Answers

Answer 1

Probability of getting a marble is 0.3.

Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event. measures the chance of an event happening and is equal to the number of favorable events divided by the total number of events. The value of probability ranges between 0 and 1, where 0 denotes uncertainty and 1 denotes certainty.

Two boxes Probability of selecting either of the box = 0.5

Box A contains: 3 blue and 2 red marbles. So, probability of selecting blue marbles,

let p(B1) = [3C1/5C1 ]= 0.6*0.5 = 0.3 (As Probability of selecting box 1 is 50:50 )

Box contains : 3 blue and 5 red marbles,

let p(B2) = [3C2/5C2] = 0.6*0.5 = 0.3 ( As the probability of selecting box 2 is also 50:50 )

So, the final probability of getting a blue ball is 0.3.

question content area top part 1 express the following angular speed in radians per second. 14 revolutions per second

Answers

The angular speed of 14 revolutions per second is equal to 87.96 radians per second.

Angular speed is a measure of how fast an object is rotating or revolving around an axis. It is typically measured in units of angular displacement per unit of time, such as degrees per second, revolutions per minute (RPM), or radians per second.

To convert angular speed from revolutions per second (RPS) to radians per second (RAD/s), we can use the following formula:

Angular speed (RAD/s) = 2π x Revolutions per second (RPS)

Given that the angular speed is 14 revolutions per second, we can substitute this value into the formula:

Angular speed (RAD/s) = 2π x 14 RPS

Angular speed (RAD/s) = 87.96 RAD/s

So, 14 revolutions per second is equivalent to 87.96 radians per second.

OD) 70°

Answers

Answer: Choice B)  52 degrees

=======================================================

Explanation:

Every triangle has the rule where the inside angles add to 180.

(angle1)+(angle2)+(angle3) = 180

x + (x-4) + (x+16) = 180

3x+12 = 180

3x = 180-12

3x = 168

x = 168/3

x = 56

Then we can determine each angle.

angle1 = x = 56 degreesangle2 = x-4 = 56-4 = 52 degrees  (choice B)angle3 = x+16 = 56+16 = 72 degrees

As a check:

The order of the functions' average rates is h(x), g(x) and f(x)

How to order the functions' average rates

From the question, we have the following parameters that can be used in our computation:

The functions

The interval is given as

4 ≤ x ≤ 7

And the average rate is calculated as

Rate = (f(x₂) - f(x₁))/(x₂ - x₁)

So, we have

f(x) rate = (10 + 10)/(7 - 4) = 6.67

g(x) rate = (19 - 7)/(7 - 4) = 4

For h(x), we have

h(7) = 7^2 - 9 * 7 + 5 = -9

h(4) = 4^2 - 9 * 4 + 5 = -15

So, we have

h(x) rate = (-15 + 9)/(7 - 4) = -2

The values of m and b on the linear equation:

How to find the values of m and b?

A general linear equation can be written as in the slope-intercept form as:

y = m*x + b

Where m is the slope and b is the y-intercept.

Here we have the linear equation

2 + 3x + 5 - 2x = y

Now we want to write this in the slope-intercept form, to do so, we just need to simplify the left side, then we will get:

2 + 3x + 5 - 2x = y

(2 + 5) + (3x - 2x)  =y

A logarithm is an operation used to determine the exponent of a given base number.

What is logarithm?

A logarithm is a mathematical function that describes the relationship between the power to which a number (called the base) must be raised, and the resulting value. The logarithm of a number is the power to which the base must be raised to produce that number.

Start by moving the logarithm to the left-hand side of the equation: log(x²-15) = log(2x)

Next, use the property of logarithms that log(a/b) = log(a) - log(b) to get x²-15 = 2x

then you can simplify the equation by subtracting 2x from both sides x²-2x-15=0

then factor the equation to get (x - 5)(x + 3) = 0

Finally, use the Zero Product Property to solve for x. The solutions will be x = 5 or x = -3

[tex]\textsf{b)} \quad c^{-1}(x)=5+\sqrt{x-2},\;\; c\geq2[/tex]

[tex]\textsf{c)} \quad f^{-1}(x)=-\dfrac{2x}{3x-5}[/tex]

Step-by-step explanation:

Part a

Given function:

[tex]a(x)=-4x^2+3[/tex]

To find the inverse of the function, swap x and y:

[tex]\implies x=-4y^2+3[/tex]

Rearrange the equation to isolate y:

[tex]\implies x-3=-4y^2[/tex]

[tex]\implies y^2=-\dfrac{x-3}{4}[/tex]

[tex]\implies y^2=\dfrac{3-x}{4}[/tex]

As the domain and range of function a(x) are unrestricted, the inverse relation is a “sideways” parabola and therefore it is not a function, since it fails the vertical line test.

Part b

Given function:

[tex]c(x)=(x-5)^2+2,\;\;x\geq5[/tex]

As the domain of function c(x) is restricted to x ≥ 5, the range is also restricted.

Range: c(x) ≥ 2

To find the inverse of the function, swap x and y:

[tex]\implies x=(y-5)^2+2[/tex]

Rearrange the equation to isolate y:

[tex]\implies x-2=(y-5)^2[/tex]

[tex]\implies \pm\sqrt{x-2}=y-5[/tex]

[tex]\implies y=5\pm\sqrt{x-2}[/tex]

As the domain of function c(x) is restricted to x ≥ 5 then:

[tex]\implies y=5+\sqrt{x-2}[/tex]

Replace y with c⁻¹(x):

[tex]\implies c^{-1}(x)=5+\sqrt{x-2}[/tex]

The domain of the inverse of a function is the same as the range of the original function.  Therefore, the domain of the inverse function is restricted to x ≥ 2.

