me too , how was it ?I did 72, you?
I think I made a mistake in the Linear Combinations question, do you remember how you solved it? The one about plantsme too , how was it ?
yeah, the ans is 0.173 you do ( 1.5X + X) and find the new EX and VARXI think I made a mistake in the Linear Combinations question, do you remember how you solved it? The one about plants
Some people told me you have to multiply the final answer by 2, since it could be either of the plants, hopefully I did not make a mistake in another question, as threshold can be 45yeah, the ans is 0.173 you do ( 1.5X + X) and find the new EX and VARX
YesAnyone did P62?
goodYes
How did yours go?
Alhamdulilah Goodgood
How was yours?
Friends were to be divided into 3 boats so it's a selection/combination. 3 seat, 2 seat and 1 seat boats were available so 6C3*3C2*1C1=60 is the answer. Common mistake some people made was that they used permutations.A***** How did you solved the first part of the last question in P62 yesterday?
6 Friends, Boats?
I solved it incorrectly and used permutations ....Unfortunately.Friends were to be divided into 3 boats so it's a selection/combination. 3 seat, 2 seat and 1 seat boats were available so 6C3*3C2*1C1=60 is the answer. Common mistake some people made was that they used permutations.
