# How do you find an ordered pair when given only the data point?

A point, in two dimensional space, is defined as an ordered pair.

### Given a set of data how do you determine the decimal equivalent of specific data related to the whole?

I'm not sure if I totally understand your question, but this is how I see it. It is probably easiest to give an example. Consider the data set: 1, 3, 3, 4, 6, 8, 8, 9. Find the sum of the data: 42 Then if you want to know the decimal equivalent of a specific data point, you divide that amount by the sum. eg. Take the data point 3. Then 3รท42= 0.0714 (to 4…

### What is the range of the given data set -4 -3 -1 -1 0 1?

To find the range of a data set, you first need to order the data from smallest to largest. In this case, the data is already ordered in such a way. The next step is to take the least (-4) and greatest (1) numbers, and subtract the least from the greatest. In this case, we'd do 1-(-4) which equals 5. Thus the range of the data set in the question is 5.

### When do you use mean median and mode?

You use mean when you want to find the average of data. You use median to find the middle of a piece of data, ordered from least to greatest. If there is 2 medians, then find the average of those 2 numbers. You use mode when you are trying to figure out the most common piece of data. There can be more than 1 mode.

### What is directed data mining and undirected data mining?

In directed data mining, you are trying to predict a particular data point - the sales price of a house given information about other houses for sale in the neighborhood, for example. In undirected data mining, you are trying to create groups of data, or find patterns in existing data - creating the "Soccer Mom" demographic group, for example. In effect, every U.S. census is data mining, as the government looks to gather data about…

### How do you find an exact data point on an Excel graph?

Excel 2007 does not have this capability. Excel 2003 can do this as described in the related link. The idea is to draw your graph, then overlay a non-related point on the graph. When you drag the non-related point to the location on the graph where you want to identify a data point, you will see the underlying cell reference change to the location of your selected data point.

### How do you find the mean of the data?

Th find the mean of a data set, you add up all the values in the data set and divide this sum by the number of data values. For example, the mean for the data set 2, 5, 6, and 7 is given as 2 plus 5 plus 6 plus 7, which is 20. You divide this sum by number of values in the data set, which is 4 to get 5 as the mean.

### How to Derive the formula of distance between a point and a line?

You must first write an equation for the line through the point perpendicular to the line. Then, find the intersection between the two lines. Lastly, use this point and the distance formula to find the length of the perpendicular segment connecting the given point and the original line. That will lead to the following formula, d = |AX1+BY1- C|/(sqrt(A2+B2)), Where A, B and C represent the coefficients of the given line in standard form and…

### What is the ordered pair to 2x-5y equals -1?

The equation 2x-5y=-1 has a graph that is a line. Every point on that line is an ordered pair that is a solution to the equation. So pick any real number x and plug it in. You will find a y and that pair (x,y) is an ordered pair that is a solution to this equation. For example, let x=0 Then we have -5y=-1so y=1/5 The ordered pair (0, 1/5) is a point on the…

### What are the steps in calculating the quartile of group data?

Re-arrange the data in increasing order. If there are n data points, calculate (n+1)/4. Find the data point in position (n+1)/4, using interpolation if required. This is the LOWER QUARTILE. Find the data point in position 3*(n+1)/4, using interpolation if required. This is the UPPER QUARTILE. In n is large (>30, say), don't bother to add 1: just work with the observations in the n/4th and 3n/4th positions.

### How do you differentiate and find the tangent?

When you differentiate a function, you find the slope of the function. The slope is also known as the tangent. The slope of a line, given one point, and a second point relative to the first point, but with x different, is given as delta y over delta x. Differentiation is simply taking the limit of the slope, i.e. where delta x approaches zero.

### Mode of ungrouped data with example?

*Ungrouped Data* Mode of ungrouped data: An observation occurring most frequently in the data is called mode of the data. It is denoted by Z. For Example: Find the median of the following observations 4,6,8,6,7,8,8 Sol: In the given data, the observation 8 occurs maximum number of times (3) \ Mode (Z) = 8

### How do find the interquartile range in your data?

Arrange the data in increasing order and count the number of data points = N. Find the integer K = N/2 or (N+1)/2. The Kth number in the ordered set is the median. Now consider only the numbers from the smallest to the median and find the median of this subset. This is the lower quartile = Q1. Then consider only the numbers from the original median to the largest. Find the median of this…

### Find equation perpendicular to given line contain given point?

If you know the slope of the line that your equation is perpendicular too, you find the negative reciprocal of it and use it as the slope for the line. (negative reciprocal = flip the slope over and change its sign. Ex: a slope of 2 has a negative reciprocal of -1/2. ) Then you use the given point, and put your equation in point-slope form. The general equation for point slope form is Y-y1=m(x-x1)…
