18+30=48
48+40=88
88+40=128
128+50=178
Thats all i found so far in the pattern
30,40,40,50 
then it drops
by 140 then adds by 30..
I dont know how else to explain it

Step-by-step explanation:
Rate of change = final - initial / time(in years) 
= 41 - 43 / 2014 - 2012
= - 2 / 2
<u>Rate of change</u> = <u>- 1</u>
Therefore, the number of employees with health care benefits reduced by 1 person per year between 2012 - 2014 in response to policy changes. 
 
        
             
        
        
        
The answer is 280 because if you multiply 400 by .3 you get 120 and if you subtract 120 from 400 you get 280
        
                    
             
        
        
        
Answer:
b= -4.68
Step-by-step explanation:
Hello!
We have to study variables:
Y: Monthly coffe sales
X: Price per pound of coffe ($)
The estimate regression line is
^Yi= a + bxi ∀ (i=1,.....,10)
The slope of the estimated regression line is represented by b.
The formula I'll use to calculate it is:
b= [n∑xiyi -(∑xi)*(∑yi)]/ n∑xi²-(∑xi)²
To calculate b we need to do some auxiliary calculations:
∑xiyi= 4213.15
∑xi= 87.47
∑yi= 545
∑xi²= 883.3703
Then we replace the formula:
b= [10*4213.15-(87.47)*(545)]/ n883.3703-(87.47)²
b= -4.68
I hope you have a SUPER day!
