In the given figure, shape A is cone and shape B is cylinder. Therefore, option C is the correct answer.

A cone is a three-dimensional shape with a flat base (typically circular) that gradually narrows to a point at the top, called the apex or vertex. It is formed by a set of lines or half-lines extending from the apex to all points lying on a plane that does not contain the apex.

A cylinder is a three-dimensional figure that is made up of two parallel flat surfaces connected by a curved side. The two bases are typically circular, but can also be any other shape, such as an ellipse. The two bases are usually at different heights and the curved surface is made up of straight side walls connecting the two bases. Cylinders can be thought of as a circular tube that has been cut in half and then the cut edges pushed together.

Therefore, option C is the correct answer.

a.  The probability that exactly 3 parts will be defective is 26.1%.

b. The probability that the number of defective parts will be more than 2 but fewer than 6 is 35.7%.

c. The probability that fewer than 4 parts will be defective is 75.9%.

d. The expected number of defective parts is 0.8.

e. The variance for the number of defective parts is 0.784.

a. To find the probability that exactly 3 parts will be defective, we need to use the binomial probability formula:

P(x = 3) = (n choose x) * p^x * (1-p)^(n-x)

where n is the number of parts selected (40), p is the probability of a part being defective (0.02), and x is the number of defective parts we're interested in (3).

Plugging in the values, we get:

P(x = 3) = (40 choose 3) * 0.02^3 * (1-0.02)^(40-3)

P(x = 3) ≈ 0.261

So the probability that exactly 3 parts will be defective is approximately 0.261 or 26.1%.

b. To find the probability that the number of defective parts will be more than 2 but fewer than 6, we need to add up the probabilities of having 3, 4, or 5 defective parts:

P(3 ≤ x ≤ 5) = P(x = 3) + P(x = 4) + P(x = 5)

Using the same formula as before, we can calculate each of these probabilities:

P(x = 4) = (40 choose 4) * 0.02^4 * (1-0.02)^(40-4) ≈ 0.091

P(x = 5) = (40 choose 5) * 0.02^5 * (1-0.02)^(40-5) ≈ 0.005

So:

P(3 ≤ x ≤ 5) ≈ 0.261 + 0.091 + 0.005 ≈ 0.357

Therefore, the probability that the number of defective parts will be more than 2 but fewer than 6 is approximately 0.357 or 35.7%.

c. To find the probability that fewer than 4 parts will be defective, we can add up the probabilities of having 0, 1, 2, or 3 defective parts:

P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)

We already know P(x = 3) from part a, so we just need to calculate the other probabilities using the same formula:

P(x = 0) = (40 choose 0) * 0.02^0 * (1-0.02)^(40-0) ≈ 0.112

P(x = 1) = (40 choose 1) * 0.02^1 * (1-0.02)^(40-1) ≈ 0.296

P(x = 2) = (40 choose 2) * 0.02^2 * (1-0.02)^(40-2) ≈ 0.351

So:

P(x < 4) ≈ 0.112 + 0.296 + 0.351 + 0.261 ≈ 1.02

However, we shouldn't include P(x = 3) in this calculation, since it's already counted in P(x < 5). So we need to subtract it out:

P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2)

P(x < 4) ≈ 0.112 + 0.296 + 0.351 ≈ 0.759

Therefore, the probability that fewer than 4 parts will be defective is approximately 0.759 or 75.9%.

d. The expected number of defective parts can be found using the formula:

E(x) = n * p

where n and p are as before: n = 40, p = 0.02.

E(x) = 40 * 0.02 = 0.8

Therefore, we expect an average of 0.8 defective parts out of 40.

e. The variance for the number of defective parts can be found using the formula:

Var(x) = n * p * (1-p)

Var(x) = 40 * 0.02 * (1-0.02) ≈ 0.784

Therefore, the variance for the number of defective parts is approximately 0.784.

= 3.75 Standard deviation,

σ = √(npq)

= √(5 x 0.75 x 0.25)

= √0.9375

= 0.9682.

Therefore, the mean number of peas with green pods is 3.75 and the standard deviation is 0.9682 when groups of 5 offspring peas are generated, assuming a 0.75 probability that an offspring pea has a green pod. Probability theory is used to model and analyze random phenomena. The Binomial Distribution is one of the most common probability distribution functions that we use when dealing with a situation in which there are only two outcomes, such as tossing a coin, rolling a die, or selecting an item from a box. In this question, we have to find the mean and standard deviation of the number of peas with green pods when groups of 5 offspring peas are generated, and there is a 0.75 probability that an offspring pea has a green pod.

