$322.56
You change 28% to .28 then multiply that with $448=$125.44 
Then you minus that from $448=$322.56
        
                    
             
        
        
        
If you're going to around the 487 to the nearest hundredso are you around the next number be if after itso that would be 500
        
                    
             
        
        
        
The question is asking to find the variance for the said samples in the problem ans use the sample data to determine each variance, and base on my further computation and further calculation, I would say that the answer would be the following:
#1. 3.3 -> 1 and 3 -> 2/9
#2. 1-> 0->3/9
#3. 6.3 - > 8 and 3-> 2/9
#4 49-> 1 and 8-> 2/9
        
             
        
        
        
Answer:
after 10 seconds
Step-by-step explanation:
h=-16t^2+v0*t+h0
ground level is h0 with a measure of 0
160 is v or velocity
0=-16t^(2)+160t+0
0=-16t^(2)+160t
0=16t(-t+10)
0/16t=(-t+10)
0=-t+10
-10=-t
10=t
t=10
 
        
             
        
        
        
The digit in the ten thousands place is printed slightly to the left 
of the one in the thousands place.
If they are the same digit, then the value of the one on the left is 
ten times the value of the one on the right.
