Step-by-step explanation:
2.65x + 2.50 = y
step by step explanation:
2.65 is how much for each mile, and the variable, x, represents the number of miles of the trip. so, we would do 2.65x to find out how much money you have to pay for the amounts of mile.
next, you would have to add the initial fee, which is 2.50. so 2.65x+2.50.
lastly, y represents the total cost of the trip. so, 2.65x + 2.50 = y

b) P(2y) = 0,329
Step-by-step explanation:
a) Attached
b) Probability of the second ball is yellow P(2y) is equal to the probability of the second ball is yellow given that the first one is black ( 0,204 ) plus the probability f the second ball is yellow given that the first one is yellow ( 0,125)
P(2y) = 0,204 + 0,125
P(2y) = 0,329
