Which numbers 1-10 have straight line segments?
11
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.
How do you solve a linear inequalities?
to solve a linear in equality you have to write it out on a graph if the line or shape is made ou of strate lines its linear
Which digits are made up of only line segments?
2 4 3 5 7

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 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 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 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
How is a triangle different from a circle?
A triangle is made from 3 joined line segments whereas a circle has no line segments around its circumference
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.
