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.

Answer:

Step-by-step explanation:

The y-intercept of the line of fit is 70, which means that a student who does not study at all (0 hours) is predicted to earn a grade of 70%. In other words, the line of fit starts at the point (0,70), indicating that even if a student does not study at all, they can still earn a grade of 70% on the test. However, it should be noted that this prediction may not always hold true for all students and situations. The y-intercept provides a useful reference point for interpreting the rest of the data, and helps to establish a baseline for the relationship between study time and test grades.

Answer:

1.32

Step-by-step explanation:

3 gallon = 1

12 quarts = 4

12 quarts =1

$15.84=  1.32

Answer:

$1.32 per quart

Step-by-step explanation:

To find the price per quart, we must divide the price by the number of quarts.

price / quarts

We are told that a 3 gallon container costs $15.84. First, we must find out how many quarts are in 3 gallons.

We know that 1 gallon is equal to 4 quarts.

Let’s set up a proportion.

quarts/ gallons = quarts/ gallons

4 quarts /1 gallon = x quarts/ 3 gallons

4/1= x/3

Multiply both sides by 3

3*4/1= x/3*3

3*4/1=x

3*4=x

12=x

There are 12 quarts in 3 gallons.

Now we know how many quarts are in 3 gallons. We can find the price per quart.

price / quarts

It costs $15.84 for 12 quarts.

$15.84/12 quarts

Divide 15.84 by 12

$1.32 / quart

It costs $1.32 per quart of window cleaner.

Answer:

you can replace the y in the equation with 4 or -4 and the x with 2 or -2.

then make like all equations you want to get a by itself

right now the equation should look like 4= 2a

now you divide 4/2= 2a/2

now the equation looks like this 2=a or a=2

The value of a is 2.

Given that,

Based on the above information, the calculation is as follows:

Here we have to replace the y with 4 or -4 and the x with 2 or -2

So, it should be like

4= 2a

So, a = 2

Step-by-step explanation:

0.5% of w is 12 is what they are asking

0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is

\(12 = 0.005 \times w\)

Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite

\(w = \frac{12}{0.005} = 2400\)

Answer:

0.5% of w is 12 is what they are asking0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part isNow to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite

Answer: p > 6. Plot a open point on 6 and select the arrow on the right.

Step-by-step explanation:

Tiana wants to include more peanut butter than 6 ounces. So we choose p > 6. 6 can’t be an answer since she want’s a stronger peanut butter flavor, not the same so we can’t plot a closed point meaning greater than or equal. We choose the right arrow as Tiana want’s more peanut butter, not less. Also note that you can plot a point on 7, but it has to be a closed point because 7 is an answer so we do greater than or equal to.

Answer:

36 sq ft

Step-by-step explanation:

12 times 3 feet = 36ft squared

Given the following information:

\(\displaystyle\sf n(U) = 50\)

\(\displaystyle\sf n(P) = 28\)

\(\displaystyle\sf n(Q) = 35\)

\(\displaystyle\sf n(P'\cap Q') = x\)

Let's express the requested values in terms of x:

1. \(\displaystyle\sf P'\cap Q\):

Using the principle of complements, we know that \(\displaystyle\sf P'\cap Q = U \setminus (P \cup Q) = U - (P \cup Q)\).

Since the universal set U has 50 elements, and we are given that \(\displaystyle\sf n(P) = 28\) and \(\displaystyle\sf n(Q) = 35\), we can calculate the value of \(\displaystyle\sf n(P \cup Q)\):

\(\displaystyle\sf n(P \cup Q) = n(P) + n(Q) - n(P \cap Q)\).

Since we don't have the value of \(\displaystyle\sf n(P \cap Q)\), we cannot calculate the exact value of \(\displaystyle\sf n(P \cup Q)\). Therefore, we cannot express \(\displaystyle\sf P'\cap Q\) in terms of x.

2. \(\displaystyle\sf P \cap Q\):

Using the same principle of complements, we know that \(\displaystyle\sf P \cap Q = U \setminus (P' \cup Q') = U - (P' \cup Q')\).

Similarly, we cannot calculate the exact value of \(\displaystyle\sf n(P' \cup Q')\) since we don't know \(\displaystyle\sf x\). Thus, we cannot express \(\displaystyle\sf P \cap Q\) in terms of x.

3. \(\displaystyle\sf n(P \cap Q')\):

Using De Morgan's laws, we know that \(\displaystyle\sf n(P \cap Q') = n(P) - n(P \cap Q)\).

Since we are given that \(\displaystyle\sf n(P) = 28\), we need to calculate \(\displaystyle\sf n(P \cap Q)\). Unfortunately, we don't have enough information to find the exact value of \(\displaystyle\sf n(P \cap Q)\) in terms of x. Therefore, we cannot express \(\displaystyle\sf n(P \cap Q')\) in terms of x.

Regarding the greatest and smallest possible values of x, without additional information or constraints, we cannot determine those values. We would need more details or conditions related to the intersection of sets P and Q or other relevant factors to determine the range or limitations of x.

This is a question related to set theory, a branch of mathematics that deals with the properties of well-defined collections of objects1. Here are some formulas that might help you solve the question2:

The complement of a set A is denoted by A’ and it contains all the elements that are not in A.

The union of two sets A and B is denoted by A ∪ B and it contains all the elements that are in either A or B or both.

The intersection of two sets A and B is denoted by A ∩ B and it contains all the elements that are in both A and B.

The difference of two sets A and B is denoted by A - B and it contains all the elements that are in A but not in B.

The cardinality of a set A is denoted by n(A) and it represents the number of elements in A.

Using these formulas, we can express the sets (P’nQ), (PnQ), and n(PnQ’) in terms of x as follows:

(P’nQ) = (P ∪ Q)’ = U - (P ∪ Q) = U - P - Q + P ∩ Q

(PnQ) = P ∩ Q

n(PnQ’) = n(P) + n(Q’) - n(P ∩ Q’) = n(P) + n(U) - n(Q) - n(P ∩ Q)

To find the greatest and smallest possible values of x, we need to use the following formula2:

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

Applying this formula to P and Q, we get:

n(P ∪ Q) = n(P) + n(Q) - n(P ∩ Q)

50 - x = 28 + 35 - n(P ∩ Q)

x + n(P ∩ Q) = 13

Since x and n(P ∩ Q) are both non-negative integers, the greatest possible value of x is 13 when n(P ∩ Q) is 0, and the smallest possible value of x is 0 when n(P ∩ Q) is 13.

I hope this helps you understand the question better.

Step-by-step explanation:

Answer:

x =14

Step-by-step explanation:

Vertical angles are equal.

This means that 3x = 42

Divide each side by 3

3x/3 = 42/3

x =14

Answer: x=46.

Step-by-step explanation:

Vertical angles are opposite of one another. A whole line is 180 degrees. You have to subtract 42 from 180 which gives you 138. Then you divide by 3. Then you get 46.

Answer:

Saints; they have a larger mean value of about 14 points

Step-by-step explanation:

The mean is the best to use here since we are trying to determine the best overall record. Adding up all of the scores for the Saints will get you a total of 210, which then has to be divided by the number of numbers, which is 15. The Saints' mean is larger than the mean for the Cowboys, making your answer "Saints; they have a larger mean value of about 14 points".

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.
