Answer: 8 oz..
1 pound= 16oz if 8oz=1.59 so add it up 4 times 8+8+8+8= 32 which = 2 pounds total 8=1.59 8+8= 1.59x2=3.18 8+8+8=1.59x3=4.77 8+8+8+8/ 1.59x4= 6.36 so all of them eights will = up to 2 pounds and 8 is obviously less

Step-by-step explanation:
Mean = All values added up and divided by the number of values

Median = Put all numbers in order from least to most and use the middle one, if there are two, use the mean of those two
 . The middle ones are 60 & 75 so
. The middle ones are 60 & 75 so 
Mode = The number that repeats more times. In this case none of them repeat.
 
        
             
        
        
        
I'm assuming you meant to say a^3. If so, then
a^3 = a*a*a
a^3 = 5*5*5
a^3 = 125
        
             
        
        
        
add them both then you get the awnser if the four is not a negative. if the four is a negative use division.
