Answer:
all real numbers
Step-by-step explanation:
the answer is all real numbers.
we know this since if you plug in any value for x we will get a real number.
hope this helps
When using simulation models for random sampling, we can develop the margin of error by multiplying the critical value by the standard error.
<h3>What is the margin or error?</h3>
This is a measure of the error that we get when we use a random sampling model.
It can be found by the formula:
= Critical value x Standard error
If using a z-test, the critical value would be z and the standard error would be (σ / √n). The margin or error would therefore be:
= z (σ / √n)

Answer:
-32ft
Step-by-step explanation:
Given parameters:
Original depth of the submarine = -18ft
New depth = -50ft
Unknown:
Change in depth = ?
Solution:
The change in depth will be the difference in depth between the new and original depth.
Change in depth = New depth - original depth
Change in depth = -50ft - (-18ft) = -32ft
The change in depth of the submarine is -32ft.
