Lenny bought x shares of stock for Sy per share last month. He paid
his broker a flat fee of $20. He sold the stock this month for Sp per
share, and paid his broker a 2% commission. Express Lenny's net
proceeds algebraically.

Answers

Lenny's net proceeds algebraically are found as;[tex]\rm |xy + 20 - \frac{98}{100} |[/tex]

What is the equation?

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

Let the bought share will be $ x, and $y is the price per share

Paid fees to the broker = $ 20

The total amount spent = $(xy+20)

The price at which each share sells = $ A

Broker commission = 2 %

The total amount obtained after selling the shares;

⇒ ax - 2% of ax

⇒ 98 % of ax

Hence, Lenny's net proceeds algebraically are found as;[tex]\rm |xy + 20 - \frac{98}{100} |[/tex]

2. What is the probability of all three kids being boys?
3. What is the chance of only the middle kid being a girl?
4. What is the probability of there being at least two boys?
5. What is the chance of there being at most one girl?

Answers

Answer: Sample space: {BBB, BBG, BGB, BGG, GBB, GBG, GGB, GGG}

1. 8 outcomes in total

2. 1/8 or 0.125

3. 1/2 or 0.5

4. 1/2 or 0.5

5. 3/8 or 0.375

Step-by-step explanation:

1. As shown by the sample space and the tree diagram, there are 8 total possibilities.

2. There is only a 1/8 or 0.125 chance of there being all boys, which is BBB

3. There are 4 outcomes that allow the middle child to be a girl, and 4/8 = 1/2. There will only be a girl middle child with BGB, GGG, BGG, and GGB.

4. We can think of at least as meaning no less than two boys, which includes two to three boys. The only outcomes that have either two or three boys is BBB, BBG, BGB, GBB. 4/8 = 1/2.

5. We can think of at most as meaning no more than one girl. The only outcomes that have only one girl are BBG, BGB, and GBB, which is 3/8.

Two bikers meet at a park. Biker A needs to stop at the store that is 12 miles east of the park. Biker B heads southeast at a 61° angle at the same time for 24 miles. Once biker A leaves the store he heads southwest at an angle of 89° for 21 miles. Do NOT use the law of cosines, use your knowledge from the content of this course.

a. Use your knowledge of triangles to figure out if the two bikers will be able to meet up if each biker travels the distance given.
b. If they do not meet up, how much farther would one of the bikers have to travel to meet the other?
c. What is the measure of the angle between the bikers?

e. Classify the triangle the paths created.
f. How many miles did they travel together?

Answers

The bikers will meet at point N, all the questions have been answered below.

What is a Triangle?

A triangle is a polygon with three sides, angles, and vertices.

The triangle MNO is formed on the basis of the data given in the question

If the triangle satisfies the sine-rule then the biker meets the other biker at point N

According to the sine rule

In a Triangle ABC of side length a,b and c respectively

a/ sin A = b/ sin B = c/sin C

NM/sin NOM =21/ sin 61°

NM/sin NOM = 24.01

NO/sin OMN =24/sin 89°

NO/sin OMN = 24.003

∠ONM = ( 180-61-89) = 30°

OM / sin ONM = 12/ sin 30 = 24

The ratio of the side and angles of the triangle are almost equal, therefore they satisfy the sine rule

and so, the bikers will meet at point N.

As they are meeting the distance between them will be zero.

The measure of the angle between the bikers is as calculated above = 30°.

The largest angle is opposite to the longer path.

The triangle formed is an acute angle triangle.

Total miles they travelled = 24+12+21 = 57 miles.

Answers

Answer:

Step-by-step explanation:

x = Edith's age = 20 years

y = Ronald's age

x = 20 = y/4

y = 20×4 = 80 years

in z years we have

(x + z) = (y + z)/3

(20 + z) = (80 + z)/3

3(20 + z) = 80 + z

60 + 3z = 80 + z

60 + 2z = 80

2z = 20

z = 10

in 10 years Edith's age will be 1/3 of Ronald's age.

then Edith will be 30, and Ronald will be 90.

30 = 90/3

Whih number produces a rational number multiplied by 0.5

Answers

The question is incomplete. Please find the full content below.

Which number produces a rational number multiplied by 0.5

(C) 2.22 produces a rational number multiplied by 0.5.

