imhist(x); where 'x' is your data or image to find histogram.
_x?That's the average.sum of all x divided by nx
x can represent anything. it depends on the equation. in maths you generally must find the value of x. eg: 8 + x = 15. In this case you must figure out what number added to 8 equals 15. Because the opposite to addition is subtraction, to find x you would do x = 15 - 8. Therefore x = 7. So x has no given value, it all depends on the equation. Hope that helped :)
The terminology "scatter diagram" is used in Microsoft Excel and it causes some confusion. The difference is in the x-axis. If my x data is 1900, 1901 2000 and my y data is 100, 300, 3000, then a line plot (in Excel) would show on the x-axis three regularly spaced marks corresponding to 1900, 1901 and 2000. However, on a scatter diagram, intervals are always numerically equal, so 1900 and 1901 are very close together. Scatter diagram, as Microsoft defines them, can show line only, lines and points or just points. It is the preferred plot for data in technical/ scientific work. Where the data is sparse and/or alternative interpretation possible, I would suggest showing both points and lines. Line graphs (again, as Microsoft defines it) can distort relationships. See related link below for some good examples.
For discrete distributions, suppose the variable X takes the specific value x with probability P(X=x) Then add together x * P(X = x) for all possible values of x. For continuous distributions, suppose the probability distribution function of the variable X is f(x). Then the mean is the integral of x*f(x) with respect to x, taken over all possible values of x.
I'm not sure how to explain it in words, so I'll give you two examples.1. Let's say we have a graph with the domain {x: -57}This means that in the graph, x has every value between -5 and 0 (exclusive), and every value over 7. So in the graph, x can not be -6, -5, 1, 2, 3, and etc.2. Another example of this is in a Venn DiagramThe union of a Venn Diagram is the addition of the 2 circles of the Venn Diagram, and subtracting their intersection.
Absolute value of x is x, if x is greater than or equal to zero, and -x if x<0.
Factor them. 2 x 3 = 6 2 x 2 x 2 x 2 = 16 2 x 19 + 38 Combine the highest amount of each factor. 2 x 2 x 2 x 2 x 3 x 19 = 912, the LCM
Common factors: 3, 5, 15. HCF: 15. To work out: Make a factor tree or ladder. (Ignore the dashes) ----45 ---/---\ --3----15 -------/---\ ------3----5 We cannot go any further as 3 & 5 are prime. Therefore 45 = 3 x 3 x 5. (same with 60) 60 = 2 x 2 x 3 x 5. The easiest way is to now make a venn diagram. Put the numbers that appear in both lists in the intersection. (3 and 5 but do not put both threes in) my venn diagram--->(3)(3, 5) (1, 2) Then, times the numbers in the intersection together... and voila! You get 15 which is the HCF! --To find the LCM, multiply all the numbers in the VENN DIAGRAM together. =] \AT
Given the following Venn diagram, choose the correct set for .
The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
It is: 2x+11 = -1 and the vaue of x works out as -6

Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM
