Answer:
Step-by-step explanation
subtract 8 from both sides
8-2x-8=-4x+4-8
simplify
-2x=-4x-4
add 4x to both sides
-2x+4x=-4x-4+4x
Simplify
2x=-4
divide both sides by 2
2x/2=4/2
simplify
x=-2

Answer:
83
Step-by-step explanation:
Add the numbers together
So he started with 3/4 lb and ended up with 2/3 of that so 2/3 of 3/4 'of' can be roughly translated as multiply so 2/3 times 3/4 =6/12=1/2 lb left or you know that there are 3 out of 4 parts pound left so 2 out of 3 parts of nuts is = 2/4 or 1/2 lb
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)
Step-by-step explanation:
Hope this helped!
