Joe loves going out to eat at area restaurants. Her favorite foods are Mexican, Italian, Chinese and Thai. On average, Joe pays $10.00 for a Mexican meal, $15.00 for an Italian meal, $9.00 for a Chinese meal, and $11.00 for a Thai meal. Joe's eating habits are predictable: There is a 70% chance that today's meal will be a repeat of yesterday's and an equal chance that he will switch to one of the remaining three. How often does Joe eat Mexican food?

I really appreciate the help on this question as well it is a FRQ AP STAT question
A man buys a racehorse for $25,000 and enters it in two races. He plans to sell the horse afterward, hoping to make a profit. If the horse wins both races, its value will jump to $105,000. If it wins one of the races, it will be worth $65,000. If it loses both races, it will be worth only $10,000. The man believes there is a 30% chance that the horse will win the first race and a 35% chance that it will win the second one. Assuming that the two races are independent events, find the man's expected profit.
A consultant came up with a new system to increase productivity at your office. When you compared those who followed the system to those in a different office who did not adopt the system, the p-value for the comparison is 0.85. Is this system helpful? A. Probably B. It would depend on how the other office does it when it adopts the system. C. Not likely. D. Even knowing how the other office would do if the system were adopted, there is not enough information to answer the question.
A citrus grower anticipates a profit of $100,000 this year if the nightly temperatures remain mild. Unfortunately, the weather forecast indicates a 25% chance that the temperatures will drop below freezing during the next week. Such freezing weather will destroy 40% of the crop and reduce the profit to $60,000. However, the grower can protect the citrus fruit against the possible freezing (using smudge pots, electric fans, and so on) at a cost of $5000. Should the grower spend the $5000 and thereby reducethe profit to $95,000? [Hint: Compute E(X ), where X is theprofit the grower will get if he does nothing to protect the fruit.]
College admissions For high school students graduatingin 2007, college admissions to the nation’s most selectiveschools were the most competitive in memory. (The NewYork Times, “A Great Year for Ivy League Schools, butNot So Good for Applicants to Them,” April 4, 2007).Harvard accepted about 9% of its applicants, Stanford10%, and Penn 16%. Jorge has applied to all three.Assuming that he’s a typical applicant, he figures that hischances of getting into both Harvard and Stanford mustbe about 0.9%.a) How has he arrived at this conclusion?b) What additional assumption is he making?c) Do you agree with his conclusion?
The past records of a supermarket show that its customers spend an average of $110 per visit at this store. Recently the management of the store initiated a promotional campaign according to which each customer receives points based on the total money spent at the store, and these points can be used to buy products at the store. The management expects that as a result of this campaign, the customers should be encouraged to spend more money at the store. To check whether this is true, the manager of the store took a sample of 14 customers who visited the store. The following data give the money (in dollars) spent by these customers at this supermarket during their visits. 106.13 107.43 124.68 124.88 101.17 72.75 85.45 86.05 100.4 98.84 101.63 95.56 89.40 119.52 Assume that the money spent by all customers at this supermarket has a normal distribution. Using a 2.5% significance level, can you conclude that the mean amount of money spent by all customers at this supermarket after the…

According to a study administered by the National Bureau of Economic Research, half of Americans would struggle to come up with $2000 in the event of a financial emergency. The majority of the 1900 Americans surveyed said they would rely on more than one method to come up with emergency funds if required. In the survey, 397 people said that they "certainly" would not be able to cope with an unexpected $2000 bill if they had to come up with the money in 30 days, and 553 people said they "probably" would not be able to cope. Step 1 of 2 : What percentage of Americans "certainly" would not be able to produce $2000 in the event of an emergency according to the study? Round your answer to one decimal place, if necessary.
