Hi I have been trying to figure out how this method works.
Searched the forum but got no results. Have attached an example I am trying to do. If someone could show me it would be great.
Or even show me a similar example worked out.
Thanks in advance
Hi I assume it would be 12. 2 x 6?
I have an answer for this question now. I just took the mean per hour and for the last 3 hours took the mean to be 7 and I got 53. It just seams too easy. Its the last question on a problem sheet and the first 5 were much more difficult and more involved...
A store opens at 8 in the morning. from 8 until 10 customers arrive at poisson rate 6 per hour. Between 10 and 12 they arrive at a poisson rate of 10 per hour. From 12 to 2, the store closes for lunch, Finally from 2 to 5 the arrival rate drops linearly from 10 per hour at 2 to four per hour at...
Not really sorry. Both are subgroups of G yes?
If I let H = the normalizer of P
Can I say P is normal in H and that as all sylow subgroups are conjugate H contains no other sylow subgroups then if N(N(P)) moves P somewhere else then there would be 2 P sylow subgroups in H?
Note: Havent been...
Im trying to prove N(N(P)) = N(P)
So N(P) = set oh h where h^-1Ph = p
Then N(N(P)) = k where k^-1hk = h
the fact that p is a p sylow subgroup gives me what information? I am unsure.
Thanks in advance!
I have a scatterplot X is just 30 given values. Y is 2*X + eps, where eps is a random figure. The Plot is Y vs X
I am asked to fit 2 lines
Y= ax +b by least squared method
and
X = cy +d
Similarly
I do not know which command to use on minitab. Is this just standard regression? if so how do...
Question: Attached.
Attempt.
I know I have to find P1 and p2 depending on x and L to satisfy
ax^2 + bxy + cy^2 + dx + ex + f =0
I have tried looking at the ladder when resting on axis to get a better picture but cannot see where to go next.
Ok so the only possible roots are 1 2 3 4 or 5 is this correct? Thanks so much for your reply! i have an exam is a few hours with this on it!
Edit: or is +-1 the only possible roots? Thanks again
F= x^3 + 2x + 1 irreducable in Z5 (Z subscript 5)
i have tried EC looking at F(x+1) which doesn't work for me. Cant think of what else to try.
Help much appreciated. Need to know this for an exam later! ahhh
Yeah i think that's what i was trying to do. Have to do this in an exam later. But We haven't covered minimal polynomials yet so he probably wants a different method. Could you point me in the right direction?
Over Q tho are +-5 +-1 The only possible roots of x^3-5?
cool thanks so much!
Let A = cuberoot(5),
and let
F = a + bA + cA in R
a; b; c in Q
Find the multiplicative inverse of the element 2 +A +A^2 in the field F.
For this I Know There is an element in the field which multiplied by this...
