Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Using algebraic adjustments, convert the formula (picture) to a disjunctive normal form.
Will you spot a mistake? Can the answer be only negative y? What about x? Can it just disappear? What does it mean?
Thank you!

- In winter of a country, it rains 45% of the days and shine 55% of the days. Mr. X has abarometer which wrongly predicts 5% of the time in rainy days and 10% on shiny days.Mr. X does not carry umbrella if barometer predicts shine. On good shiny morning inwinter, his barometer predicts “shine” and he does not carry umbrella. What is theprobability that Mr. X will suffer from rain on that day.We now need to attempt to find an exact value for n such that P(r ≥ 1) = 0.99. Clearly, if the bank has any chance of detecting a burglar they will need to have at least one alarm installed. So, we know that, minimally, n must be at least 1.Since n must be at least 1, suppose we start by trying n = 2, where there will be two alarms. When there are two alarms, r ≥ 1 means either one or both alarms could detect the burglar. If neither alarm detects the burglar it is considered a failure. Therefore, P(r ≥ 1) can be calculated using either of the following formulas. P(r ≥ 1) = P(1) + P(2) P(r ≥ 1) = 1 − P ( ___ ) fill in the blank36. Over the last three years, a portfolio manager investing in large cap stocks had an average return of 25% when the small cap benchmark he selected returned 19.5%. Is the performance consistent with efficient market hypothesis? a. No, it is not. It is a violation of weak form EMH. b. No, it is not. It is a violation of semi-strong form EMH. c. No, it is not. It is a violation of strong form EMH. d. No, it is not. It is a violation of all forms of EMH. e. Yes, it could be. The manager selected an inappropriate benchmark.

- Hypertension A national study found that treating people appropriately for high blood pressure reduced their overall mortality by 20%. Treating people adequately for hypertension has been dif- ficult because it is estimated that 50% of hypertensives do not know they have high blood pressure, 50% of those who do know are inadequately treated by their physicians, and 50% who are appropriately treated fail to follow this treat- ment by taking the right number of pills. 1 If the preceding 50% rates were each reduced to 40% by a massive education program, then what effect would this change have on the overall mortality rate among true hypertensives; that is, would the mortality rate decrease and, if so, what percentage of deaths among hypertensives could be prevented by the education program?It took 65 million years from the time the dinosaurs were wiped out by an asteroid impact until humans arrived on the scene. Today, we have technology that could wipe out all humans if we do not use it wisely. Suppose we wipe ourselves out, and it then takes 65 million years for the next intelligent species to arise on Earth. Then suppose the same thing happens to them, with another intelligent species arising 65 million years later. If this process could continue until the Sun dies in about 5 billion years, how many more times could intelligent species arise on Earth at 65-million-year intervals?Suppose that there are 4 deaths due to stomach can- cer among workers in a tire plant from 1/1/64 to 12/31/83, while 2.5 are expected based on U.S. mortality rates. Provide a 95% CI for the expected number of deaths from stomach cancer over 20 years among the tire workers. Is the number of cases of stomach cancer excessive?
