The domain and range of the graph above in interval notation include the following:

Domain = [-6, 3]

Range = [-3, 3]

In Mathematics and Geometry, a domain refers to the set of all real numbers (x-values) for which a particular function (equation) is defined.

In Mathematics and Geometry, the horizontal portion of any graph is used to represent all domain values and they are both read and written from smaller to larger numerical values, which simply means from the left of any graph to the right.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain and range:

Domain = [-6, 3] or -6 ≤ x < 3.

Range = [-3, 3] or -3 < y < 3

Based on the properties of continuous random variables we can say that the density curve of the probability distribution is skewed.

∑ P(X) = 1

P(x = 2) = 1 - 0.1 - 0.1 - 0.1 - 0.6 = 0.1

P(x ≥ 3) = P(x = 3) + P(x = 4) = 0.1 + 0.6 = 0.7

P(x < 3) = P(x = 0) + P(x = 1) + P(x = 2) = 0.1 + 0.1 + 0.1 = 0.3

The probability distribution table :

x P(x) x · P(x)  x² · P(x)

In probability theory and statistics, a probability distribution is the mathematical function that calculates the possibility of a range of potential experiment and it's results. It is only a mathematical explanation of a random phenomenon in the only terms of its sample space and event probability (subsets of the sample space).

To create probability distributions for the specific situation of random variables, it is common to distinguish between discrete and fully continuous random variables (so that the sample space can be viewed as a numeric set).

The value of x in the polygon will be 13.25 degrees.

The value of x is 10.

We can find the value of x by plugging in the number of sides of the regular polygon into the formula x = (n-2)*15° - 1.

The sum of the interior angles of a regular polygon with n sides is (n-2) x 180 degrees.

Sum of angles = (24-2) x 180 = 22 x 180 = 3960 degrees

Since all the angles in a regular polygon are congruent, we can divide the sum of the angles by the number of angles to find the measure of one angle:

Measure of one angle = 3960/24 = 165 degrees

165 = 12x + 6

159 = 12x

x = 13.25

Therefore, the value of x is 13.25 degrees.

Each of the triangles in our decomposition has one angle equal to (17x+2)°, so the sum of all the angles in the triangles is 43 × (17x+2)° = 731x+86°.

Therefore, we have:

731x+86° = 7380°

Solving for x, we get:

731x = 7294°

x = 10

Therefore, the value of x is 10.

The equation that can be used to find the value of x is:

(9x+48)° + (15x-24)° = (n-2)*180°

24x + 24 = (n-2)*180°

Dividing both sides by 24, we get:

x + 1 = (n-2)*15°

Subtracting 1 from both sides, we get:

x = (n-2)*15° - 1

Answer:10

Step-by-step explanation:

The fraction that represents the remaining area which the farmer still need to plough would be = 5/12.

The total area of the land that is owned by the farmer = 1

The farmer ploughed a fraction of the land = 1/3

The remaining part of the land = 1-⅓ = ⅔

The farmer ploughed 3/8 of the remaining land

= 3/8×2/3

= 1/4

To calculate the remaining land;

= 1/3 +1/4 - X = 1

= 7/12- X = 1

x= 1-7/12

X= 5/12

To reflect the function f(x) = 7^x about the x-axis, we need to negate the function, or multiply it by -1. This gives us:

g(x) = -7^x

This new function g(x) is the reflection of the original function f(x) about the x-axis. The graph of g(x) will be the same as the graph of f(x), but flipped upside down.

To reflect the function f(x) = 7^x about the y-axis, we need to replace x with -x in the function. This gives us:

h(x) = 7^(-x)

This new function h(x) is the reflection of the original function f(x) about the y-axis. The graph of h(x) will be the same as the graph of f(x), but flipped horizontally.

just subtract 21 from each number

Answer:

C - {873, 894, 915, 936, …}

Step-by-step explanation:

Difference means subtraction. So, subtract -21 from the number to get your next value.

