The mean of four numbers is 43. What are those four numbers?
1 answer:
Answer:
42,43,43,44
Step-by-step explanation:
If there are four numbers in a list then the middle 2 numbers should be added up and divided up to give the mean. If we are given the mean we can now work backwards to give us:
(where x and y are the 2 middle numbers)
We can also see that x and y must be equal as the mean is an integer.
So:
So x=43 and that is the middle 2 numbers.
I don't exactly know how to explain how i got the other 2 numbers.

<u>Composite Function </u>
Given f(x) and h(x) real functions, the composite function named is defined as:
It can be found by substituting h into f.
We are given the functions:
It's required to find
As defined above:
Thus:
Find h(2):
h(2)=0
Now:
Answer:
Options A, D and E.
Step-by-step explanation:
Formula to calculate the volume of the triangular prism is,
Volume of the triangular prism = (Area of the triangular base)×(height)
= B × h
Area of the right triangular base =
=
= 56 m²
Volume of the prism =
= 392 cubic meter
Therefore, from the given options correct options are Option A, Option D and Option E.
