The 3rd option is correct
Let a = any number
So, 1 times a = a.
In other words, any number times 1 = any number.
Two samples:
1. 45 x 1 = 45
2. -567 x 1 = -567
Understand?
It would be x+3y=15. Best of luck
Answer:
Don't accept A-G
Accept only A-E
Step-by-step explanation:
The company would those projects with a return of return equal to or higher than its cost of capital of 10.45%
Project A with a 12% return is acceptable.
Project B with a 11.5% rate of return is also acceptable
Project C has a rate of return of 11.2% , hence acceptable.
Project D has 11% rate of return and it is therefore acceptable.
Project E has 10.7% return rate and it is acceptable.
Project F has a lower rate of return of 10.3%, hence rejected, as well as projects G
Given that Erica and AAron,are using lottery system to decide who will wash dishes every night.
They put some red and blue power chips and draw each one. If same colour, Aaron will wash and if not same colours Erica will wash
If the game is to be fair, then both should have equal chances of opportunity for washing.
i.e. Probability for Erica washing = Prob of Aaron washing
i.e. P(different chips) = P(same colour chips)
Say there are m red colours and n blue colours.
Both are drawing at the same time.
Hence Prob (getting same colour) = (mC2+nC2)/(m+n)C2
Probfor different colour = mC1+nC1/(m+n)C2
The two would be equal is mC2 +nC2 = m+n
This is possible if mC2 =m and nC2 = n.
Or m = 2+1 =3 and n =3
That for a fair game we must have both colours to be 3.
