We are given different amount of time that a customer interacted with a person (you) and we asked to get the average of those time.
Simply, we add all the data and divide it by the total number of data.
So,
average = (2 + 3 + 6 + 8 + 4) / 5
average = 23 / 5
average = 4.6 minutes

Answer:
The lateral area would be multiplied by 9
Explanation:
The lateral area of the cylinder can be calculated as follows:
lateral area = 2πrh
where:
r is the radius
h is the height
We are given that:
radius is multiplied by 3. This means that new radius is 3r
height is multiplied by 3. This means that new height is 3h
Substitute in the formula of the lateral area as follows:
lateral area = 2π(3r)(3h)
lateral area = 2*9*πrh
lateral area = 18πrh
Comparing the original lateral area with the new one, we would find that it is multiplied by 9
Hope this helps :)
Answer:
AB = 25
Step-by-step explanation:
First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = 
, this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle 
times larger than the corresponding side on the small triangle. That means AB is times larger than BC as well. So multiply BC by get us the answer.
<span>(f o g)(4) = f(g(4))
so
g(4) = </span><span>-2(4) -6 = -14
</span>f(g(4)) = <span>3(-14) -7 = -49
answer
</span><span> (f o g)(4) = -49</span>
