Given: f(x) = x - 7 and h(x) = 2x + 3
2 answers:
<u>Answer:</u>
The correct answer option is h(f(x)) = 2x - 11
<u>Step-by-step explanation:</u>
We are given two functions:
and
and we supposed to find another function which is .
To find , we need to substitute the value of
in the other function i.e.
to get:
Therefore, the correct answer is h(f(x)) = 2x - 11.

Answer:
And then replacing in the total probability formula we got:
And rounded we got
That represent the probability that it rains over the weekend (either Saturday or Sunday)
Step-by-step explanation:
We can define the following notaton for the events:
A = It rains over the Saturday
B = It rains over the Sunday
We have the probabilities for these two events given:
And we are interested on the probability that it rains over the weekend (either Saturday or Sunday), so we want to find this probability:
And for this case we can use the total probability rule given by:
And since we are assuming the events independent we can find the probability of intersection like this:
And then replacing in the total probability formula we got:
And rounded we got
That represent the probability that it rains over the weekend (either Saturday or Sunday)
