Vinay made a password that consists of 3 digits. None of the digits are the same. How many possible passwords did vinay choose from?
Assuming a 3-digit password can begin with a zero, the answer is 720.
How many 3-digit numbers can made using the digits 2 3 4?
If you can repeat a digit, there are 27. If you can't repeat a digit, there are only 6.
How many 6 digit numbers can be formed with 4 different digits?
The question can be re-stated as asking for the total number of permutations that can be derived from the following two groups of digits: AAABCD and AABBCD, where A, B, C and D are different. The number of ways of choosing the digit A, to be used three times, out of the ten digits {0, 1, 2, ... 9} is 10. Having done that, the number of ways of selecting 3 from the remaining 9 digits is 9C3 = (9*8*7)/(3*2*1) = 84. Thus there are 10*84 = 840 combinations of the form AAABCD. You now need all the distinct permutations of these 6 digits. The total number of permutations of 6 digits is 6! but because 3 of the digits are the same, these permutations are not all distinct. In fact, there are 6!/3! = 120 distinct permutations. That makes a total of 840*120 = 100800 such numbers. Next, the number of ways of choosing the digits A and B, each to be used twice, out of the ten digits {0, 1, 2, ... 9} is 10C2 = (10*9)/(2*1) = 45. Having done that, the number of ways of selecting C and D from the remaining 8 digits is 8C2 = (8*7)/(2*1) = 28. Thus there are 45*28 = 1260 combinations of the form AAABCD. You now need all the distinct permutations of these 6 digits. The total number of permutations of 6 digits is 6! but because 2 pairs of these digits are the same, these permutations are not all distinct. In fact, there are 6!/(2!*2!) = 180 distinct permutations. That makes a total of 1260*180 = 226800 such numbers. The grand total is, therefore, 100800 + 226800 = 327600 6-digit numbers made from 4 distinct digits.
What is the difference between a trend line and a line of best fit?
A trend line is graphed from a linear, exponential, logarithmic or other equation, and trys to fit the sorted data that you have. But it may or may not be correlated. The line of best fit is the trend line that best fits your data, having a high correlation. R closer to 1.
Which digits are made up of only line segments?

A closed figure made of line segments?
A polygon, if all the line segments are in the same plane.
A closed figure made up of line segments is?
A closed figure made up of line segments is called a polygon. The segments in a polygon are called sides or edges.
What digits are made up of only line segments in 2 4 3 5 7?
The way the font is, only 4 and 7 can be drawn with straight lines.
What is called a closed figure made up of three line segments is?
If the line segments are straight, then it is a triangle.
Is polygon made up of 2 line segments?
No. A polygon must have at least three line segments.
What is a shape made up of line segments?
A shape made up of line segments is a shape with straight lines, or a polygon. for example, a square has straight lines, or is made up of line segments. A circle is not in that category because it has no straight lines, they are curved.
How is a circle different from a polygon?
Polygons have sides made of line segments (straigh lines). There are no line segments in a circle.
What is a two dimensional closed shape made of line segments?
They are polygons which have 3 or more line segments
What do you called an any closed plane made of line segments?
A plane shape. There is no specia name unless all the line segments are straight.
What is a closed figure made up of line segments?
a polygon
