Evaluate the integral. 0∫1 r3 /√16 + r2 dr

Answers

Answer 1

The value of the integral \(\int\limits^1_0 {\frac{r^3}{\sqrt{16+r^2} } } \, dr\) after the evaluation of the integral is 0.0612.

Given an integral:

\(\int\limits^1_0 {\frac{r^3}{\sqrt{16+r^2} } } \, dr\)

It is required to find the value of the integral.

There is a formula to find the integration by parts of definite integrals as:

\(\int(udv)=uv-\int(vdu)\)

Here, let u = r².

Then, du = 2r dr

Then, using the formula:

\(dv=\frac{r}{\sqrt{16+r^2} }\)

Then, \(v=\sqrt{16+r^2}\).

Applying the formula,

\(\int\limits^1_0 {\frac{r^3}{\sqrt{16+r^2} } } \, dr=[r^2\sqrt{16+r^2} ]_0^1-\int\limits^1_02r\sqrt{16+r^2} dr\)

For the second integral, let x = 16 + r².

Then, dx = 2r dr

So, the integral becomes \(\int\sqrt{x} dx\) which is \(\int\sqrt{16+r^2} dr\).

So, the integral is:

\(\int\limits^1_0 {\frac{r^3}{\sqrt{16+r^2} } } \, dr=\sqrt{17} -[\frac{2}{3} (16+r^2)^\frac{3}{2}]_0^1\)

                  \(=\sqrt{17} -\frac{2}{3} ((17)^\frac{3}{2} -(16)^\frac{3}{2} )\)

                  \(=0.0612\)

Hence, the integral value is 0.0612.

Find the 99% confidence interval for the population mean when the population standard deviation is three and the sample mean is six. Assume the population has a normal distribution and 10 items are in the sample. (3.52, 8.48) (2.74, 9.26) (3.56, 8.44) (4.14, 7.86)

Answers

The 99% confidence interval for the population mean is approximately (3.56, 8.44).

To find the 99% confidence interval for the population mean, we can use the formula:

Confidence interval = sample mean ± (critical value) × (standard deviation / √(sample size))

In this case, the population standard deviation is 3, the sample mean is 6, and the sample size is 10.

To find the critical value, we need to determine the z-score associated with a 99% confidence level.

Since the confidence level is 99%, we need to find the z-score that leaves 1% of the area in the tails of the normal distribution.

The remaining 99% is divided equally between the two tails, so each tail has an area of 0.5%.

Using a standard normal distribution table or calculator, we can find the z-score associated with the 0.5% tail area, which is approximately 2.576.

Plugging the values into the formula, we have:

Confidence interval = 6 ± (2.576)  (3 / √(10))

Calculating this, we get:

Confidence interval = 6 ± 2.576 × 3 / √(10) ≈ 6 ± 2.576 × 0.948683 ≈ 6 ± 2.44597

Therefore, the 99% confidence interval for the population mean is approximately (3.56, 8.44).

Answers

Using the master theorem, the time complexity of the given recurrence relation T(N) - 9T(N/9)+N(IgN) has been found. The answer is T(n) = Θ(nlogb(a)) = Θ(n * log n), which implies that the time complexity is of O(nlog n).

For the given recurrence relation, T(n) - 9T(n/9)+N(IgN), we have to find the time complexity using the master theorem, which is given below:

Master Theorem:

Consider a recurrence relation T(n) = aT(n/b) + f(n), where a ≥ 1, b > 1 and f(n) is an asymptotically positive function. Then, we have the following cases:

Case 1: If f(n) = O(nᵏ) for some constant k < logb(a), then T(n) = Θ(nlogb(a)).

Case 2: If f(n) = Θ(nᵏlogm(n)) for some constant k = logb(a), then T(n) = Θ(nᵏlog(m+1)n).

Case 3: If f(n) = Ω(nᵏ) for some constant k > logb(a), and if a.f(n/b) ≤ cf(n) for some constant c < 1 and sufficiently large n, then T(n) = Θ(f(n)).

In the given recurrence relation, we have a = 9, b = 9 and f(n) = n * log n.

Comparing a with bᵏ, we get a = bᵏ.

∴ k = 1

Taking log with base 9 on both sides, we get:

log₉T(n) = log₉(9T(n/9) + n * log n)log₉T(n) = log₉9 + log₉T(n/9) + log₉n * log₉log(n)log₉

T(n) = 1 + log₉T(n/9) + log₉n * log₉log(n)For f(n) = n * log(n), nᵏ = n¹, so k = 1 > 0.

Therefore, according to master's theorem, T(n) = Θ(n * log n).

Using the master theorem, the time complexity of the given recurrence relation T(N) - 9T(N/9)+N(IgN) has been found. The answer is T(n) = Θ(nlogb(a)) = Θ(n * log n), which implies that the time complexity is of O(nlog n).

