Answer:

9 : 7

Step-by-step explanation:

given the ratio

4.5 : 3 \(\frac{1}{2}\) , that is in decimal form

4.5 : 3.5 ( multiply both parts by 10 to clear the decimal )

= 45 : 35 ( divide both parts by 5 )

= 9 : 7 ← in simplest form

Answer:

9:7

Step-by-step explanation:

Convert all the numbers to either decimal or fraction. The operation becomes simple.

Simplifying after converting to decimal

Convert 3 1/2 to decimal 3 1/2 = 3 + 1/2

1/2 = 0.5

3 + 1/2 = 3 + 0.5 = 3.4

Ratio 4.5:3.5 = 4.5/3.5

Divide by 5 to give
\(\dfrac{4.5 /5 }{3.5/5} = 0.9/0.7\\\\\)

Multiply both numerator and denominator by 10
0.9 x 10 = 9

0.7 x 10 = 7

So the ratio becomes 9/7 = 9:7

Simplifying after converting to fraction

4.5 = 4 + 0.5

0.5 = 1/2

5.5 = 4 + 1/2 = 4 1/2

Convert to mixed fraction:
4 1/2 = (4 x 2 + 1)/2 = 9/2

Convert 3 1/2 to fraction

3 1/2 = (3 x 2 + 1)/2 = 7/2

So 4.5 : 3 1/2 = 9/2 : 7/2

Multiplying by 2 we get the same answer: 9:7

The statement that is not true about qualitative data is: "We can obtain the mean and variance for qualitative data".

The statement "we can calculate relative frequency for qualitative data for each category in the data" is true. Relative frequency is the proportion of each category in the data, and we can calculate it for qualitative data by dividing the frequency of each category by the total number of observations.

The statement "qualitative data cannot be summarized using a frequency table" is false. A frequency table is a common method for summarizing qualitative data. It displays the frequency of each category in a table format, making it easier to compare and analyze the different categories.

The statement "we can obtain the mean and variance for qualitative data" is false. Mean and variance are measures of central tendency and variability that require numerical data. Qualitative data, being non-numerical, cannot be measured using these statistical measures.

The statement "bar charts and pie charts are usually used to describe qualitative data" is true. Bar charts and pie charts are graphical representations that are commonly used to visually display the distribution of qualitative data. These charts can show the relative frequency or proportion of each category in the data.

The correct formula that defines an arithmetic sequence is option d) tn = 5n + 14.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant. In other words, each term can be obtained by adding a fixed value (the common difference) to the previous term.

In option a) tn = 5 + 14, the term does not depend on the value of n and does not exhibit a constant difference between terms. Therefore, it does not represent an arithmetic sequence.

Option b) tn = 5n² + 14 represents a quadratic sequence, where the difference between consecutive terms increases with each term. It does not represent an arithmetic sequence.

Option c) tn = 5n(n+14) represents a sequence with a varying difference, as it depends on the value of n. It does not represent an arithmetic sequence.

Option d) tn = 5n + 14 represents an arithmetic sequence, where each term is obtained by adding a constant value of 5 to the previous term. The common difference between consecutive terms is 5, making it the correct formula for an arithmetic sequence.

Based on the scatter plot, the meaning of the slope in this scenario is that: The slope of the line of best fit is 0.25. Each time the shoe size increases by one, the height increases by 0.25 inches.

In this scenario, the woman's shoe size would be plotted on the x-axis of the scatter plot while her height would be plotted on the y-axis of the scatter plot.

From the Excel sheet, you should right click on a data point on the scatter plot, select format trend line (line of best fit) and then tick the box to display an equation for the line of best fit on the chart.

By critically observing the scatter plot (see attachment) which models the data in the given table, we can reasonably and logically deduce that an equation for the line of best fit is given by:

y = 0.25x + 66.6

In conclusion, the slope of this line is 0.25, which implies that when the shoe size is increased by one (1), the height is increased by 0.25 inches.

Answer:

\(8\).

Step-by-step explanation:

Notice that in equation for the total dollar amount collected (\(12+ 1.75\, n\)), every additional bottle sold at the new price brings in \(1.75\) dollars:

\(\begin{aligned}& 12 + 1.75\, n && \text{$n$ bottles at new price} \\ -\; & 12 + 1.75\, (n+1) && \text{$(n+1)$ bottles at new price} \\ =\; & 1.75\end{aligned}\).

