Answer:
The correct value is t* = 2.797.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a  two-tailed confidence level of  . So we have T = 2.797.
. So we have T = 2.797.
 
        
             
        
        
        
Answer:
x=2 , y = 1
Step-by-step explanation:
x + 2(2x-3) = 4
x+4x-6=4
5x-6=4
5x= 10
x=10/5
x=2
subs x=2 into x +2y=4
2+2y=4
2y=2
y=2/2
y=1
 
        
                    
             
        
        
        
So 
1 gallon = 4 quarts 
1 quart = 2 pints
g = 4q = q + q + q + q
g = 2p^+2p^+2p^+2p^ 
 1 gallon equals 8 pints
2 gallons equal 16 pints
 THe answer is 16 pints
        
             
        
        
        
Answer:Idea
Step-by-step explanation:Hey! An idea would be climate change or air pollution. Our carbon footprint and many other things such as the use of cars affect it. Good luck!
