Answer:
A (point) is the answer to the question.
What is the sample size, and how many people are you finding the probability out of? How many like fishing? I need more data, thanks.
Answer:
subscripts identify different instances of objects that have a similar meaning or definition
Step-by-step explanation:
You apparently are interested in the meaning of the subscript N in the explicit formula ...
Here, it is used to identify different terms of a sequence. When a value is substituted for N, it replaces all instances of N. Using your example, the first three values of are ...
So, if you're asked to find the 20th term of the sequence, you put 20 where N is, then do the arithmetic.

Subscripts are also used to identify elements of a matrix or coordinates in multiple dimensions. For this purpose, there may be 2 (or more) subscripts, whose order has meaning. The subscripts 24, for example, in refer to row 2, column 4 of a matrix named A. That is, the subscripts are in row, column order.
In short, subscripts are used to identify different instances of similar objects.
Before multiplying two fractions together, always try to cross-cancel.
So in this problem, the 13 and 39 cross-cancel to 1 and 3.
So we have 1/15 × 11/3 which is 11/45.
Remember, multiply across the numerators and denominators.
The length (L), width (W), and the diagonal (D) of the television screen make a right triangle with the legs L and W and hypotenuse D. Thus, their measurements are related through Pythagorean Theorem.
L² + W² = D²
Substituting the known values from the given,
(15 in)² + W² = (25 in)²
Solving for W in the equation gives, W = 20 in and W = -20. The second value is an extraneous root. Thus, the width of the television screen is 20 inches.
