The number of students that play hockey is 7
The proportion is given as:



The total number of students must be a multiple of 2, 4 and 7 less than 30;
The only multiple of 2, 4 and 7 less than 30 is 28.
The number of students that play hockey is the product of 28 and the proportion that plays hockey.
So, we have:

Multiply

Hence, 7 students play hockey

Answer:
8 is the answer
Step-by-step explanation:
To solve this, we are going to use the recursive formula for a geometric sequence:

where

is the nth term of the geometric sequence.

is the first term of the geometric sequence.

is the common ratio

is the position of the term in the sequence.
We know that the starting salary is $42,000, so

. Now, to find the common ratio

, we need to find the next term in the sequence first:
We know from our problem that t<span>he company automatically gives a raise of 3% per year, so the next term in the sequence will be 42000 + 3%(42000) = 42000 + 1260 = 43260. Remember that the common ratio is the current term of the geometric sequence divided by the previous term of the sequence; we know that our current term is 43260 and the previous term is 42000, so:
</span>


<span>Now we can plug the values in our recursive formula:
</span>


We can conclude that the recursive definition for the geometric sequence formed by the salary increase is:
F(x,y) =3x + 5y (hope this helps )
