Step-by-step explanation:
2(13x – 7). 11.
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:
n=-2
Step-by-step explanation:
add 10 to both sides
-12 + 10 = -2
ANSWER
See attachment.
EXPLANATION
The given inequality is

Divide both sides by 3 to get,


Because the inequality involves '<' we use a hollow circle at 2⅔.
