<span>When economists attempt to predict the spending patterns of U.S. households, they will typically view the DAILY COST OF LIVING as a primary determining factor that influences the individual consumption choices that each will make.
An economist can predict the spending power of the masses if he/she knows how much energy and monetary value is being spent on a daily basis. This way he/she will know the consumption choices that these consumers are making for themselves.</span>
Answer:
The second gamble has the higher expected value. EV = 4
Explanation:
In betting, expected value can be defined as (Amount won per bet * probability of winning) – (Amount lost per bet * probability of losing)
For the first gamble:
For the second gamble:
This means that Cal is expected to earn $4 for each $20 waged on the second gamble while he is expected to break even in the first gamble.
Therefore, the second gamble has the higher expected value.
Answer:
- <em>As explained below, given that the score of the person is among the 0.03125 fraction of the best applicants, </em><u><em>he can count on getting one of the jobs.</em></u>
<em></em>
Explanation:
The hint is to use <em>Chebyshev’s Theorem.</em>
Chebyshev’s Theorem applies to any data set, even if it is not bell-shaped.
Chebyshev’s Theorem states that at least 1−1/k² of the data lie within k standard deviations of the mean.
For this sample you have:
- mean: 60
- standard deviation: 6
- score: 84
The number of standard deviations that 84 is from the mean is:
- k = (score - mean) / standar deviation
- k = (84 - 60) / 6 = 24 / 6 = 4
Thus, the score of the person is 4 standard deviations above the mean.
How good is that?
Chebyshev’s Theorem states that at least 1−1/k² of the data lie within k standard deviations of the mean. For k = 4, that is:
- 1 - 1/4² = 1 - 1/16 = 0.9375
- That means that half of 1 - 0.9375 are above k = 4: 0.03125
- Then, 1 - 0.03125 are below k = 4: 0.96875
Since there are 70 positions and 1,000 aplicants, 70/1,000 = 0.07. The compnay should select the best 0.07 of the applicants.
Given that the score of the person is among the 0.03125 upper fraction of the applicants, this person can count of geting one of the jobs.
the main reason the industrial revolution first occurred in Britain was that in Britain the price of coal was low relative to labor. Thus, making everyone want to own and make products using the steam engine which ultimately created the first industrial revolution.
The Industrial Revolution, which took place between roughly 1760 and between 1820 and 1840, was the adoption of new manufacturing techniques in Great Britain, continental Europe, and the United States. This transition encompassed the switch from manual to mechanical production methods, the invention of new ways of producing chemicals and the iron, the expansion of steam and water power, the creation of machine tools, and the growth of the mechanized factory system.

Answer:
The correct word for the blank space is: market cannibalization.
Explanation:
Market cannibalization refers to the loss of revenues as a result of the introduction of a new product by the same company. The initial purpose of the firm is to spread its market share but the product introduced is so similar or covers the same need than the previous that it ends up replacing it instead of acquiring more consumers.
Market cannibalization also takes place when franchises of the same firm open stores too close to each other than one of them ends up capturing all consumers which replace the first store operating in the area.
