Answer:
first blank is 7
next blank is 20
Step-by-step explanation:
because 14 divided by 2 is 7
-4×5=20
 
        
                    
             
        
        
        
Answer: y = 85 2) 36.222°
Step-by-step explanation:
281 + 268 + 225 + 290 = 1064
1064 / 7 = 152
152 x 12 = 1824
392 + 512 + 413 + 422 = 1739
1824 - 1739 = 85
Therefore y = 85
 
        
             
        
        
        
They aren't similar because they're not proportional (the sides do not form equal ratios)<span />

We are asked to determine the correlation factor "r" of the given table. To do that we will first label the column for "Quality" as "x" and the column for "Easiness" as "y". Like this:
Now, we create another column with the product of "x" and "y". Like this:
Now, we will add another column with the squares of the values of "x". Like this:
Now, we add another column with the squares of the values of "y":
Now, we sum the values on each of the columns:
Now, to get the correlation factor we use the following formula:

Where:

Now we substitute the values, we get:

Solving the operations:

Therefore, the correlation factor is 0.858. If the correlation factor approaches the values of +1, this means that there is a strong linear correlation between the variables "x" and "y" and this correlation tends to be with a positive slope.
