The area of the shaded segement is approximately 1.68 square inches.

The complete question is:

What is the area of the shaded segment shown in O below?

Hints:

Area of shaded segment = Area of sector - Area of triangle

Area of sector = (θ/360) × πr²

Area triangle = 1/2 × b × c × sin(A)

Given that;

Area of segment = Area of sector - Area of triangle.

Area of sector = (θ/360) × πr²

Area triangle = 1/2 × b × c × sin(A)

From the diagram:

Plug the values into the above formula and simplify.

Area of segment = Area of sector - Area of triangle.

Area of segment = ( (θ/360) × πr² ) - ( 1/2 × b × c × sin(A) )

Area of segment = ( (30/360) × 3.14 × 12² ) - ( 1/2 × 12 × 12 × sin(30) )

Simplify

Area of segment = 37.68 - 36

Area of segment = 1.68 in²

Therefore, the area of the segment is 1.68 in².

Answer:

C is the formula you should use and the rest of the answers are below

Step-by-step explanation:

Hence, the formulae to calculate the variance are -

\(\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}\)     for a complete population and \(s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}\)  for a sample population.

We have Variance.

We have to specify the formula of variance.

Variance is a measure of dispersion that takes into account the spread of all data points in a data set.

According to the question, the following formulae for variance are used according to the need.

For a Complete Population divide by the size n -

\(\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}\)

For a Sample Population divide by the sample size minus 1

\(s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}\)

Hence, the the formulae to calculate the variance are -

\(\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}\)     for a complete population and \(s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}\)  for a sample population.

The given statement "descriptive statistics uses the data to make inferences and predictions about a population based on a sample of data taken from the population in question" is FALSE.

How is this false?

Descriptive statistics is a branch of statistics that studies and summarizes a set of data's main features. It aids in the interpretation of data and drawing conclusions about the population based on sample data. Descriptive statistics are used to provide a quick summary of the data set's key characteristics.

An inference is a statistical method of estimating the characteristics of a population based on a sample's data. It is a method of predicting data in a population based on the observations made in a sample. The primary goal of inferential statistics is to make predictions about a population based on data from a sample of that population.

Predictions are projections or guesses about what might occur in the future. When used in statistics, prediction refers to the use of current data to estimate what might occur later. A statistical model is usually used to make a prediction.

A population is the entire collection of items or individuals about which you want to learn in statistics. A population is made up of all of the objects or people who possess the qualities that the researcher is interested in researching.

A sample is a subset of a population that is used to collect data and conduct statistical analyses. The sample size is typically less than the population size, and data collected from a sample is used to make inferences about the population as a whole.

P = 90 is the solution for the given equation.

Given: Qd=95−4

PQs=5+P

To find Qd if P=5:

Put P = 5 in the equation

Qd=95−4P

Qd = 95 - 4 x 5

Qd = 75

So, Qd = 75.

To find P if Qs = 20:

Put Qs = 20 in the equation

Qs = 5 + PP

= Qs - 5P

= 20 - 5P

= 15

So, P = 15.

To solve Qd=Qs, substitute Qd and Qs with their respective values.

Qd = Qs

95 - 4P = 5 + P

Subtract P from both sides.

95 - 4P - P = 5

Add 4P to both sides.

95 - P = 5

Subtract 95 from both sides.

- P = - 90

Divide both sides by - 1.

P = 90

Thus, P = 90 is the solution for the given equation.

The laboratory used 30 water samples to determine if there is a difference in average discrepancy reading between the three devices. The F-test was used to determine if there is a difference in average discrepancy reading between the three devices. The p-value of the F-test is 0.977, which is greater than the significance level of 0.05. Therefore, we cannot reject the null hypothesis that there is no difference in average discrepancy reading between the three devices.

The F-test is a statistical test that is used to compare the variances of two or more groups. The F-statistic is calculated by dividing the variance between groups by the variance within groups. The p-value of the F-test is the probability of obtaining an F-statistic that is at least as extreme as the observed F-statistic, assuming that the null hypothesis is true. In this case, the p-value of the F-test is 0.977, which is greater than the significance level of 0.05.

Answer:

First rememeber that if we have a function like:

g(x) = x^n

then:

dg(x)/dx = g'(x) = n*x^(n - 1)

And also if we have:

g(x) = f(x) + h(x)

then:

dg(x)/dx = g'(x) = f'(x) + h'(x)

1) We have the function f(x) = (x + 1)^2

We can rewrite this as:

f(x) = x^2 + 2*x + 1

Using both things written above, we know that:

f'(x) = 2*x + 1*2 = 2*x + 2

And we want to find f'(-2), so we only need to evaluate the above function in x = -2, this is:

f'(-2) = 2*-2 + 2 = -4 + 2 = -2

f'(-2) = -2

b) I suppose that this refers to the inverse function of f(x)

An inverse function is such that:

g( f(x)) = x

f( g(x)) = x

For f(x) = (x + 1)^2

The inverse will be something that first cancels that square, and then subtracts 1.

