<u>ANSWER</u>

<u>EXPLANATION</u>
Given 
and

We want to find

This means we substitute the function
in to another function
and evaluate.
This implies that;

We expand the parenthesis to obtain;

We simplify further to obtain;

Hence the correct answer is A
So, this is a rate problem, so the forumla we would get is
2.5g=30
(Note this is not one of the choices), so if we look, there is an equivelent equation.
If we divide both sides by g we get
2.5=30/g
B is the correct answer

Answer: 6.93</h3>
Work Shown:
Use the pythagorean theorem to find x
a^2 + b^2 = c^2
x^2 + 11^2 = 13^2
x^2 + 121 = 169
x^2 = 169 - 121
x^2 = 48
x = sqrt(48)
x = 6.92820323027551
x = 6.93

Answer:
0.643
Step-by-step explanation:
Let, s = play a sport
c = participate in a club
P(s) = 0.14
P(s n c) = 0.09
probability that a student participates in
a club given that they also play a sport = P(c | s)
P(c | s) = P(c n s) / P(s)
P(c | s) = 0.09 / 0.14
P(c | s) = 0.64285
= 0.643
