The correct conclusion we can draw from the circle graph is an option (D) "Together, Walk and Streetcar are the preferred transportation for 165 residents."
As per the information provided, it is given that:
Bicycle is the preferred transportation for 8% of 300 residents, which is 0.08 x 300 = 24 residents.
Therefore, option (B) "Bicycle is the preferred transportation for 48 residents" is not correct, as it represents twice the actual number.
Option (A) "Bus is the preferred transportation for 25 residents" is not supported by the information in the graph, as the bus section represents 10% of the graph, but we don't know the actual number of residents who prefer the bus.
Option (C) "Together, Streetcar and Cable Car are the preferred transportation for 42 residents" is not correct, as the cable car section alone represents 27% of the graph, which is more than 42 residents.
Option (D) "Together, Walk and Streetcar are the preferred transportation for 165 residents" is supported by the information in the graph, as the walk section represents 40% of the graph, which is 0.4 x 300 = 120 residents, and the streetcar section represents 15% of the graph, which is 0.15 x 300 = 45 residents.
Therefore, the total number of residents who prefer walking or streetcar is 120 + 45 = 165.

The proportion of all students that prefer to use a metal pen would be 40 %.
The bookstore should not believe that the results represent the preferences accurately as the different is significant.
How to find the less variable class?The least amount of time was spent on homework by students in Class B, as seen by the fact that some of them only put in 10, 15, and 20 minutes, as opposed to 35 minutes for students in Class A.
Due to their smaller range, Class A also had less variability in the amount of time spent on homework:
Class A range :

in a game, you have a spinner with 10 equal sections, numbered 1 to 10. what is the probability that you will spin the spinner three times and the sum of the numbers will be exactly 15?
If we spin a spinner with 10 equal-sections, then the probability that on spinning the spinner 3 times the sum becomes 15 is 0.011.
To find the probability of spinning the spinner "3-times" and getting a sum of exactly 15, we use a combination of probability and counting principles.
First, we find total number of possible outcomes when spinning the spinner 3-times.
Since there are 10 possible outcomes for each spin,
There are a total of 10 × 10 × 10 = 1000 possible outcomes,
Next, we count the number of ways to get a "sum-15" by listing out all the possible combinations of three numbers that add up to 15.
The Outcomes are : (1, 7, 7), (2, 6, 7), (2, 7, 6), (3, 5, 7), (3, 6, 6), (3, 7, 5), (4, 4, 7), (4, 5, 6), (4, 6, 5), (4, 7, 4), (5, 5, 5).
So there are 11 possible combinations of three numbers that add up to 15.
The probability of getting "sum-of-15" is found by dividing number of favorable outcomes (11) by total number of possible outcomes (1000);
⇒ P(sum of 15) = 11/1000,
Therefore, the required probability is 0.011.

Answer:
7. To find the theoretical probability of rolling a product greater than 12, we need to count the number of outcomes where the product is greater than 12 and divide by the total number of possible outcomes.
From the table, we can see that the outcomes with a product greater than 12 are: (2, 6), (3, 5), (3, 6), (4, 4), (4, 5), (4, 6), (5, 3), (5, 4), (5, 5), (5, 6), (6, 2), (6, 3), (6, 4), (6, 5), and (6, 6). This gives us a total of 15 outcomes with a product greater than 12.
The total number of possible outcomes is 6 x 6 = 36, since there are 6 possible outcomes for each of the two number cubes.
Therefore, the theoretical probability of rolling a product greater than 12 is 15/36, which simplifies to 5/12.
8. To find the approximate number of times Alan would expect to roll a product greater than 10 in 300 rolls, we can multiply the total number of rolls by the probability of rolling a product greater than 10.
From the table, we can see that the outcomes with a product greater than 10 are: (2, 6), (3, 5), (3, 6), (4, 4), (4, 5), (4, 6), (5, 3), (5, 4), (5, 5), (5, 6), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6), (3, 4), (4, 3), (5, 2), (6, 2), (4, 2), (5, 2), and (6, 2). This gives us a total of 21 outcomes with a product greater than 10.
The probability of rolling a product greater than 10 is 21/36, which simplifies to 7/12.
Multiplying the total number of rolls (300) by the probability (7/12), we get:
300 x 7/12 = 175
So Alan would expect to roll a product greater than 10 about 175 times in 300 rolls.

A new credit card holder must decide between two credit cards. The first card offers a current APR of 13.99%. The second card has a current daily periodic interest rate of 0.035%. Which card would be the better choice?
The second card is the better choice because the daily periodic interest on the first card is 0.038%, compared to 0.035% on the second card.
The second card is the better choice because the daily periodic interest on the first card is 0.035%, compared to 0.038% on the second card.
The first card is the better choice because the daily periodic interest on the first card is 0.035%, compared to 0.038% on the second card.
The first card is the better choice because the daily periodic interest on the first card is 0.038%, compared to 0.035% on the second card.
Based on the comparison of daily periodic interest rates, the second card with a 0.035% daily periodic interest rate is a better choice for a new credit card holder than the first card with a 0.03832% daily periodic interest rate.
You decide which credit card is a better choice by comparing their interest rates.
To make a fair comparison, let's first convert the Annual Percentage Rate (APR) of the first card into a daily periodic interest rate. The APR of the first card is 13.99%. To find the daily periodic interest rate, we divide the APR by 365 (the number of days in a year):
13.99% / 365 = 0.03832%
Now we can compare the daily periodic interest rates of both cards. The first card has a daily periodic interest rate of 0.03832%, and the second card has a daily periodic interest rate of 0.035%.
Since the daily periodic interest rate of the second card (0.035%) is lower than the first card (0.03832%), the second card would be the better choice for a new credit card holder. A lower daily periodic interest rate means that the cardholder will be charged less interest on their outstanding balance, which can save them money over time. Hence, The correct option is The second card is the better choice because the daily periodic interest on the first card is 0.035%, compared to 0.038% on the second card.

