Answer:

a) 7% or 0.07

b) 42% or 0.42

Explanation:

Let's begin by listing out the given information:

Population = 902,

Probability distribution

Strongly support = 0.16 or 16%,

Somewhat support = 0.26 or 26%,

Mixed feelings = ?,

Somewhat oppose = 0.14 or 14%,

Strongly oppose = 0.36 or 36%

Don't know = 0.01 or 1%

a) The summation of every probability of an event (survey) is 100% ⇒ Pr (survey) = 100%

Pr (survey) = Pr [strongly support + somewhat support + mixed feelings + somewhat oppose + strongly oppose + don't know]

100 = 16 + 26 + x + 14 + 36 + 1

To obtain the probability of the 'Mixed feelings' populace, we subtract the summation of all other probabilities from 1 or 100%

x = 100 - (16 + 26 + 14 +36 + 1) = 100 - 93

x = 7% or 0.07

∴ the probability of the 'Mixed feelings' populace is 7% or 0.07

b) Probability of a random adult supporting is given by the summation of the probabilities of the adults who strongly support & those who somewhat support

Pr (support) = Pr (strongly support) + Pr (somewhat support)

Pr (support) = 0.16 + 0.26

Pr (support) = 0.42 or 42%

∴ the probability that a randomly chosen adult supports the casino in Toronto is 42%

4: In 2013, the United States Postal Service charged $0.46 to mail a letter weighing up to 1 oz. and $0.20 per ounce for each ad

Gekata [30.6K]

Answer:

The function that would determine the cost in dollars, c(z), of mailing a letter weighing z ounces is (0.46 + 0.20z)

Explanation:

Weight of the letter = z ounces (z is an integer greater than 1)

cost to mail a letter weighing 1 ounce = $0.46

cost to mail an additional ounce = $0.20

cost to mail z additional ounces = z × $0.20 = $0.20z

Total cost of mailing a letter weighing z ounces = $0.46 + $0.20z

Therefore, cost function, c(z) = 0.46 + 0.2z

Policies based on ABC analysis might include investing __________.A. extra care in forecasting for C items. B. more in supplier

Ilia_Sergeevich [38]

Answer:

Correct option is B

more in supplier development for A items.

Explanation:

In materials management, the ABC analysis is an inventory categorization technique. ABC analysis divides an inventory into three categories—"A items" with very tight control and accurate records, "B items" with less tightly controlled and good records, and "C items" with the simplest controls possible and minimal records.

The ABC analysis provides a mechanism for identifying items that will have a significant impact on overall inventory cost, while also providing a mechanism for identifying different categories of stock that will require different management and controls.

What is the distinction between cross-sectional data and time-series data?

AleksAgata [21]

Answer:

B. Cross-sectional data provides information about economic behavior at an instant in time, while time-series data provides information about how an economic variable behaves over time.

Explanation:

There are two types of data, transverse data and time series data. Cross-sectional data is data that exists at a single point in time. For example, data from an observational survey or sales from a firm. Time series data are data that require intertemporal analysis, such as a country's inflation and GDP data, which should be analyzed for evolution. In other words, time series data are analyzed in a manner dependent on the previous period. Current month's inflation depends on the previous month's inflation analysis.

Which of the following statements is correct with respect to inventories? The FIFO method assumes that the costs of the earliest

jeka57 [31]

Answer:

Under FIFO, the ending inventory is based on the latest units purchased.

Explanation:

First in, first out inventory (FIFO) method values cost of goods sold using the purchase price of the "oldest" units in inventory. This means that the cost of the first units sold will be used to determine COGS.

On the other hand, last in, first out (LIFO) method uses the price of the most recently purchased units to determine the cost of goods sold.
