Simple exponential smoothing (with α = 0.2) is being used to forecast monthly beer sales at Gordon’s Liquor Store. After observing April’s demand, the predicted demand for May is 4,000 cans of beer. a. At the beginning of May, what is the prediction for July’s beer sales? b. Actual demand during May and June is as follows: May, 4,500 cans of beer; June, 3,500 cans of beer. After observing June’s demand, what is the forecast for July’s demand? c. The demand during May and June averages out to $\frac{4,500+3,500}{2}=4,000$ cans per month. This is the same as the forecast for monthly sales before we observed the May and June data. Yet after observing the May and June demands for beer, our forecast for July demand has decreased from what it was at the end of April. Why?

The price p (dollars per unit) of a particular commodity is increasing at the rate $p^{\prime}(x)=\frac{20 x}{(7-x)^{2}}$ when x hundred units of the commodity are supplied to the market. The manufacturer supplies 200 units (x = 2) when the price is $2 per unit. a. Find the supply function p(x). b. What price corresponds to a supply of 500 units?

Jerry says that if a store has a sale for $35 \%$ off and the sale price of a treadmill is $137$, then he can figure out what the original price was by taking $35 \%$ of $137$ and adding it back onto the $137$. So the original price should be $184.95$. But the answer doesn’t check. Explain what mistake Jerry is making.

There are 5 hotels in a certain town. If 3 people check into hotels in a day, what is the probability that they each check into a different hotel? What assumptions are you making?

Consider a sample comprised of firms that were targets of tender offers during the period $1978-1985.$ Conduct an analysis where the response variable represents the number of bids (Bids) received prior to the takeover of the firm. The explanatory variables include the bid premium (Premium) and firm size (Size in dollar billions). It is generally believed that a high initial bid premium, defined as the percentage excess of the firm's stock price, would deter subsequent bids. Moreover, while tender offers for large firms are likely to receive more media coverage and thereby attract the attention of opportunistic bidders, it also is a wealth constraint to potential bidders. A portion of the data is shown in the accompanying table.

$$\begin{array}{|c|c|c|} \hline \text { Bids } & \text { Premium } & \text { Size } \\ \hline 3 & 1.1905 & 0.7668 \\ \hline 1 & 1.0360 & 0.1625 \\ \hline \vdots & \vdots & \vdots \\ \hline 2 & 1.0329 & 3.4751 \\ \hline \end{array}$$

Justify the inclusion of the quadratic term in the model.

The per unit price p (in dollars) of a popular toy when x units (in thousands) are produced is modeled by the function

$$price=p=12-0.025x$$

The revenue (in thousands of dollars) is the product of the price per unit and the number of units (in thousands) produced. That is,

$$revenue=xp=x(12-0.025x).$$

How many units should be produced if the total revenue is to be $1,000,000?

Grains of fine California beach sand are approximately spheres with an average radius of 50 μm and are made of silicon dioxide, which has a density of 2600 kg/m³. What mass of sand grains would have a total surface area (the total area of all the individual spheres) equal to the surface area of a cube 1.00 m on an edge?

What is the relationship between a polymer and a monomer?

For each situation, write an appropriate differential equation (unlimited, limited, or logistic). Then find its solution and solve the problem. Since the year 2000 the price of a movie ticket has been growing continuously at the rate of about 4% per year. If in 2010 the nationwide average price was $7.85, estimate the price in the year 2018.