Using the Binomial Distribution formula, we get: Mean, μ = np Standard deviation, σ = √(npq) Where, n is the total number of trials (5),p is the probability of success (0.75), and q is the probability of failure (1 - p = 0.25).Mean, μ = np

= 5 x 0.75 = 3.75 Standard deviation,

σ = √(npq)

= √(5 x 0.75 x 0.25)

= √0.9375

= 0.9682 Therefore, the mean number of peas with green pods is 3.75 and the standard deviation is 0.9682 when groups of 5 offspring peas are generated, assuming a 0.75 probability that an offspring pea has a green pod. The mean tells us the average number of peas with green pods that we can expect to get when generating groups of 5 offspring peas. The standard deviation tells us how much the actual number of peas with green pods can vary from the mean.

f(x) is an exponential function with an initial value of 33,966.17 and a decay rate of 0.310, which matches the trend of the data.

We can plot the data points and look for a pattern to see if an exponential or linear function better fits the provided data.

The provided data point can first be plotted as a scatter plot.

(1, 16890.32) (2, 14259.09) (3, 12001.57) (4, 10051.16)

To find the specific exponential function that would fit this data, we can use the formula for exponential decay:

f(x) = a * \(e^(-bx)\)

where f(x) is the value of the investment at time x, a is the initial value of the investment, and b is the decay rate.

Using the given data, we can plug in the values for f(x) and x to solve for a and b. Here is the calculation:

16,890.32 = a * \(e^(-b1)\)

14,259.09 = a * \(e^(-b2)\)

12,001.57 = a * \(e^(-b3)\)

10,051.16 = a * \(e^(-b4)\)

Dividing the second equation by the first, and the third equation by the second, and so on, we can get rid of the constant a:

14,259.09/16,890.32 = \(e^(-b)\)

12,001.57/14,259.09 = \(e^(-b)\)

10,051.16/12,001.57 = \(e^(-b)\)

Taking the natural logarithm of both sides, we get:

ln(14,259.09/16,890.32) = -b

ln(12,001.57/14,259.09) = -b

ln(10,051.16/12,001.57) = -b

Simplifying these equations, we get:

b ≈ 0.310

a ≈ 33,966.17

So the exponential function that best models this data is:

f(x) = 33,966.17 * \(e^(-0.310x)\)

This function has an initial value of 33,966.17 and a decay rate of 0.310, which matches the trend of the given data.

The integral ∫[0,1]∫[1,2] x^2 f(x, y) dy dx can be interpreted as the double integral over the region defined by the limits of integration: x ranging from 0 to 1 and y ranging from 1 to 2. To sketch this region, we can visualize a rectangular region in the xy-plane bounded by the lines x = 0, x = 1, y = 1, and y = 2.

Now, to change the order of integration, we need to swap the order of the integrals. Instead of integrating with respect to y first and then x, we will integrate with respect to x first and then y.

The new order of integration will be ∫[1,2]∫[0,1] x^2 f(x, y) dx dy. This means that we will integrate with respect to x over the interval [0,1], and for each value of x, we will integrate with respect to y over the interval [1,2].

Changing the order of integration can sometimes make the evaluation of the integral more convenient or allow us to use different techniques to solve it.

\((a^\frac{2}3} b^\frac{1}{3})^\frac{1}{2}\)

\(a^\frac{2}3}^*^ \frac{1}{2} *b^\frac{1}{3}^*^\frac{1}{2}\)

\(a^\frac{2*1}{3*2} * b^\frac{1*1}{3*2}\)

\(a^\frac{2}{6} * b^\frac{1}{6}\)

The net of a triangular prism consists of two triangles and three rectangles.

In the net of a triangular prism, we can observe two types of polygons: triangles and rectangles.

First, let's discuss the triangles.

A triangular prism has two triangular faces, which are congruent to each other.

These triangles are equilateral triangles, meaning they have three equal sides and three equal angles.

Each of these triangles contributes two polygons to the net, one for each face.

Next, we have the rectangles.

A triangular prism has three rectangular faces that connect the corresponding sides of the triangular bases.

These rectangles have opposite sides that are parallel and equal in length.

Each rectangle contributes one polygon to the net, resulting in a total of three rectangles.

To summarize, the net of a triangular prism consists of two equilateral triangles and three rectangles.

The triangles represent the bases of the prism, while the rectangles form the lateral faces connecting the bases.

Altogether, there are five polygons in the net of a triangular prism.

It's important to note that the dimensions of the polygons may vary depending on the specific size and proportions of the triangular prism, but the basic shape and number of polygons remain the same.
