Rashid [163]

Step-by-step explanation:

<h3>The first dinner</h3>

Combinations of 3 out of 12 items

  • 12C3 = 12!/(12-3)!3! = 12!/9!3! = 12*11*10/2*3 = 220
<h3>The second dinner</h3>

Combinations 3 out of remaining 9 items

  • 9C3 = 9!/(9 - 3)!3! = 9!/6!3! = 9*8*7/2*3 = 84
<h3>The third dinner</h3>

Combinations of 3 out of remaining 6 items

  • 6C3 = 6!/(6 - 3)!3! = 6!/3!3! = 6*5*4/2*3 = 20
<h3>The fourth dinner</h3>

Combinations of 3 out of 3 remaining items

Based on current dividend yields and expected capital gains, the expected rates of return on portfolios a and b are 11% and 14%,
Korvikt [17]

Answer:

∝ for portfolio A = E(rA) - Required return predicted by CAPM

                           = 0.11 - [0.06 + 0.8 × (0.12 - 0.06)]

                           = 0.11 - [0.06 + 0.048]

                           = 0.11 - 0.108

                           = -0.002      ≈ -0.2%  to 1 decimal place

∝ for portfolio B = E(rB) - Required return predicted by CAPM

                           = 0.14 - [0.06 + 1.5 × (0.12 - 0.06)]

                           = 0.14 - [0.06 + 0.09]

                           = 0.14 - 0.15

                           = -0.01         ≈ -1.0% to 1 decimal place

Samantha purchased dinner at a restaurant and spent $38 on food and beverages. Her sales tax was 7%. How much will Samantha pay
Rama09 [41]

Given:

Samantha purchased dinner at a restaurant and spent $38 on food and beverages.

Rate of sales tax = 7%

To find:

How much will Samantha pay for sales tax in dollars and cents?

Solution:

Amount spent on food and beverages = $38

Rate of sales tax = 7%

Sales tax = 7% of $38

\text{Sales tax}=\dfrac{7}{100}\times 38

\text{Sales tax}=\dfrac{266}{100}

\text{Sales tax}=2.66

Therefore, the sales tax is $2.66.
