Answer:
Step-by-step explanation:
Our Sample size is 42 rocks total. If we want to pick one red rock out of the 42, we first have to determine the possibility of doing that from the numbeer of red rocks we have total. There are 6 red rocks, so the probability of picking one of those is
6/42 or 1/7
There are 14 blue rocks. So the probability of picking one of those is
14/42 or 1/3
There are 22 white rocks. So the probability of picking one of those is
22/42 or 11/21
Answer:
y = 5x/7 + 10/-7
Step-by-step explanation:
subtract 5x from both side and you should get -7y = -5x + 10
divide negative 7 into both side -7/-7 = -5x/-7 + 10/-7
and the answer is y = 5x/7 + 10/-7
Question 1:
Choir A - 129.5 = 130
Choir B - 130.1 = 130
Choir C - 130.8 = 131
Choir D - 129.8 = 130
Answer - Choir C
Question 2:
132 = 1/2x + 2(x - 9)
= 1/2(60) + 2(60 - 9)
= 30 + 102
= 132
60 - 9 = 51
