The critical points are x = π/4 and x = 3π/4, and the extreme values on the interval [0,2] are 1/2 and -1/2,

To find the critical points of f(x) = 2 sin(x) cos(x) on the interval [0, 2] and determine the extreme values, we will first take the derivative of the function and set it equal to zero to find the critical points.

f(x) = 2 sin(x) cos(x)

f'(x) = 2 cos(x) cos(x) - 2 sin(x) sin(x) (using the product rule)

[tex]f'(x) = 2(cos^2(x) - sin^2(x))[/tex]

f'(x) = 2(cos(2x))

Setting f'(x) equal to zero to find the critical points, we get:

2(cos(2x)) = 0

cos(2x) = 0

2x = π/2, 3π/2, 5π/2

x = π/4, 3π/4, 5π/4

Only the values x = π/4 and x = 3π/4 are in the interval [0,2], so these are the critical points.

Next, we need to determine the extreme values of f(x) at these critical points and the endpoints of the interval [0,2].

We can do this by evaluating the function at these points and comparing the values.

f(0) = 0

f(π/4) = 2(sin(π/4)cos(π/4)) = sin(π/2)/2 = 1/2

f(3π/4) = 2(sin(3π/4)cos(3π/4)) = -sin(π/2)/2 = -1/2

f(2) = 0

Therefore, the function has a maximum value of 1/2 at x = π/4 and a minimum value of -1/2 at x = 3π/4.

There are no extreme values at the endpoints of the interval [0,2].

Thus, the critical points are x = π/4 and x = 3π/4, and the extreme values on the interval [0,2] are 1/2 and -1/2, respectively.

The final answer is: π/4, 3π/4, 1/2, -1/2

If you're gonna write. just write the numbers and equations...

a. To find the probability that daily sales will fall between 2,500 and 3,000 gallons, we need to find the proportion of the total area under the probability distribution curve that lies between 2,500 and 3,000 gallons. Since the distribution is uniform, the probability density function is constant over the interval [2,000, 5,000] and equals 1/(5,000 - 2,000) = 1/3,000. Thus, the probability of selling between 2,500 and 3,000 gallons is:

P(2,500 ≤ X ≤ 3,000) = (3,000 - 2,500) / (5,000 - 2,000) = 0.1667

Therefore, the probability that daily sales will fall between 2,500 and 3,000 gallons is approximately 0.1667 or 16.67%.

b. To find the probability that the service station will sell at least 4,000 gallons, we need to find the proportion of the total area under the probability distribution curve that lies to the right of 4,000 gallons. This can be computed as:

P(X ≥ 4,000) = (5,000 - 4,000) / (5,000 - 2,000) = 0.3333

Therefore, the probability that the service station will sell at least 4,000 gallons is approximately 0.3333 or 33.33%.

c. Since the distribution is continuous, the probability of selling exactly 2,500 gallons is zero. This is because the probability of any single point in a continuous distribution is always zero, and the probability of selling exactly 2,500 gallons corresponds to a single point on the distribution curve.

To find the p-values for which this series converges, we need to use the p-test for convergence of a series.

The p-test states that if the series ∑n^p converges, then p must be greater than 1. If p is less than or equal to 1, then the series diverges.

Using this information, we can see that for the given series, we have p = 4(1-5^-p).

We want to find the values of p for which this series converges, so we need to solve for p.

4(1-5^-p) > 1

1-5^-p > 1/4

-5^-p > -3/4

5^-p < 3/4

-plog(5) < log(3/4)

p > log(4/3)/log(5)

So the p-values for which the series converges are all values of p greater than log(4/3)/log(5).

The method-of-moments estimators of μ and σ² are μ = sample mean,
σ² = sample second moment - sample mean².

To find the method-of-moments estimators of μ and σ², we need to first calculate the first and second moments of the normal distribution.

The first moment is simply the mean , which is equal to μ.

The second moment is the variance plus the square of the mean, which is equal to σ² + μ².

To estimate μ, we can set the sample mean equal to the population mean μ, and solve for μ:

sample mean = μ
μ = sample mean

To estimate σ², we can set the sample second moment equal to the population second moment, and solve for σ²:

sample second moment = σ² + μ²
σ² = sample second moment - μ²

Therefore, the method-of-moments estimators of μ and σ² are:

To find the union of B, we need to consider all elements in any Bn. Since Bn excludes the first n natural numbers, the union will include all natural numbers greater than n for all n. In other words, the union will contain all natural numbers.

Union(B) = N

b) Intersection of B:

To find the intersection of B, we need to consider elements common to all Bn. Observe that, as n increases, Bn excludes more natural numbers. Therefore, there will be no natural numbers common to all Bn.

Intersection(B) = ∅

The resulting plot will show the temperature distribution along the rod, with higher temperatures near the left end and lower temperatures near the right end due to the boundary conditions.