Therefore, the per-bottle price after the \(\$0.25\) price increase would be \(\$1.75\). The per-bottle price before the price increase would be \(\$1.75 - \$0.25 = \$1.50\).

Also notice that when \(n = 0\), the total amount collected was \(t = 12 + 1.75\, n = 12\). In other words, the total amount collected was \(\$12\) before any bottle was sold at the new price.

Thus, the vendor had collected \(\$12\!\) by selling at the initial price of \(\$1.50\) per bottle. The number of bottles sold at that price would be:

\(\begin{aligned}\frac{12}{1.50} = 8\end{aligned}\).

The solutions to the equation \(2/x - 1 = 16/(x^2 + 3x - 4) are x = 2 and x = (-1 ± √17) / 2.\)

To solve the equation \(2/x - 1 = 16/(x^2 + 3x - 4),\) we'll simplify and rearrange the equation to isolate the variable x. Here's the step-by-step solution:

1. Start with the given equation: 2/x - 1 = 16/(x^2 + 3x - 4)

2. Multiply both sides of the equation by x(x^2 + 3x - 4) to eliminate the denominators:

\(2(x^2 + 3x - 4) - x(x^2 + 3x - 4) = 16x\)

3. Simplify the equation:

\(2x^2 + 6x - 8 - x^3 - 3x^2 + 4x - 16x = 16x\)

4. Combine like terms:

  -x^3 - x^2 + 14x - 8 = 16x

5. Move all terms to one side of the equation:

\(-x^3 - x^2 - 2x - 8 = 0\)

6. Rearrange the equation in descending order:

  -x^3 - x^2 - 2x + 8 = 0

7. Try to find a factor of the equation. By trial and error, we find that x = 2 is a root of the equation.

8. Divide the equation by (x - 2):

\(-(x - 2)(x^2 + x - 4) = 0\)

9. Apply the zero product property:

  x - 2 = 0 or x^2 + x - 4 = 0

10. Solve each equation separately:

   x = 2

11. Solve the quadratic equation:

   For x^2 + x - 4 = 0, you can use the quadratic formula or factoring to solve it. The quadratic formula gives:

 \(x = (-1 ± √(1^2 - 4(1)(-4))) / (2(1)) x = (-1 ± √(1 + 16)) / 2 x = (-1 ± √17) / 2\)

Therefore, the solutions to the equation\(2/x - 1 = 16/(x^2 + 3x - 4) are x = 2 and x = (-1 ± √17) / 2.\)

The monthly payment for the car loan is approximately 16,216.38 pesos. The outstanding balance after 2 years is approximately 650,577.85 pesos.

To find the monthly payment for the car loan, we can use the formula for the monthly payment on a loan:

P = (r * PV) / (1 - (1 + r)^(-n))

Where:

P is the monthly payment

r is the monthly interest rate

PV is the loan amount (present value)

n is the total number of payments

In this case, the loan amount PV is 800,000 pesos, the monthly interest rate r is 7% / 12 (since the interest is compounded monthly), and the total number of payments n is 5 years * 12 months/year = 60 months.

Substituting these values into the formula, we have:

P = (0.07/12 * 800,000) / (1 - (1 + 0.07/12)^(-60))

Calculating this expression, we find that P ≈ 16,216.38 pesos.

So, the monthly payment for the car loan is approximately 16,216.38 pesos.

To find the outstanding balance after 2 years, we need to calculate the remaining balance after making monthly payments for 2 years. We can use the formula for the remaining balance on a loan:

Remaining Balance = PV * (1 + r)^n - P * ((1 + r)^n - 1) / r

Where:

PV is the loan amount (present value)

r is the monthly interest rate

n is the number of payments made

Substituting the given values into the formula, we have:

Remaining Balance = 800,000 * (1 + 0.07/12)^24 - 16,216.38 * ((1 + 0.07/12)^24 - 1) / (0.07/12)

Calculating this expression, we find that the outstanding balance after 2 years is approximately 650,577.85 pesos.

So, the outstanding balance after 2 years is approximately 650,577.85 pesos.
