Alex and Fatima both randomly guess all of the answers on a four-question true/false quiz. Because their guesses are random, each question has an equal chance of being correct or incorrect. After the quiz, they try to
predict their grades.

Alex thinks that the probability of getting correct answers on the first three questions is equal to the probability
of getting exactly three questions correct overall. Fatima disagrees. She thinks that the probability of getting
three questions correct overall is greater.

The sample space of possible outcomes is listed below. C represents a correct answer, and I represents an
incorrect answer.
Who is correct. Alex or Fatima?

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
