There is a sample selection of 2 items. The probability that one of the item among the selected sample of two items is found defective is 0.2 (2 items sample *10%)

A stock had returns of 12 percent, 16 percent, 10 percent, 19 percent, 15 percent, and -6 percent over the last six years. What
OleMash [197]

Answer:

10.68%

Explanation:

Data provided in the question:

Returns on stock : 12%, 16%, 10%, 19%, 15%, -6%

Now,

Geometric average return on the stock is calculated as:

Geometric average return = ({(1 + r_1)\times(1 + r_2).......\times(1 + r_n)})^\frac{1}{n}- 1

Thus,

For the given returns on stock

Geometric average return

=[ (1 + 0.12)\times(1 + 0.16)\times(1 + 0.10)\times(1 + 0.19)\times(1 + 0.15)\times(1 + (- 0.06)) ]^{\frac{1}{6}}-1

= [ 1.12\times1.16\times1.10\times1.19\times1.15\times0.94 ]^{\frac{1}{6}}-1

=  [1.8384056768]^{\frac{1}{6}}-1

= 1.1068 - 1

= 0.1068

or

= 0.1068 × 100%

= 10.68%

Pachacha [2.7K]

Answer:

(a) 5

(b) $150 million

(c) 45 million

Explanation:

(a) Multiplier = 1 ÷ (1 - MPC )

                     = 1 ÷ (1 - 0.8 )

                     = 1 ÷ 0.2

                     = 5 ⇒ the value of the simple multiplier is 5.

b) If the autonomous expenditure is increased by $30 million then the total output will increase by:

= $30 million × 5

= $150 million

c) If the Marginal propensity to import is 0.3 then the import will increase by:

= 150 × 0.3

= 45 million
