The expression that can be used to approximate the expression below is
- Given the logarithmic function expressed as
, we need the log expression that is equivalent to the given expression.
- To do this, we will write the logarithm as a quotient to the same base. Using the base of 10, the expression can be written as;
This is similar to the option c where the base of "b" was used as

I looked the question up on google ;)
There are 
ways of getting exactly 5 heads in 10 tosses. There are 
possible outcomes. So the probability of getting exactly 5 heads is
To help with thinking about this, we can say that the 6 gallons of 50% acid contains 3 gallons of pure acid and 3 gallons of filler. This would make the concentration 3/6, or 50%. Adding a gallon of pure acid would shift the concentration to 4/7, or 57.1%.
When the relationship becomes 70%, four gallons of pure acid have been added.
3+4 7
—— = — = 70%
6+4 10
