We are asked to simplify the expression
.

That's exactly what we need to do - combine like terms.
So, we subtract:

Which gives us:

Hope it helps you out! :D

Answer:
1/5, 2/15
Step-by-step explanation:
All the probabilities are the Observed Frequencies/Total Rolls = Observed Frequencies/60
That means A is 12/60 = 1/5
That also means B is 8/60 = 2/15
Answer:
its b
Step-by-step explanation:
it just is trust me.....
T = 5 a
i = 4% aa
j = 1200
c = ...
j = cit/100
c = 100j / it
c = 100*1200 / 4*5
c = 120000 / 20
c = 12000/2
c = 6000
montante
M = c+j
M = 6000+1200
M = 7200
I think $43.57 Bc 41.90 times .04 is 16.76 then move the decimal, and add 41.90+1.67=43.57