Then:

g(x) = √x - 1

if we evaluate this in f(x) we get:

g( f(x)) = √(f(x)) - 1 = √(x + 1)^2 - 1 = (x + 1) - 1 = x

Then the inverse function of f(x) is:

g(x) = √x - 1

This can also be written as:

g(x) = x^(1/2) - 1

Then the derivative of this will be:

g'(x) = (1/2)*x^(1/2 - 1) = (1/2)*x^(-1/2) = (1/2)*(1/√x)

Answer:

I believe that the answer is

Galina was correct when she said: there are 2 possible outcomes.

Elroy was correct when he said: multiply the 10 outcomes

Step-by-step explanation:

I looked this up and found that when you flip a coin 10 times you get 2^10 = 1024 but including other possibilities there are only 1000 combinations. Meaning that there are 2 possible outcomes for every coin flip and in order to find those combinations you have to multiply 2 to itself for however many times you were to flip a coin.

For Example: Flip a coin 3 times there are 2 possibilities for every time you flip it. So the answer would be 2*2*2=8 combinations.

I hope this helps. :)

The answer is correct that

Galina was correct when she said: there are 2 possible outcomes.

Elroy was correct when he said: multiply the 10 outcomes by 1/2

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.

As the coin is flipped 10 times and there are to possible outcomes of coin head and tail.

So, \(2^{10}\) = 1024

In order to find the combination we have to multiply the number 2 to the number itself or raise the power of 2 to the number of times we have flipped the coin.

Let us take a case,

If we have flipped a coin 5 times and there are only two possibilities.

The answer will be=  \(2^{5} or 2*2*2*2*2*2\) = 32 combination.

The answer is (a) \($-\frac{9}{2}$\).

To find the area of the bounded region determined by the curves \($x^2=8y\)and x + 4y - 4 = 0, we first need to find the intersection points of the two curves.

From the equation \($x^2=8y$\), we get \($y=\frac{x^2}{8}$\) Substituting this in the equation x + 4y - 4 = 0, we get \($x+4\left(\frac{x^2}{8}\right)-4=0$\), which simplifies to \($x^2+8x-32=0$\). Solving for x, we get \($x=-4\pm 4\sqrt{3}$\).

Since the parabola \($x^2=8y$\) opens upwards, the area of the bounded region can be calculated as follows:

\(Area }=\int_{-4-4 \sqrt{3}}^{4 \sqrt{2}} \int_{\frac{x^2}{8}}^{(4-x) / 4} d y d x\)

Integrating with respect to y first, we get:

\(\text { Area }=\int_{-4-4 \sqrt{3}}^{4 \sqrt{2}}\left(\frac{4-x}{4}-\frac{x^2}{8}\right) d x\)

Simplifying and evaluating the integral, we get:

\(\text { Area }=\frac{9}{2}+\frac{16 \sqrt{3}}{3}-2 \sqrt{2}\)

Therefore, the answer is (a)\($-\frac{9}{2}$\).

Distance divided by speed equals time. Distance is calculated by subtracting the planets' distances.

The length of the line connecting two points is the distance between them. If the two points are on the same horizontal or vertical line, the distance can be calculated by subtracting the non-identical coordinates.

Distance = speed × time is the formula.

Therefore,

1. Assume that the sun and both planets are in line and that they are on the same side of the sun.

from the sun: Jupiter is 778,300,000

from the sun, Venus is 108,200,000

778,300,000 - 108,200,000 = 670,100,000

It would have to travel 670,100,000/6.701*10 with 8 square kilometers.

2. The three planets that are nearest to the sun are Mercury, Venus, and Earth.

Mercury's distance from the sun is 57,909,000 km.

Venus's distance from the sun is 108,200,000 km.

Earth's distance from the sun is 149,600,000 km.

combined distance between Mercury, Venus, and Earth

57,909,000+108,200,000+149,600,000 = 315,709,000

Because 315,709,000 km is less than 4,503,443,661 km, the distance from the sun to Neptune is less  than the sum of the distances from the sun.

3. Assume that every planet is on the same side of the sun and is in alignment with it.

Earth is equal to Earth at ten solar distances is 149,600,000 km *10.

New distance to Earth = 1,496,000,000km

Earth would be closest to Saturn at its distance from the sun is

1,496,000,000 -  1,296,000,000 =67,000,000

and the two would be 67,000,000 km apart.

4. Notation used in science: with a 7 square kilometer. The space shuttle moves at around 28,000 km/h.

3600 in. is equal to 25 square feet, calculated using two unit multipliers.

To convert 3600 in. to square feet, there are two unit multipliers we can use: 1 ft/12 in and (1 ft/12 in)^2. Here's how to perform the conversion:

Multiply 3600 in. by 1 ft/12 in (the first multiplier) to convert inches to feet:

3600 in. × (1 ft/12 in) = 300 ft

Multiply 300 ft by (1 ft/12 in)^2 (the second multiplier) to convert square feet back to square inches:

300 ft × (1 ft/12 in)^2 = 3600 sq in.

Since you initially had 3600 sq in, which is equivalent to 25 sq ft (because 1 sq ft = 144 sq in), your final answer is:

3600 in. = 25 sq ft

Therefore, 3600 in. is equal to 25 square feet.
