suppose one individual is randomly chosen. find the probability that this person has an iq greater than 95.

Answers

Answer 1

The probability that this person has an IQ greater than 95 =62.93%

What is probability?

The area of mathematics known as probability is concerned with the outcomes of random events. Probability refers to a chance or potential for something to happen. It explains the likelihood that a specific event will take place.

We frequently say things like, "It will probably rain today," "He will probably pass the test, "There is very little chance of getting a storm tonight," and "Most likely the price of onions will increase once more." We substitute the word probability for all of the words chance, doubt, maybe, likely, etc. in these sentences.

In essence, probability is the ability to forecast an outcome based on the variety and quantity of potential outcomes or the analysis of historical data.

Let X be the IQ

IQ is normally distributed with a mean of 100 and a standard deviation of 15.

a) the probability that this person has an IQ greater than 95

=62.93%

b) the probability that this person has an IQ less than 125

=4.75%

c) Sample size =500

No of people = 0.2486(500) =124.3

describe the proof princple used in a proof that shows a property of some natural number abd goes on to show that the same property holds for all natural numbers

Answers

The proof principle that you are describing is known as induction. Induction is a method of proof that is used to establish that a property holds for all natural numbers (or, more generally, for all elements of a well-ordered set).

The basic idea behind induction is as follows:

First, you start with a base case, which is a specific natural number (usually 0 or 1) for which you can directly prove that the property holds.

Next, you assume that the property holds for some natural number n. This is known as the induction hypothesis.

Using the induction hypothesis, you then prove that the property also holds for the natural number n+1. This is known as the induction step.

Since you have already established that the property holds for the base case, and you have shown that if it holds for one natural number, it must also hold for the next natural number, it follows that the property holds for all natural numbers.

Induction is a very powerful proof technique and is used extensively in mathematics to prove theorems about the properties of natural numbers and other well-ordered sets.

Answers

Risk is the potential that a chosen action may lead to an undesirable outcome.

About risk

In simple terms, the definition of risk is a condition that is uncertain, but contains an element of danger as a consequence or result of something. Once again, this something is a business, business, activity, or decision that you make.

Types of Risk

The risks themselves are divided into several types, complete with different characteristics.

1. Pure Risk 

This pure risk is certain, meaning that when the risk occurs, you will experience a loss. And vice versa, if pure risk does not occur, then you will make a profit.

2. Speculative Risk 

There are three possibilities that will happen, if you experience speculative risk, namely profits, losses, or maybe break even. What is meant by break even is the break even point.

Conditions where there are no profits or losses, so it's normal. The most obvious examples of speculative risk are the lottery, stock exchange, exchange risk, and others.

3. Particular Risk or Special Risk

Specific risks originate from individual activities, so the impact can still be estimated or anticipated at the outset because they are local in nature. For example, a turbine explosion, a shipwreck, or maybe a crash.

How to anticipate it (example for collision risk). You can take out insurance to provide guarantees or protection, both for the vehicle and for yourself.

4. Fundamental Risk 

Fundamental risks come from the surrounding environment or nature which can have quite a big impact, because humans are not able to control them.

Use the SOLVE Process to determine the missing coefficient
of a given polynomial. P(x)=x^4 - 3x^3 +ax^2 - 6x + 14

Answers

Answer:

To determine the missing coefficient "a" in the polynomial P(x) = x^4 - 3x^3 + ax^2 - 6x + 14, we can use the SOLVE process as follows:

S: Write down the given information and identify the problem.

We are given the polynomial P(x) = x^4 - 3x^3 + ax^2 - 6x + 14, and we need to find the value of the missing coefficient "a".

O: Organize the information and decide on a plan.

To find the value of "a", we can substitute specific values for x into the polynomial and solve for a.

L: Carry out the plan.

For example, let's say we substitute x = 2 into the polynomial. We get:

P(2) = 2^4 - 32^3 + a2^2 - 6*2 + 14

= 16 - 24 + 4a - 12 + 14

= -4 + 4a + 2

= 4a - 2

We are given that P(2) = 4a - 2 = 0, so 4a = 2.

