Answer:
Step-by-step explanation:
The expression (t•s)(x) means t(s(x)) or t of s of x. It means to substitute s(x) into the equation for t(x).
Which lines are parallel in the square pyramid?
2 answers:
A square pyramid is a pyramid with a square base. In this problem, this base is formed by the points B, C, D and E as illustrated in the Figure above. So, the correct answers are:
First. (BC←→ and DE←→)
This is indicated in Figure 1. As you can see, the red lines are parallel, that is:
Recall that two lines are parallel if they are always the same distant apart in which case they are <em>equidistant, </em>that is, they never meet.
Second. (CD←→ and BE←→)
This is indicated in Figure 2. As you can see, the green lines are parallel, that is:

The confidence interval is given by
where
is the sample mean and 
is the standard error of the mean. In turn, the standard error of the mean is 
where 
is sample size.
We have
The endpoints of the confidence interval correspond to the finite endpoints of the rejection region. That is,
for which we can solve for
. We get
which is the critical value for a confidence level of
.
