Hope this helped!
-Toshino
The values for a and b are a = 13 and b = 13, and the percent error is 13%.
The correct option is B.
To find the values of a and b in the table, we need to calculate the error and absolute error between the approximate value and the exact value.
Given that Dion predicted selling 87 art prints (approximate value) but actually sold 100 art prints (exact value), we can calculate the error by subtracting the approximate value from the exact value:
Error = Exact value - Approximate value
= 100 - 87 = 13.
The absolute error is the absolute value of the error:
Absolute error = |Error|
= |13|
= 13.
From the given options, the correct values of a and b are: a = 13 and b = 13.
To calculate the ratio, we divide the absolute error by the exact value:
Ratio = Absolute error / Exact value
= 13 / 100.
To find the percent error, we multiply the ratio by 100:
Percent error = Ratio x 100
= (13 / 100) x 100
= 13%.

Answers
Answer: 540 words.
Step-by-step explanation: I'm gonna do '/' for a fraction.
So, what you would do is put 225 over 5. 225/5
Divide 225 and 5 by 5, 5 divided by 5 is 1, and 225 divided by 5 is 45.
Well, 12 x 1 is 12, right? Yes, so then what you do to the bottom you have to do to the top. 45 x 12 is 540.
the answer as a fraction is 540/12 and don't forget to add your labels! 12m and 540w

Decimal answer is 13.5
fraction is 13 1/5
Answer: 66/5 or 13 1/5
Step-by-step explanation: The first step in solving this problem is to create two fractions that can be multiplied together. So the first number will be an improper fraction, but that is what you need to do.
4 and 2/5 should be changed by multiplying the denominator (5) times the whole number (4). We get 20. Now we add the numerator (2). The new numerator is then 22. The denominator does not change. 22/5. The 3 can easily be made into a fraction by putting a whole in the denominator. The result is 3/1. Now you can multiply those two fractions together: numerators (22X3) and denominators (5X1). The result of that is 66/5. If your supposed to make it a mixed number, divide the top number by the bottom number (66/5) = 13 1/5.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.
Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

If the relationships below are given in the form (input, output), which pairing always describes a function? (a person’s age in years, that same person’s height in inches) (a person’s weight in pounds, that same person’s height in inches) (a person’s height in centimeters, that same person’s height in inches) (a person’s telephone number, that same person’s height in inches)
Answers
Answer:
A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:
(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.
(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.
(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.
(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.
So, the pairings that always describe a function are:
(a person’s age in years, that same person’s height in inches)
(a person’s weight in pounds, that same person’s height in inches)
(a person’s height in centimeters, that same person’s height in inches)
These three pairings meet the criteria of a function, where each input corresponds to a unique output.
The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)
How did we arrive at this assertion?A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:
1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).
2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.
3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.
4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).
So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.
