The answers in order are
Y= 10/4
Y=5/3
1/4
if 3/4 cyclists finish then that leaves 1/4 of the group that did not finish
Answer:
Y = 45*p(y) / (1 - p(y)) if I knew what p(y) is, we can find how many yellow marbles there are. p(y) = probability of choosing yellow.
Step-by-step explanation:
Total marbles = 35 + 10 + yellow
If probability of choosing yellow =p(y) = yellow/Total
p(y) = Y/(35 + 10 + Y)
Solve for Y,
p(y)*(35 + 10 + Y) = Y
45*p(y) + p(y)*Y = Y
45*p(y) = Y - p(y)*Y
Y = 45*p(y) / (1 - p(y))
Answer:
Box of Popcorn: $3.00
Drink: $2.00
Step-by-step explanation:
If we input the prices into the original problem it would be something like this, (2)3.00 + (3)2.00 = $12.00 (3+3 = 6 and 2 + 2 + 2 = 6 6+6= 12) Or 2x + 3x = $12
And you would do the same thing for the second one.
(3)3.00 + (5)2.00 = $19.00 ( 3 + 3 + 3 = 9 and 2 + 2 + 2 + 2 +2 = 10 10+9= 19) Or 3x + 5x = $19
Sorry if it's incorrect but i hope it helps!
