Fractional reserve banking is the practice where a bank accepts deposits, makes loans or investments, but is required to hold reserves equal to only a fraction of its deposit liabilities.
The expected annual medical expenses of a high-risk person is $3000 per year while that of a low-risk person is $1000 per year.
The expected annual medical expenses of a high-risk person will be calculated as:
= Probability of falling ill × Expenses in case of illness
= 30% × $10000
= 0.3 × $10000
= $3000
The expected annual medical expenses of a low-risk person will be calculated as:
= Probability of falling ill × Expenses in case of illness
= 10% × $10000
= 0.1 × $10000
= $1000
It should be noted that in a situation where the individuals are risk neutral, the low-risk persons will not buy insurance as only the high-risk individuals will be expected to buy<em> insurance.</em>

Answer:
GDP is the value of the total production of final goods and services produced within a country (in this case Ireland), while Gross National Product (GNP), in this specific case, is the value of the total production of final goods and services produced by residents of the Ireland (individuals or businesses).
Since several corporations have international headquarters in Ireland due to special tax regimes, e.g. Apple, Microsoft, Google, Intel, Pfizer, FB, etc., and many of those corporations manage all their world trade (except local trade in the US) through those offices, they are very large and wealthy.
Answer:
D) mixed costs should be separated into their variable and fixed components
Explanation:
A mixed cost is a cost that contains both a fixed cost component and a variable cost component. It is important to understand the mix of these elements of a cost, so that one can predict how costs will change with different levels of activity. Typically, a portion of a mixed cost may be present in the absence of all activity, in addition to which the cost may also increase as activity levels increase. As the level of usage of a mixed cost item increases, the fixed component of the cost will not change, while the variable cost component will increase. The formula for this relationship is
Answer:
portfolio's standard deviation = 6.18%
Explanation:
we must first determine the expected returns for each stock:
stock A = (0.15 x 31%) + (0.6 x 16%) + (0.2 x -3%) + (0.05 x -11%) = 13.1%
stock B = (0.15 x 41%) + (0.6 x 12%) + (0.2 x -6%) + (0.05 x -16%) = 11.35%
stock C = (0.15 x 21%) + (0.6 x 10%) + (0.2 x -4%) + (0.05 x -8%) = 7.95%
then we must determine the variance of each stock's return:
stock A = {[0.15 x (31 - 13.1)²] + [0.6 x (16 - 13.1)²] + [0.2 x (-3- 13.1)²] + [0.05 x (-11 - 13.1)²]} / 4 = (48.0615 + 5.046 + 51.842 + 29.0405) / 4 = 33.4975
stock B = {[0.15 x (41 - 11.35)²] + [0.6 x (12 - 11.35)²] + [0.2 x (-6- 11.35)²] + [0.05 x (-16 - 11.35)²]} / 4 = (131.868375 + 0.2535 + 60.2045 + 37.401125) / 4 = 57.4219
stock C = {[0.15 x (21 - 7.95)²] + [0.6 x (10 - 7.95)²] + [0.2 x (-4- 7.95)²] + [0.05 x (-8 - 7.95)²]} / 4 = (25.545375 + 2.5215 + 28.5605 + 12.720125) / 4 = 17.3369
portfolio's variance = (0.3 x 33.4975) + (0.4 x 57.4219) + (0.3 x 17.3369) = 38.21908
portfolio's standard deviation = √38.21908 = 6.18%