If a number can be expressed by p/q form where p and q are whole numbers and q does not equal to 0, is called a Rational number.

If a number cannot be expressed as above then that number is called Irrational Number.

In simple term, we can say that the never-ending decimal numbers and square roots of non perfect square numbers are Irrational Numbers.

Product of two rational numbers is always a rational and the product of one rational and one irrational is always an irrational number.

Here given that the number is 0.5 which is clearly a rational number.

In order to get a rational number, we have to multiply another rational number with that.

In the given choices,

[tex]\pi=3.14......[/tex]

is a never-ending decimal number that is irrational.

7 is not a perfect square so

[tex]\sqrt{7}[/tex]

is an irrational number.

2.020020002.... is also a never-ending decimal number hence it is irrational.

Only 2.22 is rational here.

So multiplication of 2.22 and 0.5 produces a rational number since the product of two rational numbers is always a rational number.

Hence option (C) is correct.

This table represents a linear function. x y 0 5 5 15 This graph represents another function.The greater unit rate of the two functions is . The greater y-intercept of the two functions is

Answers

The greater unit rate (slope) of the two functions is 2 (of the first function).

The greater y-intercept of the two functions is 6 (of the second function).

The unit rate (slope) of a linear function is the rise (or fall) in the independent variable for a unit change in the dependent variable.

When the linear function goes through the points (x₁, y₁) and (x₂, y₂), then the unit rate (slope) can be calculated as (y₂ - y₁)/(x₂ - x₁).

The first function goes through the points (0, 5) and (5, 15).

Thus unit rate (slope) of the first function = (15 - 5)/(5 - 0) = 2.

The second function goes through the points (0, 6) and (-4, 0).

Thus unit rate (slope) of the second function = (6 - 0)/(0 - (-4)) = 1.5.

Therefore, the greater unit rate (slope) of the two functions is 2 (of the first function).

The y-intercept of a linear function is the y-coordinate of the point at which the graph of the function intersects the y-axis. It is also shown as the point (0, b).

The y-intercept of the first function is 5, as it passes through the point (0, 5).

The y-intercept of the second function is 6, as it passes through the point (0, 6).

Therefore, the greater y-intercept of the two functions is 6 (of the second function).

answer in % without the symbol

Answers

The nominal rate on a three year Treasury Bond, which is the risk-free rate plus the inflation premium, is 6%.

What are nominal rates?

The nominal interest rate (also known as the money interest rate) is the percentage of interest that the borrower pays to the lender for a loan.

The nominal interest rate includes the real rate and the inflation premium.

Data and Calculations:

Risk-free rate = 2%

Inflation premium = 4.0%

Maturity risk premium = 3.7%

Liquidity premium = 3%

Default risk premium = 3.5%

Nominal rate for Treasury Bond = Risk-free rate plus Inflation premium

= 6% (2% + 4%)

Thus, the nominal rate on a three year Treasury Bond is 6%.

x + 2y = -4
2x + 3y = 1

Answers

Answer:

(14, -9)

Step-by-step explanation:

So you can solve this using substitution. When you're solving a systems of equations, you're looking for when (x, y) is the same for both equations, or in other words where the two linear equations intersect. Because of this we can solve for x or y in one equation and substitute it into the other equation, since the x and y in one equation should equal the x and y in the other equation.

Original equation:

x + 2y = -4

Subtract 2y from both sides

x = -2y - 4

Original equation:

2x + 3y = 1

Substitute -2y -4 as x

2(-2y - 4) + 3y = 1

Distribute the 2

-4y - 8 + 3y = 1

Combine like terms

-y - 8 = 1

Add 8 to both sides

-y = 9

Multiply both sides by -1

y = -9

So now that you know what y is, you can plug it into either equation to solve for x:

x + 2y = -4

Plug in -9 as y

x + 2(-9) = -4

Multiply

x - 18 = -4

Add 18 to both sides

x = 14

So this gives you the solution (14, -9)

Two trains leave a station at the same time. One train is heading south at a rate that is 1.5 times faster than the other train, which is heading north. After 5 hours, the trains are 750 miles apart. At what speed, in mph, are the two trains getting farther away from each other?

Answers

Answer:

150 mph

Step-by-step explanation:

The relationship between time, speed, and distance is ...

speed = distance/time

(750 mi)/(5 h) = 150 mi/h

The trains are separating at a speed of 150 mph.
