X(x-2) = 15 where x = the unknown number
If you test all the answers in that equation, both x values in answer A yield 15, so the answer is A
The sample space of the experiment is the elements in the set
The sample space {Head, Tail} and there are 2 outcomes in the sample space
<h3>How to determine the sample space?</h3>
From the complete question, the experiment is a toss of a coin
A coin has a head and a tail.
So, the sample space (S) is:
S= {Head, Tail}
The number of outcomes in the above sample space is 2
Hence, the sample space {Head, Tail} and there are 2 outcomes in the sample space

or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
Let x represent the total length of the board so as to allow for the cutting of 5 lengths.
Since each length needed to be cut is 234 feet, hence:
x = number of lengths × feet per board
x = 5 lengths × 234 feet
x = 1170 feet
Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
