First you would have use the distributive property to make this an easier problem.So take 3 times k (if the variable has no number just add a one) and 3 times -6 to get the problem of 3k-18=15. Now you would add 18 to -18 and get 0 and do it on the 15. 15+18=33,now you have 3k=33.now you divide 3/3 and get 1 and divide 33 by 3 to get 11.
Answer is k=11

1. Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1,

zzz [600]

Answer:

Step-by-step explanation:

Given that Miguel is playing a game

The box contains 4 chips, 2 with number 1, and other two differntly numbered as 3 and 5.

OUt of these 4, 2 chips are drawn

P(drawing same number) = 2C2/4C2 = $\frac{1}{6}$

Prob (drawing differnt numbers) = 1-1/6 = $\frac{5}{6}$

Hence prob of winning 2 dollars = $\frac{1}{6}$

Prob of losing 1 dollar = $\frac{5}{6}$

b) Expected value = sum of prob x amount won

= $\frac{1}{6}2+\frac{5}{6}(-1)=-\frac{1}{2}$

c) Miguel can expect to lose 1/2 dollars for every game he plays

d) If it is to be a fair game expected value =0

i.e. let the amount assigned be s

Then $\frac{1}{6}s-\frac{5}{6}=0\\s=5$

Round to the nearest whole number 8 5/6

Aleks04 [339]

The rule for rounding is that if the fraction is less than 1/2, we round down; and if the fraction is more than 1/2, we round up.

Because 5/6 is a greater fraction than 1/2, we must round the existing whole number (8), up.

8 5/6 rounded to the nearest whole number is 9.