Answers

Yes, 12 refrigerators and 11 pianos overload the truck, because 12 refrigerators and 11 pianos weighs more than 7100 lb.

What are inequalities?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, a truck that can carry no more than 7100 lb is being used to transport refrigerators and upright pianos

Let the number of refrigerators be x and the number of pianos be y.

Each refrigerator weighs 250 lb and each piano weighs 425 lb.

Here, 250x+425y≤7100

Will 12 refrigerators and 11 pianos overload the truck

Now, put x=12 and y=11 in the inequality 250x+425y≤7100, we get

250×12+425×11≤7100

x = 0, y = -3

x = 1, y = -1

x = 2, y = 1

x = 3, y = 5

These are six sets of integer values that satisfy the inequality |x-y|>2. In each case, the absolute value of the difference between x and y is greater than 2, which satisfies the inequality. For example, in the first set, x = -1 and y = -5, so the absolute value of the difference is |-1 - (-5)| = |-1 + 5| = 6, which is greater than 2. In the second set, x = 0 and y = -3, so the absolute value of the difference is |0 - (-3)| = |0 + 3| = 3, which is greater than 2. Similarly, the other sets of values also satisfy the inequality.

Answers

The factor that provides the basis for the grading of newly diagnosed malignant tumours is degree of differentiation.

What is the degree of differentiation?

The level of differentiation impacts an individual's capacity to control their emotions, thoughts, individuality, and connections to others. The degree of any differential equation can be obtained when it is expressed as a polynomial; otherwise, the degree cannot be defined.

The mechanisms by which immature cells develop into mature cells with particular roles are described in biology. This indicates the degree to which tumour tissue resembles the healthy tissue from which it originated in the context of cancer. Compared to poorly or undifferentiated cancer cells, well-differentiated cancer cells resemble normal cells more and grow and spread more slowly. Tumour grading systems, which vary for each form of cancer, use differentiation.

The Extreme value theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval.

(a) If f is not continuous, the Extreme Value Theorem does not hold. Here is a sketch to illustrate this:

In the graph above, the function f(x) has a vertical asymptote at x = 0 and a hole at x = 1. The function is not continuous on the interval [0, 2], so the Extreme Value Theorem does not apply.

There is no global minimum or maximum on the interval, as the function keeps increasing as x approaches 0 and keeps decreasing as x approaches 2.

(b) If [a, b] is replaced with (a, b], the Extreme Value Theorem does not hold. Here is a sketch to illustrate this:

In the graph above, the function f(x) is defined on the open interval (0, 1]. The function has a horizontal asymptote at y = 0 and a local maximum at x = 1/2.

However, there is no global maximum on the interval (0, 1], since the function keeps increasing without bound as x approaches 0.

Carlo has 8 3/4 yard of material. She needs to use 1/3 of the material to make a dress. How many yards of material will she need to make the dress?

Answers

We have that:

• Carlo has 8 3/4 yards of material

,

• She needs to use 1/3 of the material to make a dress

Then we need to determine the number of yards of material she needs to make a dress.

To find it, we can proceed as follows:

1. We have that the total of material is:

\(8\frac{3}{4}\)

2. And this mixed fraction is equivalent to the next improper fraction:

\(\begin{gathered} 8\frac{3}{4}=8+\frac{3}{4} \\ \\ \end{gathered}\)

3. We also know that the formula to add two fractions is as follows:

\(\begin{gathered} \frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bd} \\ \\ \text{ Then we have:} \\ \\ 8+\frac{3}{4}=\frac{8}{1}+\frac{3}{4}=\frac{8(4)+3(1)}{1(4)}=\frac{32+3}{4}=\frac{35}{4} \\ \\ \therefore8\frac{3}{4}=\frac{35}{4} \end{gathered}\)

4. Now, to find the third part, we already know that the third part of a number is the number times 1/3 (or vice-versa). Then we have:

\(\begin{gathered} \frac{1}{3}*n\Rightarrow \\ \\ \frac{1}{3}*\frac{35}{4}=\frac{1(35)}{3(4)}=\frac{35}{12} \\ \\ \end{gathered}\)

Therefore, Carlo needs 35/12 yards of material to make the dres

Find the curve length of C: x=cos3t,y=sin3t;0≤t≤π/2

Answers

the curve length of C over the interval 0 ≤ t ≤ π/2 is (3π/2) units.

What is Parametric curve?

To find the curve length of the curve C defined by the parametric equations x = cos(3t) and y = sin(3t), where t ranges from 0 to π/2, we can use the arc length formula for parametric curves.

