Solve using simplex method
Maximize z= 21x+15x
Subject to the constraints - x - 2x >_ - 6
how many different elements does A x B have if A has m elements and B has n elements?
If A = {5,6,7} and B = {2,3}, {(2,6),(2,5),(3,7)} ⊆ B×A.
Find A x B if A={0,1,3} and B={1,2,a,b}.
INTERVAL ESTIMATE
4. Suppose that the amount of time spend by working student weekly is normally distributed with the standard deviation of 25 minutes. A random sample of 125 observations is drawn and the sample mean is computed as 150 minutes. Determine the 95% confidence interval estimate of the population mean.

SAMPLE SIZE DETERMINATION
3. A bread shop owner wishes to find the 95% confidence interval of the true mean cost of special bread. How large should the sample be if she wishes to be accurate within ₱8? As previous study showed that the standard deviation of the price was ₱12.