Part c

Given function:

[tex]f(x)=\dfrac{5x}{3x+2}[/tex]

To find the inverse of the function, swap x and y:

[tex]x=\dfrac{5y}{3y+2}[/tex]

Rearrange the equation to isolate y:

[tex]\implies x(3y+2)=5y[/tex]

[tex]\implies 3xy+2x=5y[/tex]

[tex]\implies 3xy-5y=-2x[/tex]

[tex]\implies y(3x-5)=-2x[/tex]

[tex]\implies y=-\dfrac{2x}{3x-5}[/tex]

Replace y with f⁻¹(x):

[tex]\implies f^{-1}(x)=-\dfrac{2x}{3x-5}[/tex]

They are employed in a wide variety of mathematical disciplines and contexts, including calculus, statistics, physics, and engineering, as well as linear algebra. Matrices are an essential tool for solving systems of linear equations and representing linear transformations since they may be added, subtracted from, and multiplied by other matrices.

The matrix multiplication of [2 1 0] and [1 -1 2 -1 -2 1 0 1 1] is:

[2 1 0] x [1 -1 2 -1 -2 1 0 1 1] = [2(1) + 1(-1) + 0(2), 2(-1) + 1(-2) + 0(1), 2(0) + 1(1) + 0(1)]

= [2 -3 1]

Therefore, the product of the two matrices is a row vector [2 -3 1], which has the dimensions 1 x 3.

If we subtract 1 from each element of this row vector, we get:

[2 -3 1] - 1 = [1 -4 0]

So, the resulting vector has the same dimensions as the original, 1 x 3.

The sum of the differences between sample observations and the sample mean is
a. Zero
b. The range
c. The mean deviation
d. The standard deviation

Answers

The sum of the differences between sample observations and the sample mean is zero.

Statistics is a science that deals with methods of collecting data, processing data, presenting data, analyzing data, drawing conclusions, and making reasonable decisions based on existing facts.

There are some terms that are frequently used in statistics:

Range is the difference between the largest and the smallest values in a data set;Mean is the average of the sample values;Mean deviation is the average deviation of the data from the mean;Variance is a measure of how far the data is spread from its average value, which is equal to the average distances of the sample observations from the sample mean;Standard deviation is a value used to determine the distribution of data in a sample and see how close the data is to the mean value. The standard deviation is equal to the square root value of the variance.

The sum of the differences between sample observations and the sample mean can be denoted as ∑(xi - mean), where n is the size of the sample and i = 1,2,3,...,n

∑(xi - mean) = ∑xi - n*mean,

                    = n*mean - n*mean

                    = 0

Thus the sum of the differences between sample observations and the sample mean is zero.

g suppose that w(t) is a real-valued signal. prove that its fourier transform magnitude is symmetric around f

Answers

Since the Fourier transform of a real value signal is the product of the even cosine transform and the odd sine transform, it is conjugate symmetric and consequently symmetric about the frequency 0.

A real-valued signal's Fourier transform is a conjugate symmetric function, which means it is symmetric about frequency 0. This is demonstrated by the fact that a real-valued signal's Fourier transform may be expressed as the product of its cosine and sine transforms:

F(w) = Fc(w) plus Fs (w)

Where the cosine and sine transforms, respectively, are denoted by Fc(w) and Fs(w). Both the sine and cosine transforms are symmetric about the frequency zero because the sine transform is an odd function and the cosine is an even function. As a result, a real-valued signal's Fourier transform also exhibits symmetry near frequency 0.

Maria will spend less than $29 on gifts. So far, she has spent $17. What are the possible additional amounts she will spend?
Use c for the additional amount (in dollars) Maria will spend.
Write your answer as an inequality solved for c.

Answers

Answer:
Maria is able to spend less than $12.
C < 12

Step-by-step explanation:

If Maria has already spent 17 dollars, that means she has 12 dollars left. C cannot be greater than 12. It has to be less.

So think of this C < $12
So if we do the total on one side and the $17 and C on the other side of inequality we get
C + 17 < 29

It cannot be equal to 29 so that's why we don't use a less than or equal to symbol.

Simplify this to get C < 12

I hope this is able to help you :D

The elements of the set A'(B∩C)is  { r, t , v, x, y, z}

How to determine the set

It is important to note that the universal set is the set containing all the elements for a given event.

From the information given, we have that;

U = {(q, r, s, t, u, v, w, x, y, z)A = {q, s, u, w, y}B = {q, s, y, z)C = {v, w, x, y, z)

The signs used to represent sets are;

∩ - Intersection of sets used to represent the common elements of two or more sets∪- Union of sets used to represent the sum of sets without repetition

To determine the set,

A'(B∩C)

A' = { r, t, v, x, z}

B∩C = { y, z}

Now, the set A'(B∩C)

A'(B∩C) = { r, t , v, x, y, z}

Hence, the set is { r, t , v, x, y, z}

Mrs. Barton should use 2 cups of peanut butter in her huge batch with 1 cup of oil.

What is fraction?

Fractions are a way of representing part of a whole. They are written as two numbers separated by a slash. The top number is called the numerator, and the bottom number is called the denominator. For example, in the fraction 1/2, 1 is the numerator and 2 is the denominator. This fraction represents one part of a total of two parts.

Mrs. Carter's famous peanut butter cookies call for 1 cup of peanut butter for every 1/2 of a cup of oil. Today, she wants to make a huge batch with 1 cup of oil.

From the above question:

1/2 cup of oil = 1 cup of peanut butter

1 cup of oil = x

Cross Multiply

1/2x = 1 × 1

x = 1 ÷ 1/2

x = 1 × 2/1

x = 2 cups of peanut butter.

Therefore, for huge batch with 1 cup of oil, she should use 2 cups of peanut butter.
