Answer:

The value of tan 30 degrees is 0.57736.

Step-by-step explanation:

Tan 30 degrees in radical form is = \frac{1}{\sqrt{3} }

We know \sqrt{3} = 1.732

So, tan 30 degrees = \frac{1}{1.732}

= 0.57736

The answer is 0.57736.

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.

F(x) = x2+3x+2 x2+5x+4 Why is there no zero at x = –1?
dmitriy555 [2]
You could rewrite F(x) as

\dfrac{x^2+3x+2}{x^2+5x+4}=\dfrac{(x+1)(x+2)}{(x+1)(x+4)}

and be tempted to cancel out the factors of x+1. But this cancellation is only valid when x\neq-1.

When x=-1, you end up with the indeterminate form \dfrac00, which is why -1 is not a zero.
