krok68 [10]4 years ago
3 0

Answer:

1. 32

2. 24

3. \frac{1}{12}

4. \frac{1}{8}

5. 15

6. \frac{1}{15}

Step-by-step explanation:

1. 4÷ \frac{1}{8} = 4*8=32

2. 6÷\frac{1}{4} = 6*4=24

3. \frac{1}{3}÷4=\frac{1}{3}*\frac{1}{4} =\frac{1}{12}

4. \frac{1}{2}÷4=\frac{1}{2} *\frac{1}{4} =\frac{1}{8}

5. 5÷\frac{1}{3} =5*3=15

6. \frac{1}3}÷5=\frac{1}{3} *\frac{1}{5} = \frac{1}{15}

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.

GEOMETRY find the angle of PRQ NO LINKS!!
anzhelika [568]

Answer:

55

Step-by-step explanation:

Remark

This is a really good question to know the answer to. <PRQ = 1/2 POQ (the central angle. )

The central angle for this question is 110o. So any angle that has its vertex on the circumference is 1/2 110 = 55. The central angle and the angle on the circumference must be related as they are as this question is. (Both are on the same side of PQ which is not drawn but you can draw it).

The midpoint of ab is M (-6,1 ). if the coordinates of A are (-7,-3 ),what are the coordinates of B
Scrat [10]

Answer:

B(-5,5).

Step-by-step explanation:

It is given that midpoint of AB is M (-6,1).  

Coordinates of A are (-7,-3 ).

We need to find the coordinates of point B.

Let coordinates of point B are (a,b).

Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

Midpoint of AB is

Midpoint=\left(\dfrac{-7+a}{2},\dfrac{-3+b}{2}\right)

(-6,1)=\left(\dfrac{-7+a}{2},\dfrac{-3+b}{2}\right)

On comparing both sides, we get

\dfrac{-7+a}{2}=-6

-7+a=-12

a=-12+7

a=-5

\dfrac{-3+b}{2}=1

-3+b=2

b=2+3

b=5

Therefore, the coordinates of B are (-5,5).
