Answer:
 x=60 and the missing angle is 140
Step-by-step explanation:
40 × 2x + 20= 180
60 + 2x =180
 2x=120 
 x=60
 2(60)+20=140
 
        
             
        
        
        
#2 is 35°C (just plug in 95 to the formula)
#3:
in the left column are:
(8x-(6+y))
(3/4)w+x^2
in the right column are:
y^2-0.5w
w/4+3(x+y)
to solve you just plug in to the formula
        
             
        
        
        
Find the probability of rolling a number bigger than 4 and subtract that by 100%; 
P(5)= 1/6 <-- 6 possible outcomes, 1, 2, 3, 4, 5 or 6
P(6)= 1/6 
You could have rolled a 5 or 6. When the word or is used, the probabilities are added together, when and is used, they are multiplied. 
(1/6)+(1/6)=2/6 
1-P(5)+P(6) 
=1-(2/6) 
=(6/6)-(2/6)
=4/6 
Therefore the probability of not rolling a number larger than 4 is 4/6 or 2/3.
Hope I helped :) 
        
             
        
        
        
Answer:
Step-by-step explanation:
The closer the line of best fit is to the points the more accurate it is.  The correlation coefficient gives a numerical rank, where 1 is a perfect fit and the closer to 0 it is the less accurate it is.
I need the values of the line at the same x values as the scatterplot points.  After you have that take the difference of the value of the line of best fit and the corresponding scatterpoint.  if the point is higher than the line then the resiual will be negative and if the point is lower the residual will be positive.  Do you have the equation of the line of best fit?
