Do like this
(y - 1)(y² + 2y + 1)
y³ + 2y² + y - y² - 2y² - 1
y³ - 1
This is end result
Answer:
The probability is 3/95
Step-by-step explanation:
Okay this is a probability without replacement question.
Firstly we calculate the total number of coins = 7 + 9 + 4 = 20 coins
The probability that the first coin will be a dimes = number of dimes/total number of coins = 4/20 = 1/5
Now she removes a coin without replacement, if it was a dime, total number of coins becomes 19 and the total number of dimes becomes 3; Thus the probability of the second coins being a dimes = 3/19
Thus, the probability of both coins being dimes = probability of first coin being dimes * probability of second coins being dimes
= 1/5 * 3/19 = 3/95
Answer: i think it’s C
Step-by-step explanation:
I believe that the answer would be B) y = x + 19
Answer:
y = 5x - 2 (0, 2) (1, 4) (2, 7) (3, 13)
