All you have to do here is replace f(x) with x + 2 and h(x) with 1/x-1.
It's like plugging in a number for x, but instead you are plugging in a whole function instead of just a number. Whenever you are pluging something in, whatever it is, make sure it is in parentheses: ( ) always!
Until your understanding of algebra becomes stronger.
2f(x)-hx
First lets plug in x + 2 for f(x). It's gonna look like this:
2(x + 2) - h(x)
Notice how I put x + 2 in parentheses next to the 2, you
a l w a y s want to do this. Now we just do the same for h(x):
2(x + 2) - (1/x - 1)
And that's it. That's all you have to do.
Answer:
a) 0.5
Step-by-step explanation:
a)
Let T be the event that person uses trails daily and E be the event that person uses trails for exercise.
We have to find the probability that person uses the trails for exercise given that the person uses trails daily which can be denoted as P(E/T).
P(E/T)= P(E∩T)/P(T)
We are given that P(T)=0.24 and P(E∩T)=0.12. So,
P(E/T)= 0.12/0.24
P(E/T)= 0.5
Thus, the probability that person uses the trails for exercise given that the person uses trails daily is 50%