1245 - (-21) = 1266 So, A is not the answer

32 - (-21) = 53 So, B is not the answer.

873 - (-21) = 894 So, C is the answer.

1563 - (-21) = 1584 So, D is not the answer.

To double check, subtract -21 from the other numbers too.

873 - (-21) = 894

894 - (-21) = 915

915 - (-21) = 936

and so on...

This matches up with the list of numbers on option C so it it correct.

Step-by-step explanation:

The slope-intercept form of the function described by this table is y = x + 1

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

x   y

0   1

From the above table of values, we can see that

The difference between the x and the y value is 1

Mathematicallly, this can be represeted as

y - x = 1

Add x to both sides

y = x + 1

The above equation is in the slope intercept form, y = mx + c

Hence, the equation is y = x + 1

Answer: 3 inches

Explanation:

Through trial and error you can say something like

1^3 = 1*1*1 = 1

2^3 = 2*2*2 = 8

3^3 = 3*3*3 = 27

We stop here since we got a volume of 27

Or you could apply the cube root to 27 to get the answer we are after

\(\sqrt[3]{27} = 27^{1/3} = 3\)

Answer:

A rational number is a number which can be written in form of p/q where p, q ∊ Z and q ≠ 0.

So, 0 can be written as 0/1, 0/2,... and so on in the form of p/q and 4 as 4/1. So 0 and 4 both are rational numbers.

a) A negative number on the x-axis (-a, b) would move in the left direction by one unit.

To find out why, check point (0, b) on the y-axis and point (-a, b) on the x-axis.

The distance between these two points is a unit, meaning that the point (-a, b) is one unit to the left of the point (0, b).

b) A positive number on the x-axis (+a, b) would move in the right direction by a unit.

Again, let's look at the point (0, b) on the y-axis and the point (+a, b) on the x-axis.

The distance between the two points is also one unit, which means the point (+a, b) is one unit to the right of the point (0, b).

c) A negative number on the y-axis (a, -b) would move in the downward direction by b units.

Assume that point (a, 0) is on the x-axis and point (a, -b) is on the y-axis. The distance between them is b units, which means that the point (a, -b) is b units below the point (a, 0).

d) A positive number on the y-axis (a, +b) would move in the upward direction by b units.

Also, check the point (a, 0) on the x-axis and point (a, +b) on the y-axis. The distance between these two points is b units, which means that the point (a, +b) is b units above the point (a, 0).

A number is a mathematical term used to show the quantity or value of a thing. It can be depicted using numerals, symbols, or words.

The mean of the areas of the shapes is 107.47

The triangle:

The area is calculated as

Area  = 0.5bh

So, we have

Area = 0.5 * 8 * 12

Evaluate

Area = 48

The parallelogram:

The area is calculated as

Area  = bh

Substitute the known values in the above equation, so, we have the following representation

Area = 13 * 19

Area = 247

The rectangle:

The area is calculated as

Area  = bh

So, we have

Area = 8.1 * 3.5

Area = 28.35

The polygon:

The area is calculated as

Area  = (n/2) * L * R

This gives

Area = (5/2) * 4 * 2.5

Area = 25

The trapezoid:

The area is calculated as

Area  = (1/2) * (sum of parallel sides) * height

So, we have

Area = (1/2) * (18 + 24) * 9

Area = 189

The mean is then calculated as

Mean = (48 + 247 + 28.35 + 25 + 189)/5

Mean = 107.47

Hence, the mean area is 107.47

D. The typical value is greater in set A. The spread is greater in set B.​

Step-by-step explanation:

     The typical value is greater in set A.

[] We can see that the red arrow already shows this, but the average (add up all the numbers and divide by number or numbers) in set A is greater than in set B as 7 > 6.

     The spread is greater in set B.​

[] The spread can also be thought of as the range (largest number - smallest number) so the spread is greater than B since 7 > 3.
