest:
________________________________________________
  { 3, 3, 3, 3, 4, 5, 5, 6, 9 } .
________________________________________________
  The mode is the number that occurs most frequently in the data set, which is: "3". 
_________________________________________________________
{The number, "3", occurs FOUR (4) times.  The number, "4", occurs ONE (1) time.  The number, "5", occurs TWO (2) times.  The number, "6", occurs ONE (1) time.  The number, "9", occurs ONE (1) time.}.
___________________________________________________
The range is calculated from subtracting the LOWEST value in the data set FROM the HIGHEST value in the data set.
____________________________________________________
 The lowest values in the data set is: "3" .
 
 The highest value in the data set is: "9" .
________________________________________________
 To calculate the range:  9 <span>− 3  = 6 .  The range is:  "6".
</span>________________________________________________
  Answer:  The mode is:  3 .  The range is:  6 .

Answer:
B) μD = 0.60 ± 0.10(1.397)
Step-by-step explanation:
The confidence interval is given by:

Where
MD=60
n=9
df=n-1=8


Then the confidence interval is
μD=0.60±1.397*(0.3/√9)
μD=0.60±0.10*(1.397)
