Answer:
C) y = 12 x Represents the proportional relationship.
Step-by-step explanation:
Two quantities P and Q are said to be proportional if and only if:
Here: K = Proportionality Constant
Now, here the given expression are:
So, y is NOT PROPORTIONAL to x.
So, y is NOT PROPORTIONAL to x.
So, y is PROPORTIONAL to x.
So, y is NOT PROPORTIONAL to x.
<h2>Answer with explanation:</h2>
A box contains 12 balls numbered 1 through 12.
Also the ball are drawn without replacement.
a)
The probability that the first ball had a smaller number on it.
i.e. the number on the first ball could be: {1,2,3}
Hence, the probability that the first ball had a smaller number on it is:
b)
The probability that the first ball has a even number on it is:
There are total 6 even numbers {2,4,6,8,10,12}
but 4 can't be considered as it comes on the second draw, so we are left with just 5 balls with even number.
Hence, the probability is:
