The amount of bidder needs to put into a kitty for the other bidders to be compensated will be $3,000.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

An object may be claimed jointly by 4 persons with the intent to split it using the sealed bid method. The winning price is $4,000.00.

The amount of bidder is given as,

⇒ $4,000 - $4,000/4

⇒ $4,000 - $1,000

⇒ $3,000

The new mean after adding a 6-inch high platform is 73 inches, while the median changes from 66 inches to 72 inches.

The mean refers to the average of a data set and is the result of the sum of the values of the data set divided by the number of items.

The median is the middle value in the data set when arranged in an ascending or descending order.

For instance, the number of the data set is 25.  The median value is the number 13, whose value is 66 inches in the old distribution or 72 inches in the new distribution.

Ratio of A to B is option c 0.86

Given,

Divorce rate in City A = 24.7%

Divorce rate in City B = 28.7%

We have to find the ratio of A to B

First we have to change the percentage to fraction form.

That is,

Divorce rate in City A = 24.7% = 24.7/100

Divorce rate in City B = 28.7% = 28.7/100

Now, ratio of A to B

(24.7/100) : (28.7/100)

Equate this into fraction form.

That is, A : B = A/B

Therefore,

(24.7/100) : (28.7/100)

= (24.7/100) / (28.7/100)

= 24.7 × 100 / 28.7 × 100

= 2470 / 2870

= 0.86 approximately.

That is the ratio of A to B is 0.86.

Ivan and Tanya share £150 in the ratio 4:1 workout. lvan gets more compared to Tanya. = $ 90

Ratio :

A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one. For example, if the number of marks scored in a test is 7 out of 10, then the ratio of marks obtained to the total number of marks is written as 7:10.

Total Ivan and Tanya share = £150

Ivan and Tanya share in the ratio of 4:1 respectively.

Let 4x be the money got by Ivan and x be the money got by Tanya.

Then, according to the question, we have

4x+x= 150

5x = 150

x= 150/5

x= 30

∴ Ivan has Money = 4x

= 4*30

= $ 120

Tanya has Money = x

= $ 30

Difference =   120-30 =  $  90

Answer: The definition/meaning of it is a theorem attributed to Pythagoras that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

Step-by-step explanation: If you need the equation solved, I can try just type under this.

In mathematics, a polynomial is a mathematical expression that is the sum of a number of terms that contain the same variable raised to different powers. These come up all the time in the study of mathematics, so it is important to be familiar with them and the different forms we can write them in.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To write a polynomial in standard form, we make sure that any like terms are combined, and then we arrange the terms so that the exponents of each term go in descending order.

For example, consider the following polynomial:

To write this polynomial in standard form, we first look for any like terms that need to be combined, where like terms are terms that have the same variable raised to the same power. We see that 8x and 2x are like terms, so we add these together to turn our polynomial into the following:

Now, we just rearrange the polynomial so that the term with the highest degree goes first, the term with the second highest degree goes second, and so on until the polynomial is arranged so that the exponents go in descending order from highest to lowest.

This gives us our polynomial in standard form.

A polynomial with 3 terms : x² + 3x³ + 27 - x

2. D: [-3,5]  and   R: [0,6]

3. D: [-2 ∝]  and   R: [-2,4]

Given:

In the first graph:

The graph's domain is its left-to-right travel distance.

Start by examining the leftmost point on this graph.

At the farthest left point, the x-value is at x=-4 Trace the graph once more until you reach the location that is the furthest to the right.

At this point, the x-value is 4. The graph is continuous from -4 to 4 since there are no breaks running from left to right.

Domain is as [-4,4]  also written as -4 ≤x≤4

The graph's range is its vertical range from down to up.

Look at the graph's lowest or most distant point. At this point, the y-value is equal to 1. Now examine the graph's top or how high it rises.

This is when x=-4 or x=4, but since we're determining the range right now, we need to take a look at the point's y-value, which is at y=3. Since the graph is continuous from top to bottom, there are no breaks in it.

Range : [1,3] also written as 1 ≤ y ≤ 3

similarly we find the rest of the domain and range of the graphs.

Hence  we don't get any line of symmetry in the graph.
