gar12,    mean is another word for average  

thanks saseflower   

Yea they are pretty cheap too.  I wonder if they have 2 heads or something.   

They say 2 heads are better than 1 - maybe they have only go a half a head.      

Makes sense to me - thanks anon 

multiply by 100 and put a percent sign   

For the x intercept put y=0 and solve

For the y intercept put x=0 and solve

$$\\log_x16=-2\\\\
16=x^{-2}\\\\
\frac{1}{16}=x^{+2}\\\\
x=\frac{1}{4}$$

saseflower, you have to put the 15a in brackets   otherwise it is divide y 15 then multiply the answer by a.

Otherwise you answer is excellent - as it always is - thank you.:)
