Answer:
 366 muffins
Step-by-step explanation:
28 x 12 = 336
5 x 6 = 30
336 + 30= 366 muffins
 
        
             
        
        
        
Answer:
Find the slopes; 123 servings
Step-by-step explanation:
When you look at the graph and table, find out which ones have a slope of 1/2
To find slope you have to use this equation

So for each graph and table, calculate the slope using that formula :)
For the second question, 
For every 10 students, the amount of juice dispensed was
7*4 + 3*8 = 52
So divide 52 by 10 to get 5.2
Then divide the total amount of juice (640) by 5.2 and that rounds to about 123 servings of juice
 
        
             
        
        
        
Answer:
The sample size is too small
Step-by-step explanation:
The answer is the last one: the sample size is too small. Since we only got 3 subjects to test, maybe one of them could live for a long time after the diagnosis of Cacer and that made the average survival time go up by a lot. 
In order to obtain results with a significance level higher, you need a sample size of at least 20 subjects. 
Now lets see why other options wouldnt be good answers:
- For a small amount of subjects, it is unlikely to have errors in caculation
- The sample size is given
- We are not given information about the treatment and we dont even know if the subjects feel more confident with the new treatment. Also, if a Placebo effect works regularly, it shouldnt limit statistical sifgnificance
- An increase in 2 years is huge in comparison with the previous survival time.
 
        
             
        
        
        
Speed = distance / time
Speed = 120 / 33
Speed = 3.64 miles per hour
