Your team gets hired to add rooftop solar panels to homes in a Tokyo suburb, at the height of the COVID-19 pandemic. To keep your team and the community you are working in safe, your team masks, gets vaccinated, and regularly takes COVID tests. Suppose that 8.5% of local residents are infected with COVID-19. Also, suppose that a COVID-19 antigen test will correctly flag as ‘positive’ 94% of people who actively have COVID-19. However, like all other diagnostic tests, 2% of residents who do not have COVID-19 will also test positive. (2 points) Please calculate the probability that an employee who tests positive for COVID-19 actually has COVID.

(a) A bank offers a savings account with an AER of 10% compounded monthly. If a customer saves 110 euro per month starting now, how much will the customer have in five years' time? (b) A loan for €450,000 is taken out at an APR of 5.2%. How much should annual repayments be if the loan is to be repaid in 15 equal instalments over a 15 year period? Assume the first instalment is paid at the end of the first month. (c) A couple agree to take out a mortgage of €450,000 at a rate of 0.3% per month, in order to purchase a new home. This loan is to be paid back monthly over 25 years with repayments due at the end of each month. The amount of each repayment is €1771. After exactly 11 years of repayments, the couple receive a windfall and decide to repay the remaining balance on the mortgage. Write down a series including the first and last two terms) which shows the total of the present values of all the remaining 14 years of the mortgage (after the last monthly repayment at the end of year 11). Hence find how much the couple will need to repay in order to clear their mortgage entirely. Give your answer correct to the nearest cent

Complete the following design to meet the following requirements: +Vcc C4 R5 R1 C1 out Q1 C3 in R2 R3 R4 C2 Vcc = 12 volts, C1, C2, C3, and C4 are 1000 uF, Q1 is a 2N3904 The output load (not shown) is a 600 ohm resistance connected between the point labeled out and ground. The input signal is from a source with 10 mVpp amplitude at 1000 Hz and the series resistance for this source is 600 ohms (due to the internal source resistance, the voltage appearing at the point labeled in will be less than 10 mVpp). Perfect impedance matching for the input is not required, but output impedance should be closely matched for optimal performance. The output signal measured across the 600 ohm load resistance must be between 200 and 250 mVpp and the sine wave must be clean with no clipping nor obvious distortion.
