Answer:

The area under a curve between two points can be found by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b. Areas under the x-axis will come out negative and areas above the x-axis will be positive.

Answer:

103.5°

Step-by-step explanation:

Let "x" represent the missing angle.

Vertex formed = ½(the sum of the intercepted arcs) based on the intersecting chords theorem.

Therefore:

m<x = ½(195 + 12)

m<x = ½(207)

m<x = 103.5

MIssing angle is therefore 103.5°

Answer put the question smarty

Step-by-step explanation:

Answer:

0.84 = 84% probability that fewer than 3 of the parts are defective.

Step-by-step explanation:

For each part, there are only two possible outcomes. Either it is defective, or it is not. The probability of a part being defective is independent of any other part, and thus, the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

A machine that manufactures automobile parts produces defective parts 16% of the time.

This means that [tex]p = 0.16[/tex]

9 parts:

This means that [tex]n = 9[/tex]

What is the probability that fewer than 3 of the parts are defective?

This is:

[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{9,0}.(0.16)^{0}.(0.84)^{9} = 0.2082[/tex]

[tex]P(X = 1) = C_{9,1}.(0.16)^{1}.(0.84)^{8} = 0.3569[/tex]

[tex]P(X = 2) = C_{9,2}.(0.16)^{2}.(0.84)^{7} = 0.2720[/tex]

[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.2082 + 0.3569 + 0.2720 = 0.8371[/tex]

Rounding to two decimal places, 0.84.

0.84 = 84% probability that fewer than 3 of the parts are defective.

The horizontal asymptote is y=-0.5.

How to find horizontal asymptote?

If the degree of the polynomial in the numerator and the denominator is same then the horizontal asymptote is given by [tex]y=\frac{\text{leading coefficient of the numerator}}{\text{ leading coefficient of the denominator}}[/tex]

In the given function, the degree of the polynomial of the numerator is 2 and of the denominator is also 2.

The leading coefficient in the numerator is -5 and in the denominator it is 10.

Divide -5 by 10 and equate the result to y to get the horizontal asymptote .

[tex]y=\frac{-5}{10}[/tex]

y=-0.5

Therefore, the correct option is b.

The shape of the probability histogram of X is skewed right.

The correct answer is (B)

Skewness refers to a distortion or asymmetry that deviates from the symmetrical bell curve, or normal distribution, in a set of data.

As, English test has 50 multiple-choice questions, each with five answer choices and one correct answer.

Let X represent the number of questions answered correctly.

In statistics, a positively skewed (or right-skewed) distribution is a type of distribution in which most values are clustered around the left tail of the distribution while the right tail of the distribution is longer.

By looking the condition given in the questions, we can say that the shape will be skewed right on histogram.

Answer:

Volume of a Cylinder:

In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.

The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.

Remember that the radius and the height must be in the same units - convert them if necessary.

The resulting volume will be in those cubic units. So if the height and radius are both in centimeters, then the volume will be in cubic centimeters.

The volume of a cylinder is found by multiplying the area of its top or base by its height and is defined as: V = π· r2· h

Example 1: A cylindrical water storage tank has an inside base radius of 7m and depth of 11 m. Find the capacity of the tank in kiloliters (1kl = 1m3).

Solution:

Base radius: r = 7 m

Height: h = 11 m

The water storage tank is in the shape of the cylinder. So using the volume of cylinder formula we can find the volume of it.

V = π· r2· h

V = π· 72· 11

V = 1692.46 m3 = 1692.46 kl

Example 2: Find the volume of a cylinder whose base radius is 6 cm and height is 4 cm.

Solution:

Base radius: r = 6 cm

Height: h = 4 cm

V = π· r2· h

V = 3.14· 62· 4

V = 452.16 cm3

Example 3: If the capacity of a cylindrical tank is 1848 m3 and the diameter of its base is 14 m, find the depth of the tank.

Solution:

Let the depth of the tank be h metres. Then we have:

V = π· r2· h

h = V / π· r2

h = 12 m

Example 4: A conical vessel, whose internal radius and height is 20cm and 50 cm respectively, is full of liquid. Find the height of the liquid if it is put into a cylinder whose base radius is 10 cm.

Solution:

The volume of the vessel is:

V = π ∙ r2 ∙ h / 3

V = π · 202· 50 / 3

V = 20944 cm3

The volume of the liquid is the same no matter it is in the vessel or in the cylinder, therefore we have:

V1 = V2, where V1 is the volume of the vessel and V2 is the volume determined using the formula for a cylinder.

20944 = π · 102 · h

Thus:

h = 20944 / (π · 102)

h = 66.67 cm

Example 5: Find the volume of a right circular cylinder whose curved surface area is 2640 cm2

And the circumference of its base is 66 cm.

Solution:

To begin with we need to determine the base radius using the formula for circular perimeter (circumference).

P = 2 · π ·r

r = P /(2 · π) = 66 / (2 · π) = 10.50 cm

Now we will find the height of the cylinder using the formula for surface area of a cylinder.

SA = P · h

h = SA / P = 2640 / 66 = 40 cm

The volume of the cylinder is therefore:

V = π· r2· h

V = π· 10.502· 40

Answer:

Area=76.8

Perimeter=49.6

Answer:

A sample size of 392 is required.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

18% of students struggle in their classes because they don't spend more than 8 hours studying independently outside of a 4-unit class.

This means that [tex]\pi = 0.18[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

You would like to be 99% confident that your estimate is within 5% of the true population proportion. How large of a sample size is required?

A sample size of n is required.

n is found when M = 0.05. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.05 = 2.575\sqrt{\frac{0.18*0.82}{n}}[/tex]

[tex]0.05\sqrt{n} = 2.575\sqrt{0.18*0.82}[/tex]

[tex]\sqrt{n} = \frac{2.575\sqrt{0.18*0.82}}{0.05}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.575\sqrt{0.18*0.82}}{0.05})^2[/tex]

[tex]n = 391.5[/tex]

Rounding up:

A sample size of 392 is required.

Product – Attributes of an organization or offering within this segment include delivery system design, technology, quality, services provided and their availability.

Price – This silo of the marketing mix includes costs to users/supporters, payment periods, arrangements and terms. Note: Some have also argued “costs” are more than dollars … a full cost analysis should include emotional (for those seeking greater purpose, advancements, victory), sacrificial (for people giving time, energy, focus) and relational (what does one’s association with an organization do for their relationships … will people think more or less of them).

Place – An often-overlooked part of the marketing mix, this “P” covers strategy and executional elements surrounding service distribution channels, coverage, locations, logistics and e-services.

Promotion – Likely the most known aspect of the marketing mix, this piece considers strategies and tactics related to advertising, logo/identity and promotions. But it also covers development/fundraising, communications, events and public relations as they are all tools to be considered and deployed as part of the greater marketing and branding strategy.

Answer:

The median, mean, and mode of the data set are 5, 4.8, and both 4 and 5 respectively.

Step-by-step explanation:

To find the median of a data set, line up all values from greatest to least and find the number in the center. For example, in the set 1; 2; and 3, 2 would be the median. In this case, the order would be 2, 4, 4, 4, 5, 5, 5, 6, 6, 7. The two numbers in the middle are 5 and 5, their average is 5, so that would be the median. The mean of a data set is the average of all data values in a set. In this case, there are 10 data values, and their total sum is 48, so the mean of this data set is 4.8. The mode of a data set is the value that occurs the most in a set. In this case, 2 occurs once, 4 occurs three times, 5 occurs three times, 6 occurs twice, and 7 occurs once, so the mode of this data set is both 4 and 5.
