A) 0.2076
B) 0.6786
C) 0.3214
Explanation:A) 

B) We find the probability that X=6, 7, or 8:

C) P(X≤5) = 1-P(X>5) = 1-0.6786 = 0.3214
 
        
        
        
Answer:
Step-by-step explanation:
Find the multiples of 2x^2 and 2
for 2x^ you get 2,1 but they need to have x  to get x^2 so; (2x and x)=2x^2
for 2 you get 2,1 (2x1)=2 
Because your equation has a 5x and no negatives you know that your factors need to be positive.
(2x+1)(x+2)
when you multiply these you get
2x^2+4x+x+2 (remember 2x multiplies with everything inside (x+2) = 2x^2+4) and so on for the x (x+2) =x+2 )
Then you combine like terms 4x+x=5x
and those are the only like terms available and you get
2x^2+5x+2

Answer:
y = 7x - 3
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
y = 7x - 3
 
        
             
        
        
        
There are at least a few ways to express it, one of them being:
<u>p' = p + 0.075p</u>
p' is for population in the upcoming year.
0.075 is as much as 7.5%, so we just add current population and the value of expected increase.