Solving for a, we get:

a = 2 / 4

= 0.5

V: Check the solution.

We can check the solution by substituting 0.5 for a in the original polynomial and verifying that it gives us the correct result for P(x) when x = 2.

P(x) = x^4 - 3x^3 + 0.5x^2 - 6x + 14

Substituting x = 2 and a = 0.5, we get:

P(2) = 2^4 - 32^3 + 0.52^2 - 6*2 + 14

= 16 - 24 + 1 - 12 + 14

= 0

Since P(2) = 0, our solution appears to be correct.

Therefore, the missing coefficient "a" in the polynomial P(x) = x^4 - 3x^3 + ax^2 - 6x + 14 is 0.5.

To find the slope of a line parallel to a given line, we need to find the slope of the given line and use it as the slope of the new line. The slope of a line can be found by using the formula slope = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

To find the slope of a line parallel to the line y=-x-5, we can use the formula to find the slope of the given line. We can choose any two points on the line to use in the formula, but it is often convenient to choose two points that are easy to work with. In this case, we can choose the points (1, -1-5) and (2, -2-5) as the points to use in the formula. Plugging these values into the formula, we get slope = (-1-5 - (-2-5))/(1 - 2) = (-6 - (-7))/(-1) = 1.
Therefore, the slope of a line parallel to y=-x-5 is 1.

To find the slope of a line parallel to the line y=2x-2, we can use the formula to find the slope of the given line. We can choose any two points on the line to use in the formula, but it is often convenient to choose two points that are easy to work with. In this case, we can choose the points (1, 21-2) and (2, 22-2) as the points to use in the formula. Plugging these values into the formula, we get slope = (21-2 - 22-2)/(1 - 2) = (0 - (-2))/(-1) = 2.
Therefore, the slope of a line parallel to y=2x-2 is 2.

To find the slope of a line perpendicular to a given line, we need to find the slope of the given line and use the negative reciprocal of the slope as the slope of the new line. The negative reciprocal of a slope is calculated by taking the reciprocal of the slope (which is the inverse of the slope), and then negating the result. For example, the negative reciprocal of a slope of 2 is -1/2, and the negative reciprocal of a slope of -3 is 1/3.

To find the slope of a line perpendicular to the line y=-x-1, we can first use the formula to find the slope of the given line. We can choose any two points on the line to use in the formula, but it is often convenient to choose two points that are easy to work with. In this case, we can choose the points (1, -1-1) and (2, -2-1) as the points to use in the formula. Plugging these values into the formula, we get slope = (-1-1 - (-2-1))/(1 - 2) = (-2 - (-3))/(-1) = 1.
Therefore, the slope of the given line is 1. To find the slope of a line perpendicular to this line,

What is the domain of a radical?

Answers

If this answer helps you, brainliest is appreciated

The domain of a radical is the set of all values of the independent variable for which the radical is defined.

For example, consider the radical expression √x. This expression is defined for all nonnegative values of x, since the square root of a nonnegative number is always real. Therefore, the domain of the radical √x is the set of all nonnegative values of x:

{x | x ≥ 0}

This includes all real numbers that are greater than or equal to zero, such as 0, 1, 2, 3, and so on.

On the other hand, if we consider the radical expression √(x-2), this expression is defined for all values of x such that x-2 is nonnegative. This means that the domain of the radical √(x-2) is the set of all values of x such that x ≥ 2:

{x | x ≥ 2}

This includes all real numbers that are greater than or equal to 2, such as 2, 3, 4, 5, and so on.

In general, the domain of a radical is determined by the values of the independent variable that make the expression under the radical nonnegative. If the expression under the radical is always nonnegative, then the domain of the radical is the set of all real numbers. If the expression under the radical is not always nonnegative, then the domain of the radical is the set of all values of the independent variable that make the expression nonnegative.