The arc length formula for a parametric curve defined by x = f(t) and y = g(t), where a ≤ t ≤ b, is given by:

\(L = ∫[a, b] √[ (dx/dt)^2 + (dy/dt)^2 ] dt\)

Let's calculate the arc length for the given curve C:

x = cos(3t)

y = sin(3t)

First, we need to find the derivatives dx/dt and dy/dt:

dx/dt = -3sin(3t)

dy/dt = 3cos(3t)

Now, let's substitute these derivatives into the arc length formula:

\(L = ∫[0, π/2] √[ (-3sin(3t))^2 + (3cos(3t))^2 ] dt\)

\(L = ∫[0, π/2] √[ 9sin^2(3t) + 9cos^2(3t) ] dtL = ∫[0, π/2] 3 √[ sin^2(3t) + cos^2(3t) ] dtL = ∫[0, π/2] 3 dtL = 3[t] from 0 to π/2L = 3(π/2 - 0)L = 3π/2\)

Therefore, the curve length of C over the interval 0 ≤ t ≤ π/2 is (3π/2) units.

A water taxi carries passengers from harbor to another. Assume that weights of passengers are normally distributed with a mean of 200lb and a standard deviation of 35lb. The water taxi has a stated capacity of 25 passengers, and the water taxi was rated for a load limit of 3750lb. Complete parts (a) through (d) below. a. Given that the water taxi was rated for a load limit of 3750lb, what is the maximum mean weight of the passengers if the water taxi is filled to the stated capacity of 25 passengers? The maximum mean weight is lb. (Type an integer or a decimal. Do not round.) b. If the water taxi is filled with 25 randomly selected passengers, what is the probability that their mean weight exceeds the value from part (a)? The probability is (Round to four decimal places as needed.) c. If the weight assumptions were revised so that the new capacity became 20 passengers and the water taxi is filled with 20 randomly selected passengers, what is the probability that their mean weight exceeds 187.5lb, which is the maximum mean weight that does not cause the total load to exceed 3750lb ? The probability is (Round to four decimal places as needed.) d. Is the new capacity of 20 passengers safe?

Answers

a) The maximum mean weight is 150lb. b) The probability is approximately 0.0062. c) The probability is approximately 0.9764. d) The new capacity of 20 passengers does not appear to be safe as the probability of exceeding the load limit is high.

a) To find the maximum mean weight, we divide the load limit of 3750lb by the stated capacity of 25 passengers: 3750lb / 25 passengers = 150lb. Therefore, the maximum mean weight of the passengers should not exceed 150lb to stay within the load limit.

b) To find the probability that the mean weight of 25 randomly selected passengers exceeds 150lb, we need to calculate the probability of the sample mean being greater than 150lb. Since the sample mean follows a normal distribution, we can use the standard deviation of the population (35lb) divided by the square root of the sample size (√25) to calculate the standard error. With this information, we can calculate the z-score and find the probability using a standard normal distribution table or a statistical calculator. The probability is approximately 0.0062.

c) If the capacity is revised to 20 passengers, we need to find the new maximum mean weight that does not exceed the load limit. Given that the load limit is 3750lb and the capacity is 20 passengers, we divide the load limit by the new capacity: 3750lb / 20 passengers = 187.5lb. To find the probability that the mean weight of 20 randomly selected passengers exceeds 187.5lb, we can use a similar approach as in part b. The probability is approximately 0.9764.

d) The new capacity of 20 passengers does not appear to be safe because the probability of exceeding the load limit is high (approximately 0.9764). This indicates a significant risk of exceeding the load limit if the mean weight of the passengers is greater than 187.5lb. Therefore, it would be advisable to reconsider the capacity or take additional precautions to ensure passenger safety and avoid exceeding the load limit.

Select the correct answer. Positive Test Negative Test Subject is diabetic 35 3 Subject is not diabetic 5 28 A test subject is randomly selected for a diabetes test. What is the probability of getting a subject who is not diabetic, given that the test result is negative? Find the probability using the data table. A. 0.10 B. 0.12 C. 0.50 D. 0.90

Answers

The probability of getting a subject who is not diabetic, given that the test result is negative, is approximately 0.1786.

To find the probability of getting a subject who is not diabetic, given that the test result is negative, we can use the data provided in the table. From the table, we can see that out of the total subjects tested, 5 are not diabetic and have a negative test result. The total number of subjects with a negative test result is 28.

To calculate the probability, we divide the number of subjects who are not diabetic and have a negative test result (5) by the total number of subjects with a negative test result (28).

Probability = Number of subjects who are not diabetic and have a negative test result / Total number of subjects with a negative test result

Probability = 5 / 28

Simplifying this fraction, we get:

Probability ≈ 0.1786

Therefore, the probability of getting a subject who is not diabetic, given that the test result is negative, is approximately 0.1786.
