t ii 9. (a) describe and explain the difference between the mean, median, and mode. (b) make up an example (not in the book or in your lectures) in which the median would be the preferred measure of central tendency.
Answers
a) Mean, median, and mode are measures of central tendency that summarize a set of data by providing a single value that represents the middle or typical data value in a dataset.
Mean: The mean is calculated by adding up all the values in a dataset and dividing by the number of values in the set. The mean is sensitive to outliers and skewed distributions.
Median: The median is the middle value in a dataset when the values are arranged in order. If the dataset has an odd number of values, the median is the middle value. If the dataset has an even number of values, the median is the average of the two middle values. The median is not sensitive to outliers and is a good measure of central tendency for skewed distributions.
Mode: The mode is the value that appears most frequently in a dataset. A dataset can have one mode (unimodal), multiple modes (bimodal or multimodal), or no mode (uniform distribution).
b) A good example of a situation in which the median would be the preferred measure of central tendency is income distribution in a country. In this case, the mean might be skewed by a small number of very high-income individuals, while the median would give a better representation of the typical income of the majority of the population.
Measures of central tendencyMeasures of central tendency (mean, median, and mode) belong to the field of statistics and mathematics. They are a basic concept in descriptive statistics, which is the branch of statistics that deals with summarizing, organizing, and presenting data.
In general, measures of central tendency are a useful tool for making sense of and communicating data, and they are widely used in many different fields and applications.

If Eris Orbit. The recently discovered Eris orbits the Sun every 557 years.
Its average distance (semimajor axis) from the sun is: 67.7 AUDifference between the two dwarf planets is 28.2 AUWhat is its average distance (semimajor axis) from the sun?In order to calculate the semimajor axis of Eris, we need to plug 557 years into the equation
a=P^2/3
a= 557^0.66666667
a = 67.6971 astronomical units.
a = 67.7 AU (Rounded)
Since the average distance for Pluto from the Sun is 39.3 AU

3 years and 2 months ago, you borrowed $18500. Since then, your debt has grown to $25388.66. What nominal rate, compounded monthly, are you being charged on your loan?
Express your answer as a percentage to two decimal places, but do not include the % symbol in your answer (i.e. enter the numbers only).
Answers
The nominal rate, compounded monthly, charged on the loan is approximately 1.47%.
Explanation:
To find the nominal rate, compounded monthly, we can use the formula for compound interest:
A = P\((1 + r/n)^{(nt)\)
Where:
A is the final amount (25388.66),
P is the principal amount (18500),
r is the nominal interest rate (unknown),
n is the number of times interest is compounded per year (12 for monthly compounding),
t is the time in years (3 years and 2 months, which is 3.167 years approximately).
Substituting the given values into the formula, we get:
25388.66 = 18500\((1 + r/12)^{(12 \times 3.167)\)
To solve for r, we can rearrange the equation and isolate r. However, the calculations involved in solving this equation are complex. Using numerical methods or a financial calculator, we find that the approximate value of r is 0.0147.
To express this rate as a percentage to two decimal places, we multiply it by 100:
0.0147 x 100 = 1.47
Therefore, the nominal rate, compounded monthly, charged on the loan is approximately 1.47%.

Answers
Then it will take approximately 6.3 hours for the culture to grow to 80,000 bacteria
The given formula for the number of bacteria in a culture after t hours is:y = 5000(3)^tWe are required to find the number of hours it will take the culture to grow to 80,000.
This can be done by setting y equal to 80,000 and then solving for t.5000(3)^t = 80,000
Divide both sides by 5000:3^t = 16Now, we need to solve for t by taking the logarithm of both sides.
However, it is easier to use logarithmic properties to simplify the equation first.3^t = 2^4
Raise both sides to the power of (1/log3):log3(3^t) = log3(2^4)t = 4/log3(2)Using a calculator, log3(2) ≈ 0.631, so:t ≈ 4/0.631 ≈ 6.3.

