In most of the solutions they are doing like this

"They are adding the ratio terms 4 and 2 getting 6 by which 12 will be divided

Rs12/6parts=2Rs/ part .

Now they say we need to take 4 of rs2 and 2 of rs2

So the shares are rs 8 and rs 4 "

Now after seeing the soln what I feel is that I have

4 parts consists of rs 8 and 2 parts consists of rs 4 = 6 parts of Rs12

4 groups of rs 2 and 2 groups of rs 2...

Guys,can someone tell me how to find h in the last problem.

I thought 550-5%=522.5 but I don't think that is the solution.

P.S Don't ask me what the text means because even I don't know German]]>

Find the equation of the curve that passes through (0,1) using the following property:

-The area under the curve limited by the coordinate axes and the ordinate of any point is equal to the length of the curve corresponding to that region.

Differentiate each of the following with respect to x:

Answer: =3x^4-6x^3

=(3*4x^4-1)-(6*3x^3-1)

=12x^3-18x^2

Answer: =(1/3)*[3x^3-1]-2*1x^1-1 - 0

=3x^2 - 2x^0

3x^2-2

Answer: =...

Hello, I missed my last lesson about partial derivates, so I'm kinda clueless about this subject and I'm stuck with this problem. I tried solving it, but I'm sure my answer is 100% wrong. Can anyone tell me what I'm doing wrong?

1)Calculate the probability that player A wins the game.

2)Calculate the probability that player B wins the game.

The second part of the exercise is easy. It's 1-(probability of A winning the game). The problem is that I'm struggling with the first part of the exercise. First I thought I had to use a simple negative binomial...

25 families are asked about how many cars they own. Two families have 3 cars, and no families have more than three cars. The mean is 18/25 and the standard deviation is 24/25. Find the number of families who don't own any cars.

I am especially stuck on how to find this as I don't think it can be a continuous normal distribution because the possible range ends at 3 so it's not a bell curve.

If you could help me solve it and tell me how...

I have a right parallelepiped; c (side of the base) = 5 cm; B (base area) = 360 sq. cm; d (diagonal) = 200 cm.

I need to find a and b (sides of the base); S (surface area); V (volume)

All of the formula's I have aren't working because I don't know what a and b are...]]>
