A day care program has an average daily expense of $75.00. The standard deviation is $5.00. The owner takes a
sample of 64 bills. What is the probability the mean of his sample will be between $70.00 and $80.00?
Step 1. Calculate a z-score for $70.00
Step 2. Give the probability for step 1.
%
Step 3. Calculate the z-score for $80.00
Step 4. Give the probability for step 3.
%
Step 5. Add the probabilities from steps 2&4.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
