Answer:

B. probably live longer than those without such positive attitudes.

Explanation:

An attitude is an entity or principle which defines a person's personality and thoughts. It helps a person building an emotional outlook altogether. Attitude can be both positive and negative. It affects the thought, emotions, and feelings of the person. It depends on the attitude how a person handles a situation. In the case of Meno, it is because of his positive attitude that he will be able to live longer and happier than other people.

Arbor Systems and Gencore stocks both have a volatility of 33%. Compute the volatility of a portfolio with 50% invested in each
fiasKO [112]

Answer:

<h3>In case of b, c, d ,e volatility is less than that of original stock</h3>

Explanation:

The formula to compute the volatility of a portfolio

=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}

Here,

The standard deviation of the first stock is σ₁

The standard deviation of the second stock is σ₂

The weight of the first stock W₁

The weight of the second stock W₂

The correlation between the stock c

a) If the correlation between the stock is +1

=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}

=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times1} \\\\=0.33

Hence, the volatility of the portfolio is 0.33 0r 33%

b) If the correlation between the stock is 0.50

=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}

=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times0.5} \\\\=0.29

Hence, the volatility of the portfolio is 0.29 0r 29%

c) If the correlation between the stock is 0.00

=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}

=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times0.0} \\\\=0.23

Hence, the volatility of the portfolio is 0.23 0r 23%

d) If the correlation between the stock is -0.50

=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}

=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times-0.5} \\\\=0.17

Hence, the volatility of the portfolio is 0.17 or 17%

e) If the correlation between the stock is -1

=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}

=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times-1} \\\\=0

Hence, the volatility of the portfolio is 0

The correct option is C ,$15,300

Explanation:

GDP is a short form of Gross Domestic Product which is an indicator of total goods produced in an economy in a period of one year.

Using the expenditure method,GDP van be computed using the below formula:

GDP=C+I+G+(X-M)

C is the consumption in the economy which is $9000

I is the level of investment at $3,000

G is the government expenditure of $3,500

X is the export of $2,500

M is the import of $2,700

GDP=$9000+$3000+$3500+($2500-$2700)

GDP=$15,300

Hence the GDP is $15,300
