A round plate has a radius of 8.25 inches. What is the circumference of the plate?

Answers

Answer: The circumference of the plate = 51.86 inches.

Step-by-step explanation:

Given : The radius of a round plate = 8.25 inches

Formula: circumference of a circle = [tex]2\pi r[/tex] , where r = radius of circle .

Then, the circumference of the plate [tex]=2\times\dfrac{22}{7}\times8.25[/tex]   [ [tex]\pi=\dfrac{22}{7}[/tex] ]

[tex]=51.857142857\approx51.86\ \text{inches}[/tex]

Hence, the circumference of the plate = 51.86 inches.

A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a sure rate of 4.2%. The probability distributions of the risky funds are: Expected Return Standard Deviation Stock fund (S) 12 % 33 % Bond fund (B) 5 % 26 % The correlation between the fund returns is .0308. Suppose now that your portfolio must yield an expected return of 11% and be efficient, that is, on the best feasible CAL. a. What is the standard deviation of your portfolio? (Do n

Answers

Answer:

28.63%

Step-by-step explanation:

Given data:

correlation between funds = 0.308

Risk-free rate = 0.042

Expected return rate = 0.11

Calculate the standard deviation of the new portfolio

standard deviation of portfolio = ( weight of risky assets )* (standard deviation of optimal risky portfolio )

weight of risky assets = (expected return - risk-free rate) / ( expected return of optimal portfolio - risk-free rate ) ( calculated using excel spreadsheet)

= 0.9696

Standard deviation of optimal risky portfolio = 29.525489% ( calculated using excel spreadsheet )

hence standard deviation of portfolio that would an expected return of 11%

= 0.9696 * 29.525489%

= 28.63%

A clothes hanger is in the shape on an isosceles triangle. If the hanger is 70° wide what are the base angles?

Answers

Answer:

55°

Step-by-step explanation:

Given parameters:

      Angles in the triangle;

                   70°, X° and X°

The triangle is an isosceles triangle;

  In all triangles, the sum of the interior angles is 180°

  So;

            70° + X° + X° = 180°

            70° + 2X° = 180°

                      2X°  = 180° - 70°

                      2X° = 110°

                        X°  = [tex]\frac{110}{2}[/tex]  = 55°

An eight ft board is cut into two pieces. One piece is 2 ft longer thant he other. How long are the pieces?

Answers

Answer: 6 ft and 2 ft

Step-by-step explanation:

Answer:

6ft and 2ft

Step-by-step explanation:

8ft board ÷ 2 pieces = 4ft each

4ft and 4ft boards. But one of them is longer by 2ft so:

4ft - 2ft = 2ft

4ft + 2 ft = 6ft

So, one piece is 2ft and the other piece is 6ft

The perimeter of a worksheet is 48 inches. The worksheet is 14 inches long. How tall is it?
inches

Answers

Answer: 10 inches

Step-by-step explanation:

1. multiply 14 by 2 to get 28.

2. Subtract 28 from 48 to get 20

3. Divide 20 by 2 to get 10

your answer is 10

Answer: 10 inches

Step-by-step explanation:

a worksheet is usually a rectangle

the formula for the perimeter of a rectangle is 2x + 2y

Lets say that x = the length and y = the height

it already gives you x = 14, so plug everything in to find y

P = 2x + 2y

48 = 2(14) + 2y

48 = 28 + 2y            plug in x = 14 and multiply

20 = 2y                    subtract 28 from both sides to get this

y = 10                       then divide both sides by 2 to get the answer

While on vcacation, kevin and his family visit mount rushmore in south dakota. They watcha movie in the vistor center for 1/2 of an hour. This accounta for 1/4 og the toatl time the spend at mount rushmore. What equation can you use to find the total amount of time t kevin's family spends at mount rushmore

Answers

Answer:

t = 1/2 ÷ 1/4

t = 2 hours

Step-by-step explanation:

Time spent watching movies = 1/2 of an hour

This accounts for 1/4 of the total time thei spend at mount rushmore.

1/2 = 1/4t

Where t = total time they spent at mount rushmore (hours)

1/2 = 1/4t

Determine the equation to find t

t = 1/2 ÷ 1/4

= 1/2 × 4/1

= 4 / 2

= 2

t = 2 hours

writing equations of lines

Answers

Step-by-step explanation:

Equation of straight line is y=mx+c

choose any two points on straight line

for me I choose:(-3,11) and (3,-1)

use these two points to find gradient,m.

m= (-1-11)/(3-(-3))

m= -2

now, y=-2x+c

choose any point on the straight line

I choose point (3,-1)

sub the point into the equation to find c

-1=-2(3)+c

c=5

equation: y=-2x+5

Answers

Answer:

2- Use the same two points from the error analysis question above and show how to calculate the slope correctly. Then, use the correct slope and one of the points to write the equation in point-slope form of the line. Show all work!

Answers

Answer:

Please check explanations for answer

Step-by-step explanation:

Let’s have two points (5,10) and (15,20)

1. Let’s find the slope of these two points

Mathematically, the slope can be calculated using the formula;

m = (y2-y1)/(x1-x2)

So m = (20-10)/(5-15) = 10/-10 = -1

The error here is the formula used in calculating the slope

The formula should be;

m = (y2-y1)/(x2-x1) and not x1-x2

2. To calculate the slope correctly, we have;

m = (y2-y1)/(x2-x1)

So the slope will be;

m = (20-10)/(15-5) = 10/10 = 1

In the point slope form, the equation can be represented as;

y-y1 = m(x-x1)

Let’s use the point (5,10)

y- 10 = 1(x-5)

The above is the point slope form

using one of the points and the correct slope of the line