To solve this equation using the shooting method, we first need to convert it into a system of first-order differential equations. Let u = dt/dx. Then we have:

du/dx = 10^-7(t-273)^4 - 4(150-t)u
dt/dx = u

subject to the boundary conditions:

t(0) = 200
t(0.5) = 100

Now we can use the shooting method to solve this system numerically. We start by guessing an initial value for u(0), which we'll call u0. We then integrate the system from x=0 to x=0.5 using a numerical method such as the Runge-Kutta method.

We compare the resulting value of t(0.5) to the desired value of 100. If they don't match, we adjust our guess for u0 and try again until we get the correct value.

To plot the results, we can use any plotting software such as MATLAB or Python. We can plot the temperature T vs x for the range 0 <= x <= 0.5.

The resulting plot will show the temperature distribution along the rod, with higher temperatures near the left end and lower temperatures near the right end due to the boundary conditions.

1. The probability of getting one 1 is 0.5177

2. The probability of getting at least one snake-eyes in 24 throws is 0.4907.

To find the probability of getting at least one 1 when throwing 4 dice, we can first find the probability of not getting any 1s and then subtract that from 1.

There are 6 sides on a die, and 5 sides are not 1. The probability of not getting a 1 in a single die throw is 5/6. Since the dice are independent, the probability of not getting any 1s when throwing 4 dice is (5/6)^4.

Now, we can find the probability of getting at least one 1:

P(at least one 1) = 1 - P(no 1s) = 1 - (5/6)^4 = 0.5177

b) To find the probability of getting at least one snake-eyes (1,1) when throwing 2 dice 24 times, we can first find the probability of not getting any snake-eyes in 24 throws and then subtract that from 1.

The probability of not getting snake-eyes in a single throw of 2 dice is 1 - 1/36 = 35/36, since there are 36 possible outcomes and only 1 of them is snake-eyes.

Now, we can find the probability of not getting any snake-eyes in 24 throws of 2 dice:

P(no snake-eyes in 24 throws) = (35/36)^24 = 0.5093

Finally, we can find the probability of getting at least one snake-eyes in 24 throws:

P(at least one snake-eyes) = 1 - P(no snake-eyes in 24 throws) = 1 - 0.5093 = 0.4907

A statistic is a numerical summary of a sample, which is a subset of a larger population. Statistics are used in a wide range of fields, including business, economics, social sciences, and more.

The t-statistic is a measure of the difference between a sample mean and a population mean, divided by the standard error of the sample mean. It is used in hypothesis testing to determine if the difference between the two means is significant.

According to the given information:

16) This is a two-sample t statistic.

17 )The conservative degrees of freedom for this statistic can be calculated using the formula: df = (n1 - 1) + (n2 - 1), where n1 and n2 are the sample sizes of the two groups. In this case, the sample sizes are 7 and 6, so the degrees of freedom are (7-1) + (6-1) = 11.

18) To show that this t leads to the quoted conclusion, we need to calculate the p-value for the test. Since the t statistic is negative, we will use a one-tailed test to calculate the p-value. Using a t-distribution table or software, we can find that the p-value for a one-tailed t-test with 11 degrees of freedom and a t-statistic of -1.05 is approximately 0.16. Therefore, we can conclude that the difference between the two groups is not statistically significant at the alpha = 0.05 level, and the reported conclusion is correct.

19) Answer: C. 0.15 < P < 0.20

The distribution we would use to look up the p-value is option (c) t(15).

Since the population standard deviation is unknown and the sample size is less than 30, we should use a t-distribution to look up the p-value.

The test statistic can be calculated as

t = (sample mean - hypothesized population mean) / (sample standard deviation / √(sample size))

Substitute the values in the equation

t = (1988 - 2000) / (32 / √(16))

Jakob's function states that the number of circles needed to make the nth figure is equal to the number of circles needed to make the (n-1)th figure plus 4. This implies that for each subsequent figure, 4 more circles are added to the previous figure.

As given C(1) = 1, then according to Jakob's function,

C(2) = C(1) + 4 = 1 + 4 = 5,

C(3) = C(2) + 4 = 5 + 4 = 9, and so on.

This matches the pattern where each figure requires 4 more circles than the previous figure. Therefore, Jakob's function represents the number of circles needed to make the nth figure in the pattern.

Thus, Jakob's function C(n) = C(n-1) + 4 accurately represents the number of circles needed to make the nth figure in the given pattern with each figure using 4 more circles than previous one

The given table presents a step-by-step explanation of the proof that ΔPQR and ΔSTU are similar triangles. The proof uses the definition of similar polygons, the congruence and similarity postulates, and the properties of equality.

The first two statements state that ΔPQR and ΔSTU are given and that ∠P ≅ ∠S, ∠Q ≅ ∠T, ∠R ≅ ∠U, respectively. These are given as part of the problem.

