. A woman saved GH¢ 30,000 in a bank A, whose rate was x % per annum and GH¢ 20,000 in another bank B whose interest rate was y % per annum. Her total interest in two years was GH¢ 6,400. If she had saved GH¢ 20,000 in bank A and GH¢ 30,000 in bank B for the same period, he would have gained GH¢ 200 as additional interest. Find the values of X and Y
The U.S. government wants to determine whether immigrants should be tested for a contagious disease, and it is planning to base this decision on financial considerations. Assume that each immigrant who is allowed to enter the United States and has the disease costs the country $100,000. Also, assume that each immigrant who is allowed to enter the United States and does not have the disease will contribute $10,000 to the national economy. Finally, assume that x percent of all potential immigrants have the disease. The U.S. government can choose to admit all immigrants, admit no immigrants, or test immigrants for the disease before determining whether they should be admitted. It costs T dollars to test a person for the disease, and the test result is either positive or negative. A person who does not have the disease always tests negative. However, 10% of all people who do have the disease test negative. The government’s goal is to maximize the expected net financial benefits per…
n the previousyear, at Hub Motors ltd, for a particular model of Mercedes, Nissanand Ford,one could purchase(in millionshillings)all three cars for a total ofKsh 150. This year, due to inflation, the same cars would cost Ksh 161. The cost of theMercedesincreased by 8%, the Nissan by 6%, and the Fordby 12%. If the price of last year’s Nissanwas Ksh 7less than the price of last year’s Mercedes, Use matrix inverse to findthe price of each of the three cars last year
Suppose that in a certain chemical process the reaction time y (hr) is related to the temperature (°F) in the chamber in which the reaction takes place according to the simple linear regression model with equation y = 5.10 − 0.01x and ? = 0.07. (a) What is the expected change in reaction time for a 1°F increase in temperature? For a 12°F increase in temperature? 1°F increase hr 12°F increase hr (b) What is the expected reaction time when temperature is 190°F? When temperature is 240°F? 190°F hr 240°F hr (c) Suppose five observations are made independently on reaction time, each one for a temperature of 240°F. What is the probability that all five times are between 2.58 and 2.82 hours? (Round your answer to four decimal places.)(d) What is the probability that two independently observed reaction times for temperatures 1° apart are such that the time at the higher temperature exceeds the time at the lower temperature?

During a nationwide program to immunize thepopulation against a new strain of the flu, pubic health officials determined that the cost of inoculating x% of the susceptible populatioin would be approximately C(x) = 1.85x/ 100-x million dollars. a. suppose 17 million dollars are available for providing immunication. What percentage of the sesceptible population will not receive immunization? b. If money was not a problem will they be able to provide immunization to the entire susceptible population?
The car manufacturer Edison is the sole producer of electric cars in the market, selling to two different types of customers. All else equal, travelers (type t) prefer batteries that go longer distances between charges and are willing to pay for this luxury. Urban drivers (type u) do not require as great a battery. Edison knows the willingness-to-pay of each type, and that there are q percent of type ts in the market. The willingness-to-pay for each type for different battery sizes are, Vt(k = 100) = $160, 000, Vt(k = 60) = $80, 000, Vu(k = 100) = $100, 000, Vu(k = 60) = $60, 000, where k is the battery life in kilowatt hours (kWh). Producing 60 kWh battery costs $30,000, which is half the cost of a 100 kWh battery. (a) Edison showroom salesmen believe they can perfectly identify (1st/3rd-degree) which type of buyer walks through the door. Find the profit-maximizing prices (pi) and battery sizes (ki). What is Edison’s average profit per customer? (b) It turns out Edison salesmen are…

During a nationwide program to immunize the population against a new strain of the flu, public health officials determined that the cost of inoculating x% of the susceptible population would be approximately C(x)=1.85x /100 − x million dollars. (i) What would it cost to providing immunization to the first 20% of the susceptible population?(ii) What would it cost to providing immunization to the next 30% of the susceptible population?(iii) Suppose 17 million dollars are available for providing immunization. What percentage of the susceptible population will not receive immunization?
