Answer:
40
Step-by-step explanation:
a+b=c
a=girls
b= boys
c= total
the statement tell us:
4/5 of a class is girls:
a=(4/5)*c
boys=b=8
c=a+b
so we have:
c=(4/5)*c + 8
c-(4/5)*c=8
(5c-4c)/5 = 8
c/5=8
c=8*5
c=40
total=40
When we solve for y, we want to isolate y by itself. To do so in this equation, we can divide both sides of the equation by 62...
y = 434/62 = 7
Answer:
Total possible number of outcomes = C(24,6) [24 choose 6]
=24!/(6!18!)
= 134596
Out of which there is only one winning combination.
Therefore we conclude:
P(win 20000)=1/134596
P(lose 1)=134595/134596
and hence the expected value is:
20000*(1/134596)+(-1)*(134595/134596)
=-114595/134596
=-0.8514 (rounded to four places after decimal)

A coefficient is the number attached to a variable (k). In front of k is an implied 1 because k*1=k. So the coefficient of the third terms is 1
