By convention, we use a bar graph when the groups on the x-axis (horizontal axis) are represented on a categorical or discrete scale; we use a line graph when the groups on the x-axis are represented on a continuous or numerical scale.

A bar graph is commonly used to display categorical or discrete data, where the groups or categories on the x-axis are distinct and separate from each other.

For example, the x-axis could represent different types of fruits or months of the year. Each category is represented by a separate bar, and the height of each bar corresponds to the frequency, count, or value associated with that category.

On the other hand, a line graph is typically used to represent data on a continuous or numerical scale. The x-axis represents a continuous range of values, such as time, temperature, or distance.

Each data point is plotted as a dot or marker on the graph, and the points are connected by lines. This type of graph is useful for showing trends, patterns, or changes over time or across a continuous range.

The choice of using a bar graph or a line graph depends on the nature of the data and the purpose of the visualization. Categorical data is best represented using a bar graph to emphasize the distinct categories, while numerical or continuous data is better suited for a line graph to visualize trends and relationships.

The values of x and y that make RAPT a parallelogram are;

x = 15 and y = 25

Angle T and angle P are supplementary angles by parallel lines. Thus they sum up to 180 degrees and we have;

3x + 10 + 8x + 5 = 180

11x + 15 = 180

11x = 165

x = 15

T = 55°

P = 125°

Likewise R and T are supplementary angles by parallel lines and so we have;

55 + 5y = 180

5y = 180 -55

5y = 125

y = 25

R = 125°

A must be 55° since the angles add up to 360°.

a. The price of the consol is approximately $133.33.

b. The new price of the consol would be $100. The price of the consol falls by 24.99% and the interest rate rises by 1%.

c. Your holding period return is approximately -49.99%.

a. The price of the consol can be calculated using the formula for the present value of a perpetuity:

Price = Annual Payment / Interest Rate

In this case, the annual payment is $4 and the interest rate is 3%. Substituting these values into the formula:

Price = $4 / 0.03 ≈ $133.33

Therefore, the price of the consol is approximately $133.33.

b. To calculate the new price of the consol if the interest rate rises to 4%, we use the same formula:

New Price = Annual Payment / New Interest Rate

Substituting the values, we get:

New Price = $4 / 0.04 = $100

The percentage change in the price of the consol can be calculated using the formula:

Percentage Change = (New Price - Old Price) / Old Price * 100

Substituting the values, we have:

Percentage Change in Price = ($100 - $133.33) / $133.33 * 100 ≈ -24.99%

The percentage change in the interest rate is simply the difference between the old and new interest rates:

Percentage Change in Interest Rate = (4% - 3%) = 1%

Comparing the two percentages, we can see that the price of the consol falls by approximately 24.99%, while the interest rate rises by 1%.

c. The holding period return can be calculated using the formula:

Holding Period Return = (Ending Value - Initial Value) / Initial Value * 100

The initial value is the purchase price of the consol, which is $133.33, and the ending value is the price of the consol after one year with an interest rate of 6%. Using the formula for the present value of a perpetuity, we can calculate the ending value:

Ending Value = Annual Payment / Interest Rate = $4 / 0.06 = $66.67

Substituting the values into the holding period return formula:

Holding Period Return = ($66.67 - $133.33) / $133.33 * 100 ≈ -49.99%

Therefore, the holding period return is approximately -49.99%.

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

__

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Answer:

4th answer is correct

Step-by-step explanation:

First, let us make x the subject.

\(\sf \frac{x+4}{4} =\frac{y+7}{7}\)

Use cross multiplication.

\(\sf 7(x+4)=4(y+7)\)

Solve the brackets.

\(\sf 7x+28=4y+28\)

Subtract 28 from both sides.

\(\sf 7x=4y+28-28\\\\\sf7x=4y\)

Divide both sides by 7.

\(\sf x=\frac{4y}{7}\)

Now let us find the value of x/4.

To find that, replace x with (4y/7).

Let us find it now.

\(\sf \frac{x}{4} =\frac{\frac{4y}{7} }{4} \\\\\sf \frac{x}{4} =\frac{4y}{7}*\frac{1}{4} \\\\\sf \frac{x}{4} =\frac{4y}{28}\\\\\sf \frac{x}{4} =\frac{y}{7}\)

The Solution.

The Rule is:

Subtract 8 to get the next term, and then add 4 to get the next term, and keep repeating this process.

So, the next three terms are:

The next term will be:

The next term will be:

Hence, the next three terms are 12, 16, and 8.