The third statement asserts that ΔPQR is similar to ΔSTU. This follows from the fact that the corresponding angles of the two triangles are congruent, which is stated in the second statement. This is one of the criteria for the similarity of two triangles, known as the Angle-Angle (AA) Similarity Theorem.

Therefore, the fourth statement defines the concept of similar polygons, which are polygons that have the same shape but may differ in size.

The statement is generally true.

The binomial distribution is a probability distribution that describes the number of successes in a fixed number of independent trials, where each trial can either result in a success or a failure

According to the given information:

The statement is generally true. According to the Central Limit Theorem, as the sample size increases, the distribution of sample means approaches a normal distribution. In the case of a binomial distribution, the sample mean represents the proportion of successes in the sample. Therefore, when the sample size is large enough (typically n ≥ 30), the distribution of sample proportions closely approximates a normal distribution, and the mean and standard deviation of the sample proportion can be used to approximate the mean and standard deviation of a normal distribution. However, there may be cases where the normal approximation is not appropriate due to skewness or other factors, so it is always important to consider the context and assumptions of the problem.

The volume of the solid region bounded on the top by the paraboloid z = 6 - x^2 - y^2 and bounded on the bottom by the cone z = sqrt(x^2 + y^2) is 9π cubic units.

In cylindrical coordinates, the paraboloid and the cone can be expressed as Paraboloid is z = 6 - r^2 and Cone is z = r.

To find the volume of the solid region bounded by these surfaces, we need to integrate over the appropriate limits. Since the cone lies below the paraboloid, we need to integrate from the bottom of the cone to the top of the paraboloid.

The limits of integration for r are 0 to 6^(1/2)cos(theta) since the cone intersects the paraboloid when z=r, giving r = 6^(1/2)sin(theta) and z = 6 - r^2.

The limits of integration for theta are 0 to 2pi since we need to cover the full circle.

The limits of integration for z are r to 6 - r^2.

Therefore, the volume of the solid is given by the triple integral

V = ∫∫∫ r dz dr dθ, where the limits of integration are:

0 ≤ r ≤ 6^(1/2)cos(theta)

0 ≤ θ ≤ 2π

r ≤ z ≤ 6 - r^2

Solving the triple integral,

V = ∫∫∫ r dz dr dθ

= ∫0^2π ∫0^6^(1/2)cos(theta) ∫r^(6-r^2) r dz dr dθ

= ∫0^2π ∫0^6^(1/2)cos(theta) (3r^2 - r^4) dr dθ

= ∫0^2π (9/2 - 2/5 cos^2(theta)) dθ

= 9π

Therefore, the volume of the solid region is 9π cubic units.

For the differential equation xy' + y = 10√x, the general solution is obtained as [tex]y(ln|x| - 1) = 20x^{(\frac{1}{2})} + C[/tex].

What is differential equation?

Any equation with one or more terms and one or more derivatives of the dependent variable with respect to the independent variable is referred to as a differential equation.

We can solve this differential equation using separation of variables. First, we rewrite the equation as -

y' + y/x = 10√(x)/x

Now, we separate the variables and integrate both sides -

∫(y' + y/x) dx = ∫10√(x)/x dx

Integrating the left side with respect to x gives -

∫(y' + y/x) dx = ∫(ln|x|)'y dx

y ln|x| = ∫y' dx

y ln|x| = y + C1

y (ln|x| - 1) = C1

Integrating the right side with respect to x gives -

[tex]\int10\frac{\sqrt{x}}x}dx = 20x^{(\frac{1}{2})} + C2[/tex]

Putting everything together, we have -

[tex]y(ln|x| - 1) = 20x^{(\frac{1}{2})} + C[/tex]

where C = C1 + C2.

This is the general solution to the differential equation.

Therefore, the solution is [tex]y(ln|x| - 1) = 20x^{(\frac{1}{2})} + C[/tex]

When x=-5, dy/dt = -700 and  When x=2, dy/dt = 0.

To find dy/dt when x=-5, we first need to differentiate y with respect to t using the chain rule:

dy/dt = (dy/dx) * (dx/dt)

Using the power rule and product rule for differentiation, we can find:

dy/dx = 6[tex]x^{2}[/tex] + 2x
dx/dt = -5 (since x is given as -5)

Substituting these values into the chain rule equation, we get:

dy/dt = (6(-5[tex])^{2}[/tex] + 2(-5)) * (-5) = -700

Therefore, when x=-5, dy/dt = -700.

To find dy/dt when x=2, we can use the same method:

dy/dx = 6[tex]x^{2}[/tex] + 2x
dx/dt = 0 (since x is constant)

Substituting these values into the chain rule equation, we get:

dy/dt = (6(2[tex])^{2}[/tex] + 2(2)) * 0 = 0

Therefore, when x=2, dy/dt = 0.
