Charlie’s portfolio has an expected annual return at 10%, with an annual standard deviation at 12%. Assume his investment return
Deffense [45]

Answer:

There is a 34.13% probability that the actual return will be between the mean and one standard deviation above the mean.

Step-by-step explanation:

This is problem is solving using the Z-score table.

The Z-score of a measure measures how many standard deviations above/below the mean is a measure. Each Z-score has a pvalue, that represents the percentile of a measure.

What is the probability that the actual return will be between the mean and one standard deviation above the mean?

One measure above the mean is Z = 1

The mean is Z = 0

This means that this probability is the pvalue of Z = 1 subtracted by the pvalue of Z = 0.

Z = 1 has a pvalue of 0.8413.

Z = 0 has a pvalue of 0.50.

This means that there is a 0.8413-0.50 = 0.3413 = 34.13% probability that the actual return will be between the mean and one standard deviation above the mean.

Please Help Asap. Very Hard.
Genrish500 [490]

According to the plot, when t=0,

y_1(0)=a_1\sin0=0

y_2(0)=a_2\cos0=a_2

a_1 and a_2 are the amplitudes of the waves y_1 and y_2, respectively. From the plot it's clear that both a_1 and a_2 are positive, but the maximum value of y_2 is evidently smaller than the maximum value of y_1. So 0, making the answer B.
