An investment counselor calls with a hot stock tip. He believes that if the economy remains strong, the investment will result i

Dovator [93]

Answer: expected profit = 18,000 dollars

Step-by-step explanation:

expected value formulae = x * p(x)

x= data value, p(x) = probability of data value

When the economy is strong

profit to be made = 60,000 dollars

probability that economy will be strong = 30/100 = 0.3

expected value = profit * probability at which profit is made

expected value = 0.3 * 60000

expected value = 18,000 dollars

When economy grows at moderate pace

profit to be made = 10,000

probability that economy will be moderate = 60/100 = 0.6

expected value = 0.6 * 10000

expected value = 6,000 dollars

When economy is in recession

loss to be made = -60,000

probability that economy will be in recession = 10/100=0.1

expected value = 0.1 * -60000 = -6000 dollars

negative sign denotes loss.

total investment = 18,000 + 6000 - 6000

total investment = 18,000 dollars

5. Verify the property a× (b-c)= a×b-a×c for each of the following: a= -3\5; b= 5\9; c= -10\3

ohaa [14]

Answer:

We conclude that

$a\times \left(b-c\right)=\:a\times b-a\times c$

$-\frac{7}{3}=-\frac{7}{3}$

L.H.S = R.H.S

Step-by-step explanation:

Given the property expression

$a\times \left(b-c\right)=\:a\times b-a\times c$

Given that:

a = -3/5

b = 5/9

c = -10/3

Determining the LEFT-HAND SIDE

$a\times \left(b-c\right)$

substituting a= -3/5, b= 5/9 and c= -10/3

$a\times \left(b-c\right)\:=\:\:-\frac{3}{5}\times \left(\frac{5}{9}-\left(-\frac{10}{3}\right)\right)\:\:\:\:\:\:\:\:\:\:\:\:$

$=-\frac{3}{5}\times \:\left(\frac{5}{9}+\frac{10}{3}\right)\:\:\:$

$=-\frac{3}{5}\times \frac{35}{9}$

$=-\frac{7}{3}$

Determining the RIGHT-HAND SIDE

$\:a\times \:b-a\times \:c$

substituting a= -3/5, b= 5/9 and c= -10/3

$\:a\times \:b-a\times \:c=ab-ac$

$=-\frac{3}{5}\left(\frac{5}{9}\right)-\left(-\frac{3}{5}\right)\left(-\frac{10}{3}\right)$

$=-\frac{3}{5}\cdot \frac{5}{9}-\frac{3}{5}\cdot \frac{10}{3}$

$=-\frac{15}{45}-\frac{30}{15}$

$=-\frac{1}{3}-2$

$=\frac{-7}{3}$

Apply the fraction rule: $\frac{-a}{b}=-\frac{a}{b}$

$=-\frac{7}{3}$

Therefore, we conclude that

$a\times \left(b-c\right)=\:a\times b-a\times c$

$-\frac{7}{3}=-\frac{7}{3}$

L.H.S = R.H.S