The student only budgeted $50 a month for her cell phone. She thought, "I wonder how many gigabytes of data I would have for $50 if I go with Option B?" and wrote B(x)=50 .
B(x)=50, x=
What is the answer to her question?
Answers
1. A(1) = 60 B(1) = 35
2. A(7.5) = 60 B(7.5) = 100
3. Data plan A is constantly 60 which means no added fees (good for long usage)
Data plan B constantly charges 10 with 25 as an entrance fee (good for short usage)
4. See attached files and read the text in parentheses at question 3
50 = 10x + 25 || 25 = 10x || x = 2.5
The functions for the total cost per month for data use are linear in each of
the given options.
Correct responses;
1. A(1) = 60, B(1) = 352. A(7.5) = 60, B(7.5) = 1003. The monthly charge for Option A fixed. The monthly charge for Option B includes a fixed monthly fee and $10 per gigabyte used.4. Please find attached the combined graph of Option A and Option B. Option B is more affordable when the (extra) data usage is less than 3.5 gigabyte each month.The amount of gigabyte of data the student would have for $50 is 2.5 gigabytes.Methods by which the above values are derivedThe given parameters are;
Both plans data allowance per month = 2 gigabytes
Monthly cost for each option are;
Option A: A(x) = 60 = Constant
Option B: B(x) = 10·x + 25
Solution:
1. The values of A(1) and B(1) are;
A(1) = 60
B(1) = 10 × 1 + 25 = 35
Therefore;
A(1) = $60
B(1) = $35
2. The values of A(7.5), and B(7.5) are;
A(7.5) = 60
B(7.5) = 10 × 7.5 + 25 = 100
A(7.5) = $60
B(7.5) = $100
3. The description of each data plan are;
Option A
The data plan of option A has a fixed charge of $60Option B
The charges on the data plan on option B consist of a fixed monthly charge of $25, and $10 per gigabyte of data used.4. Please find attached the graph of the functions of Option A and Option B. From the graph, the most affordable plan to use based on the data usage are;
Option B; If the data used a month, x < 3.5 gigabytesOption A; If the data used a month, x > 3.5 gigabytesEither Option A or Option B if the data usage per month is exactly 3.5 gigabytesThe amount the student budgets per month = $50
By using Option B, we have;

John is going to invest $820 and leave it in an account for 19 years. Assuming
the interest is compounded quarterly, what interest rate, to the nearest tenth
of a percent, would be required in order for John to end up with $1,830?
Answers
John would need an interest rate of approximately 7.1% in order to end up with $1,830 after 19 years with quarterly compounding.
How to find the compound interest?
If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
\(a = p(1 + \dfrac{r}{n})^{nt}\)
Where:
A = the final amount of money
P = the principal (initial investment)
r = the interest rate (annual)
n = the number of times interest is compounded per year
t = the number of years
We know that;
P = $820, t = 19 years, A = $1,830, and n = 4 (quarterly compounding).
Let's solve for r:
A = P(1 + r/n)^(nt)
1830 = 820(1 + r/4)^(419)
1830/820 = (1 + r/4)^(419)
2.2317073 = (1 + r/4)^76
(1 + r/4) = (2.2317073)^(1/76)
1 + r/4 = 1.0177369
r/4 = 0.0177369
r = 0.0709476

Enter the answer with at least 3 decimal places.
Answers
Given statement solution is :- It takes approximately 1.122 seconds for the ball to reach its maximum height.
To find the time it takes for the ball to reach its maximum height, we need to determine the vertex of the parabolic function given by the equation h(t) = \(-4.9t^2 + 11t + 7.\)
The vertex of a parabola in the form y = \(ax^2 + bx\) + c is given by the formula t = -b / (2a).
Comparing the equation h(t) = \(-4.9t^2 + 11t + 7\) to the standard form, we have:
a = -4.9
b = 11
Using the formula for the vertex, we can calculate the time it takes to reach the maximum height:
t = -11 / (2 * -4.9)
t = -11 / -9.8
t ≈ 1.122
Therefore, it takes approximately 1.122 seconds for the ball to reach its maximum height.

Write the coordinates of the vertices after a translation 7 units left and 7 units down. S’ = ( , )T’ = ( , )U’ = ( , )V’ = ( , )
Answers
S' = (-4, -10)
T' = (-4, 0)
U' = (3, 0)
V = (3, -10)
Explanation:Given:
quadrilateral STUV
To find:
The coordinates of the vertex when it is translated 7 units to the left and 7 units down
To determine the new coordinates, we wil be apply int theranslation rlule:
\(\begin{gathered} Translation\text{ to the left: }(x.\text{ y\rparen }\rightarrow\text{ \lparen x-a, y\rparen } \\ Translation\text{ to the right: \lparen x, y\rparen }\rightarrow\text{ \lparen x + a, y\rparen} \\ Translat\imaginaryI on\text{ }to\text{ the top: \lparen x, y\rparen }\rightarrow\text{ \lparen x, y + b\rparen} \\ Translation\text{ to down: \lparen x, y\rparen }\rightarrow\text{ \lparen x, y- b\rparen} \end{gathered}\)Initial coordinates of the vertx:
S = (3, -3), T = (3, 7), U = (10, 7) and V = (10, -3)
\(\begin{gathered} Applying\text{ the translation rule:} \\ S^{\prime}\text{ = \lparen3 - 7, -3-7\rparen= \lparen-4, -10\rparen} \\ T^{\prime}\text{ = \lparen3-7, 7-7\rparen = \lparen-4, 0\rparen} \\ U^{\prime}\text{ = \lparen10-7, 7-7\rparen = \lparen3, 0\rparen} \\ V^{\prime}\text{ = \lparen10-7, -3-7\rparen= \lparen3, -10\rparen} \end{gathered}\)S' = (-4, -10)
T' = (-4, 0)
U' = (3, 0)
V = (3, -10)
