Need help in math problem
People like me loveee long cuts :3 First find the common ratio. 40:4:15 X:5:6 40(1:0.1:0.375) X:5:6 Now equate the second ratio to find x 5/x = 0.1 6/x = 0.375 You will get x = 50 and x = 16 Find the commonly shared value of x 50/16 = 3.125 Multiply by 40 to find the no. of men... -

Mathematics: Post your doubts here!
dx/dt = 1/x - x/4 Take L.C.M dx/dt = (4 - x^2)/4x Cross multiply dx*4x = 4dt - x^2dt dx*4x = dt(4-x^2) (dx*4x)/(4-x^2) = dt Switch sides and integrate. t = -2ln(4-x^2) + c t = o x = 1 >> 0=-2ln(4-1) + c 0 = -2ln3 c = 2ln3 Substitute. t = -2ln(4-x^2) + 2ln3 t - 2ln3 = -2ln(4-x^2) -t + 2ln3 =... -

Mass = 1100 Fd = 1800 Fr = 700N Distance = x Speed = v i) K.E = 1/2(1100)v^2 = 550v^2 P.E = (1100)(10)(160) = 1760000 Now we have to find it in terms of x which is distance. So it will become 1760000/1760 = 1000x kv^2 = x 1800x = 700x+ 550v^2+ 1000x ^This is the WD equation. I just... -

Sorry for the late reply. My internet loses it sometimes. No wonder when it might lose it next :mad: So. You have Ways of choosing exactly one tenor. ANY of the remaining for the other two people 3C1*17C2 = 408 You did 3C1 * 13C2. Why 13? total people are 20. You have to choose 1 from 3 and... -

Okay I tried Note: 3 are chosen from a total of 20 so your total is 20C3 = 1140(useful to find probability) a) 3C3*17C0 = 1 For probability, divide by total 1/1140 = 0.00087 b) List all the possibilities. Remember 3 are chosen and exactly 1 bass is chosen…. ● 4C1*3C2 = 12 ● 4C1*6C2 = 60... -
