Answer:
y= x-4
Step-by-step explanation:
Since we have a point, and the slope, we can use the point slope formula 

m is the slope, y1 is the y coordinate of the point and x1 is the x coordinate of the point. 
We know that m is 1, y1 is 1, and x1 is 5, so we can substitute them in 
y-1=1(x-5) 
Solve for y by isolating it 
Distribute the 1 
y-1=1*x+ 1*-5 
y-1=x-5 
Add 1 to both sides 
y=x-4
 
        
                    
             
        
        
        
Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H0:  p1 - p2=0
Ha:  p1 - p2  ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%.  So our critical values are:  z > 2.575  and z < -2.575

Step-by-step explanation:
this is an arithmetic sequence :
a1 = 1
an = an-1 + 2 = a1 + (n-1)×2
the sum of n terms of an arithmetic sequence is
S = n×(a1 + an)/2
n = 5000
an = a1 + 4999×2 = 9999
S = 5000×(1 + 9999)/2 = 5000×5000 = 25,000,000