Jessica pours herself a cup of boiling water, at 100°C, to make tea. After 312minutes, the temperature of her tea has decreased to 58°C. What was the average change in temperature each minute?
The required average change in temperature each minute is a decrease of 0.13°C.
What is average?The average of the values is the ratio of the total sum of values to the number of values.
We can use the formula:
average change = (final temperature - initial temperature) / time
Here, the initial temperature is 100°C, the final temperature is 58°C, and the time is 312 minutes.
So,
average change = (58 - 100) / 312
average change = -0.1346...

average change = -0.13°C per minute.
So, the average change in temperature each minute is a decrease of 0.13°C.

Using the binomial theorem, we get the value of n to be 1.
The given expression can be simplified by factoring out (1 + x)² from each term, which gives
(1 + x)²[1 + (1 + x) + (1 + x)² + ... + (1 + x)⁴⁷ + (1 + x)⁴⁸]
We can then use the formula for the sum of a geometric series to simplify the expression inside the brackets
1 + (1 + x) + (1 + x)² + ... + (1 + x)⁴⁷ + (1 + x)⁴⁸ = (1 - (1 + x)⁴⁹)/(1 - (1 + x))
= ((1 - (1 + x)⁴⁹)/x)(1/x - 1)
Now, we can use the binomial theorem to expand (1 + x)⁴⁹ and simplify the resulting expression
(1 + x)⁴⁹ = ⁴⁹C₀ + ⁴⁹C₁x + ⁴⁹C₂x² + ... + ⁴⁹C₄₈x⁴⁸ + ⁴⁹C₄₉x⁴⁹
The coefficient of x² is ⁴⁹C₂ + ⁴⁹C₃, which simplifies to (3n + 1)⁵¹C₃. Therefore, we have
⁴⁹C₂ + ⁴⁹C₃ = (3n + 1)⁵¹C₃
We can solve for n by using the formula for binomial coefficients
ⁿCᵣ = n!/(r!(n-r)!)
Substituting this into the above equation and simplifying, we get
(49 × 48)/(2 × 1) + (49 × 48 × 47)/(3 × 2 × 1) = (3n + 1) × (3n) × (3n - 1) × ... × (3n - 50)
Simplifying the left-hand side and dividing both sides by (3n + 1), we get
(49 × 16) + (49 × 24 × 47)/(3 × 2) = (3n) × (3n - 1) × ... × (3n - 50)
784 + 2,352 = (3n) × (3n - 1) × ... × (3n - 50)
3,136 = (3n) × (3n - 1) × ... × (3n - 50)
Since 3n is a factor of the right-hand side, we can write
3n × k = 3,136
where k is a product of the remaining factors on the right-hand side. Since n is the smallest positive integer that satisfies this equation, we can start by letting n = 1 and finding the smallest factor k that is divisible by 3. We find that k = 16 × 31 × 32 × ... × 99. Therefore, the value of n is 1

The product of the two expressions ZW, is 81( cos π²/132 + sinπ²/132 + i(cosπ/11sinπ/12 + sin π/11cos π/12).
The division of the expressions Z/W, is [ (cos π²/132 - sin π²/132) + i (sin π/11 cosπ/12 - sin π/12 cosπ/11) ] / (cos² π/12 - sin² π/12).
What is the simplification of the expression?The given expression is simplified as follows;
Z = 9(cos π/11 + i sin π/11)
W = 9(cos π/12 + i sin π/12)
The product of the two expressions is calculated as follows;
ZW = 9(cos π/11 + i sin π/11) x 9(cos π/12 + i sin π/12)
ZW = 81(cos π²/132 + i cosπ/11 sinπ/12 + i sin π/11 cos π/12 + sin π²/132)
ZW = 81( cos π²/132 + sinπ²/132 + i(cosπ/11sinπ/12 + sin π/11cos π/12)
The division of the expressions is calculated as follows;
Z/W = 9(cos π/11 + i sin π/11) / 9(cos π/12 + i sin π/12)
Z/W = (cos π/11 + i sin π/11) / (cos π/12 + i sin π/12)
Multiply the denominator and numerator with conjugate of (cos π/12 + i sin π/12) = cos π/12 - i sin π/12
Z/W = (cos π/11 + i sin π/11)/(cos π/12 + i sin π/12) x (cos π/12 - i sin π/12)/(cos π/12 - i sin π/12)

Simplify.
(m + 13) - (p + 25)
The expression (m + 13) - (p + 25) after subtraction is simplified to m - p - 12.
The expression (m + 13) - (p + 25) can be simplified by subtracting each term inside the second set of parentheses by -1, which gives
(m + 13) + (-p - 25)
Then, we can group the like terms together
(m - p) + (13 - 25)
Simplifying further, we get
(m - p) - 12
Therefore, (m + 13) - (p + 25) simplifies to m - p - 12, which means that the difference between the sum of m and 13 and the sum of p and 25 is equal to m minus p minus 12.

Use the 30-60-90 Triangle Theorem to find the length of the hypotenuse. Include correct units.
Show all your work.
The length of the hypotenuse is given as follows:
c = 18.
What is the Pythagorean Theorem?The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
The theorem is expressed as follows:
c² = a² + b².
In which:
c is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.The sides for this problem are given as follows:
[tex]a = 9, b = 9\sqrt{3}[/tex]
Then the hypotenuse is given as follows:
[tex]c^2 = 9^2 + (9\sqrt{3})^2[/tex]
c² = 324
c = 18.
