Find the best measure of variability for the data and determine which player was more consistent.
Player B is the most consistent, with an IQR of 3.5.
Player B is the most consistent, with a range of 10.
Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.
Answers
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

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.

You have a coupon for 30% off your dinner. Your total bill was $50. You also need to pay a 7% sales tax and leave a 22% tip. With the discount, tip + tax included, how much was your dinner?
(It's not 49.50!!! If you get it right, I will give brainliest)
Answers
Answer:
$52.60.
Step-by-step explanation:
After eating at your favorite restaurant, you know that the bill before tax is $52.60 and that the ... You decide to leave a 20% tip for the waiter based on the pre-tax amount. ... How much will the total bill be, including tax and tip? ... To figure out the tip, you need to find 20% of $52.60.
The cost of the dinner is $45.15.
Given
You have a coupon for 30% off your dinner.
Your total bill was $50.
You also need to pay a 7% sales tax and leave a 22% tip.
After a 30% discount the cost of the bill is;
\(= 50 \times \dfrac{30}{100}\\\\= 15\)
The remaining bill is 50 - 15 = $35.
After the discount adds 7% sales tax.
\(=35 \times \dfrac{7}{100}\\\\= 35 \times 0.07\\\\= 2.45\)
The bill after sales tax is = 35 + 2.45 = $37.45.
With the discount, tip + tax included, adding 22% tip is;
\(=35 \times \dfrac{22}{100}\\\\=35 \times 0.22\\\\= 7.7\)
Therefore,
The cost of dinner is
$35 + $2.45 + $7.7 = $45.15
Hence, the cost of the dinner is $45.15.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Explanation: The angles that would make up the top left and right corners of the parallelogram would be (4,0) and (2,0). Because (0, -2) is the bottom left angle, to make this shape a full parallelogram, the y-coordinate of the other angle would have to also be -2, and it would have to be to the right of the origin so the figure does not look sloppy. To add on to this, none of the given x-coordinates are negative, so the fourth point should not have a negative x-coordinate. That would instantly get rid of A, B, and C. Therefore, your answer would be D, or (0, -2).
