It has been claimed that, for a penny minted in 1999 or earlier, the probability that a spinning penny will fall with heads facing up is p=0.30. Three students got together, and they would each spin a penny and record the number X of heads out of three spins. They repeated this experiment n=200 times, observing the following data: X= 0, 1, 2, 3 for 68, 77, 49, and 6 times respectively. Using these data, we shall use a chi-square...

1. Diazepam, has 3 rings, 8 double bonds, and the formula C16H?ClN2O. How many hydrogens does Diazepam have? (Calculate the answer, don't count) I know that 3 rings = 3 Du and 8 double = 1Du, thus there is 11 Du I'm confused on what to do next, the book has C16H34-H22= C16H12 ----->answer is C16H13ClN2O How do you use the 11Du to calculate the number of Hydrogens?

Suppose a punched card has 80 columns and 12 rows. (a) If any number of holes can be punched in the card, how many different cards can there be. If more convenient, you may give your answer in the form of an expression. (b) If no column can have more than 2 holes, how many different cards can there be? Again, give your answer in the form of an expression if that is more convenient.
