We are not positive because life is easy. We are positive because life can be hard.​ Explain, What impact does being positive have on our work life?

Under what conditions do floating point numbers represent something other than a number and what do they then represent?

Thirty-four small communities in Connecticut (population near 10,000 each) gave an average of x = 138.5 reported cases of larceny per year. Assume that σ is known to be 41.7 cases per year.

(a) Find a 90% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(b) Find a 95% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(c) Find a 99% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(d) Compare the margins of error for parts (a) through (c). As the confidence levels increase, do the margins of error increase?

As the confidence level increases, the margin of error decreases.

As the confidence level increases, the margin of error remains the same.     

As the confidence level increases, the margin of error increases.

(e) Compare the lengths of the confidence intervals for parts (a) through (c). As the confidence levels increase, do the confidence intervals increase in length?

As the confidence level increases, the confidence interval increases in length.

As the confidence level increases, the confidence interval remains the same length.     

As the confidence level increases, the confidence interval decreases in length.

50 mL of 0.060 M K₂CrO₄ is mixed with 50 mL of 0.080 M AgNO₃. Calculate the following:

a. The solubility of Ag₂CrO₄ (K_sp = 1.9 X 10^-12) in the solution in moles per liter.

b. The concentrations of the following ions Ag⁺, CrO₄^-2, K⁺, and NO₃^-.

2.    (18 pts) (Media selection) The Samulson Co. has a promotional plan for its new product. Advertising alternatives include television, radio, magazine and newspaper. Audience estimates, costs, and maximum media usage are as shown.

Samulson has the promotional budget of $175,000. To ensure a balanced use of advertising media, radio advertisements must not exceed 35% of the total number of advertisements. Television should account for at least 30% of the total number of advertisements. Television and radio together may not exceed twice of the total of magazine and newspaper advertisements. In addition, the company has decided to use at least 20 ads in each media.

              Set up a linear programming model to maximize audience reached.

4. (20 pts) GA Industries manufactures handling equipment used in distribution centers. One product, called a Liftmaster, has three components: a frame with strap, a motor and two supports. The most recent order has been for 4000 Liftmasters for next month. The sales and production departments must work together to determine delivery schedules. Although the processes used in the manufacture of the three components vary, there are three areas where the production manager is concerned about the availability of resources. These three areas, their usage by the three components, and their availability are detailed in the table.

A quick look at the amounts available confirms that GA does not have the resources to fill this contract. A subcontractor, who can make an unlimited number of each of the three components, quotes the prices below.

The subcontractor requires that the minimum purchase of frame is 600. Due to their production capacity onstraint, the subcontractor can only supply up to 2500 motors.

Develop a linear programming model that would tell GA how to fill the order for 4000 Liftmasters at the minimum cost.

Dividends

Keener Company has had 800 shares of 7%, $100 par preferred stock and 44,000 shares of $5 stated value common stock outstanding for the last 3 years. During that period, dividends paid totaled $4,600, $27,700, and $31,800 for each year, respectively.

Required:

Compute the amount of dividends that Keener must have paid to preferred shareholders and common shareholders in each of the 3 years, given the following 3 independent assumptions:
If an amount is zero, enter "0".

3. Preferred stock is fully participating and cumulative.

Exam question 8: Instrumentation amplifier - Input coupling

8.a): What is the purpose of implementation of an input coupling on an instrumentation amplifier to measure the electrophysiological signals?

(Hint: This is the first component of our electronic system; i.e. the component to which the electrodes are connected. This means that it is necessary to consider safety aspects and that it is the part of the instrumentation system that is most sensitive to noise.)

8.b): Draw an example of an AC-coupled instrumentation amplifier and explain the diagram.

(Hint: What does AC coupling mean when translated into filter terminology (high-pass, low-pass, band-pass, etc.))

8.c): Which type of noise can you reduce by an implementation of the things you described in 8.b)?

(Hint: What noise typically occurs in this frequency range? (according to the answer to 8b))