Answer:

The domain of a radical is the set of all values that can be plugged into the radical without resulting in an undefined or imaginary value.For example, the domain of the square root function sqrt(x) is all non-negative real numbers, since the square root of a non-negative real number is always a real number. This means that the domain of sqrt(x) is the set of all real numbers x such that x >= 0.On the other hand, the domain of the square root function sqrt(x^2 - 4) is all real numbers except for the values x = 2 and x = -2, since the square root of a negative number is an imaginary number. This means that the domain of sqrt(x^2 - 4) is the set of all real numbers x such that x != 2 and x != -2.In general, the domain of a radical is the set of all values for which the expression inside the radical is greater than or equal to 0. This is because the radical of a negative number is an imaginary number, which is not included in the domain of the radical.

The value of [tex]r^{\prime}(t)[/tex] is [tex]\left\langle 3,4 t, 12 t^2\right\rangle[/tex].

The value of unit tangent vector T(1) is [tex]\left\langle\frac{3}{13}, \frac{4}{13}, \frac{12}{13}\right\rangle \quad[/tex]

The value of r''(t) is [tex]\langle 0,4,24 t\rangle[/tex]

The value of r'(t) × r ''(t) is [tex]\left(48 t^2\right) \vec{i}-(68 t)\vec{j}+(12)\vec{k}[/tex]

As per the data given in the question r(t) = 3t, [tex]2t^{2}[/tex], [tex]4t^{3}[/tex]

From r(t) we can find the value of [tex]r^{\prime}(t)[/tex].

For that we have to differentiate each term of r(t).

[tex]r^{\prime}(t)=\left\langle 3,4 t, 12 t^2\right\rangle[/tex]

Tangent and Normal Vectors:

The tangent and unit normal vectors are calculated from the derivatives of the parameter settings of the curve.

In particular, to determine the unit tangent vector, we have:

[tex]& \vec{T}(t)=\frac{\partial^{\prime}(t)}{\left|r^{\prime}(t)\right|} \\[/tex]

Therefore [tex]\vec{T}(1)=\frac{\partial^{\prime}(1)}{\left|\partial^{\prime}(1)\right|}[/tex]

[tex]\partial^{\prime}(1)=\langle 3,4,12\rangle \\& \therefore\left|r^{\prime}(1)\right|=\sqrt{9+16+144}\\=\sqrt{169}\\=13[/tex]

[tex]\vec{T}(1)=\frac{\langle 3,4,12\rangle}{13}[/tex]

[tex]& =\left\langle\frac{3}{13}, \frac{4}{13}, \frac{12}{13}\right\rangle[/tex]

[tex]\vec{T}(1)=\left\langle\frac{3}{13},\frac{4}{13}, \frac{12}{13}\right\rangle[/tex]

[tex]\vec{T}(1)=\left\langle\frac{3}{13}, \frac{4}{13}, \frac{12}{13}\right\rangle \quad[/tex]

Now [tex]r^{\prime}(t)=\left\langle 3,4 t, 12 t^2\right\rangle \\[/tex]

From r'(t) we can find the value of r''(t).

For that we have to differentiate each term of r'(t)

[tex]r^{\prime \prime}(t)=\langle 0,4,24 t\rangle[/tex]

Now we have to find the value of r'(t) × r ''(t).

[tex]\partial^{\prime}(t) \times \partial^{\prime \prime}(t)=\left|\begin{array}{ccc}i & j & k \\3 & 4 t & 12 t^2 \\0 & 4 & 24 t\end{array}\right|[/tex]

[tex]&=i\left(96 t^2-48 t^2\right)-j(68 t)+k(12) \\&=\left(48 t^2\right) \vec{i}-\vec{j}(68 t)+\vec{k}(12) \\[/tex]

[tex]r^{\prime}(t) \times r^{\prime \prime}(t)=\left(48 t^2\right) \vec{i}-\vec{j}(68 t)+\vec{k}(12)[/tex]

Answers

The total number of ways there are for eight blue-shirt and five red-shirt to stand in a line so that no two red-shirts stand next to each other is 609638400.

What is permutation?

A permutation of a set is, broadly speaking, a rearranging of its elements if the set is already ordered, or arranging its members into a sequence or linear order.

Given:

The eight blue-shirt and five red-shirt stands in a line,

Calculate the number of ways as shown below,

The total number of ways = Total no of permutations of blue ones × Total permutation of 9 positions, taken 5 at a time,

N = 8! × 9! / (9 - 5)!
