    Maths, Addmaths and Statistics: Post your doubts here!

    Well the 8_9 is one element. You can interchange the 8 and 9 i.e it can be 8_9 or 9_8. Now the blank between the 8 and 9 can be filled by only one number from seven so 7P1 and the remaining 2 can be arrange from 6 so it will be 6P2. Now there are 3 ways in which the 8_9 can be placed 8_9_ _...

    Maths, Addmaths and Statistics: Post your doubts here!

    Also in some questions it can ask you in how many ways can these numbers be arranged such that there is exactly one digit in between the 8 and 9. This is slightly more demanding but same thing here. To proceed you enclose the 8_9 or 9_8 inside a SINGLE square and count it as one element. But...

    Maths, Addmaths and Statistics: Post your doubts here!

    Well first thing you want to do is to put 8 and 9 adjacent. Now you are left with 3 numbers to arrange from 7. To arrange these 3 numbers it will be 7P3. Now it has not specified any order for the 8 and 9 as in whether the 8 is first or the 9 but the question has just said that they should be...

    Maths, Addmaths and Statistics: Post your doubts here!

    If x is the angle at A, you draw a quadrant, evaluate x. Then draw a line with an angle x to the horizontal. This shows the direction in which A is moving. Now using the velocity of A(which you forgot to specify) find this velocity in vector form. To do this find the horizontal displacement...

    You need to specify which one is angle x and which one is angle y. Is x the angle for A or the angle for B??

    Add. Maths modulus function range

    One more thing if you have y= |3x-2| + 4, proceed in this similar way and remember that the critical value of x in this example will be 2/3 as this is the value for which the value INSIDE the modulus is zero. Don't get confused, for this example some students get confused as they think that the...