\( \frac{5}{2x + 1} +\frac{8}{2x + 1}\)

\(= \frac{5 + 8}{2x + 1} \)

\(= \frac{13}{2x + 1} \)

PQ=6,69 units

Step-by-step explanation:

b/Sin32°=c/Sin72°

PQ/Sin32°=12/Sin72°

PQSin72°=12Sin32°

PQ=12Sin32°/Sin72°

PQ=6.69 units

By the concept of the sine rule of triangles the value of PQ is 6.6 units.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sine rule of a triangle states a/sinA = b/sinB = c/sinC.

Given, In a triangle PQR, Q= 72 degrees, R = 32 degrees, and PR= 12.

Let, q is the opposite side to ∠Q and r is the opposite side to ∠R.

Therefore,

q/sinQ = r/sinR.

12/sin72 = r/sin32.

12/0.951 = PQ/0.523.

PQ = (12×0.523)/0.951.

The number of students enrolled at a college is 16,500 and grows by 4% each year. To determine the growth rate of the number of students over a certain period, the formula for compound interest can be used. This information can be useful for college administrators in terms of planning and budgeting.

The compound interest formula can be used to calculate the growth rate of the number of students at the college. The formula is A = P(1 + r/n)^nt,

where A is the final amount,

P is the initial principal,

r is the interest rate,

n is the number of times the interest is compounded per year, and

t is the number of years.

In this case, P is 16,500, r is 4%, n is 1 (since the interest is compounded annually), and t is the number of years. For example, if we want to find the number of students after 5 years, the formula would be A = 16,500(1 + 0.04/1)^(1*5) = 20,221.

This means that the number of students will have grown by 3,721 over a period of 5 years.

This information can be useful for college administrators in terms of planning and budgeting. They can use this data to project the number of students that will be enrolled in future years and make decisions about staffing, resources, and facilities accordingly.

For example, if they know that the number of students will be increasing, they may need to hire more faculty and staff, or build new classrooms and dormitories. On the other hand, if the number of students is projected to decrease, they may need to make cuts in certain areas to balance the budget. Overall, understanding the growth rate of the number of students at a college is an important factor in effective planning and decision-making.

The equation of the line having slope = -1 and passing through a point (-3, 5) is y = -x + 2 and graph is given below.

The general equation of a line is y = m × x + c, where m is the slope and c is the y-intercept of the line.

Given slope is equal to -1.

Therefore the equation of the required line is y = (-1) × x + c.

Given that this line passes through the point (-3, 5).

Therefore we have 5 = (-1) × (-3) + c

⇒ 5 = 3 + c

⇒ 5 - 3 = c

⇒ 2 = c

⇒ c = 2

Therefore the y-intercept of the required line in cartesian coordinate form is (0, 2).

Therefore the required equation of the line is y = (-1) × x + 2

To eliminate the y terms when making a linear combination after multiplying the first equation by 2, you should multiply the second equation by 3.

After completing the multiplication and adding the equations, the result is a new equation that allows us to solve for the prices per pound of apples and bananas.

First equation multiplied by 2:

10x + 6y = 17

Second equation multiplied by 3:

9x + 6y = 15.75

Adding the equations:

(10x + 6y) + (9x + 6y) = 17 + 15.75

19x + 12y = 32.75

The resulting equation is 19x + 12y = 32.75. Now, we can solve this equation to find the price per pound of apples (x) and the price per pound of bananas (y).

Given the system of equations: 5x + 3y = 8.5 (Equation 1)

3x + 2y = 5.25 (Equation 2)

To eliminate the y terms when making a linear combination after multiplying the first equation by 2, we need to multiply the second equation by 3. The resulting equations are:

2(5x + 3y) = 2(8.5)

3(3x + 2y) = 3(5.25)

10x + 6y = 17 (Equation 1 multiplied by 2)

9x + 6y = 15.75 (Equation 2 multiplied by 3)

Adding these equations together:

(10x + 6y) + (9x + 6y) = 17 + 15.75

19x + 12y = 32.75

The resulting equation is 19x + 12y = 32.75. This equation allows us to solve for the prices per pound of apples (x) and bananas (y). To find the individual prices, further algebraic steps or substitution methods can be used.

Answer: 55%

Step-by-step explanation:

The question says that Toronto FC lost 12 of 40 games and drew in 15% of the total games they played. To find the percentage of the games they won, you need to subtract the percentage of games they lost and the percentage of games they drew from 1 since all possibilities add up to 1.

% of games won = 1 - (% of games lost + % of games drawn)

First, Toronto FC lost 12 of 40 games. This means that they lost 12/40 of all games, and this can be simplified to be

3/10

Which is 0.3, or 30%.

Now the questions said that Toronto FC drew in 15% of all games, which means that using the equation from earlier, we can find the percentage of games won.

% of games won = 1 - (30%+15%)

= 1-0.45

= 0.55

Therefore, Toronto FC won in 55% of their games.
