They will meet back up in 40 minutes because 8x5=40 and 10x4=40 which 40 is both a multple of 8 and 10 so you're welcome
I think it is because they are both different differences
Given the dataset
We start by computing the average:
We compute the difference bewteen each element and the average:
We square those differences:
And take the average of those squared differences: we sum them
And we divide by the number of elements:
Finally, we take the square root of this quantity and we have the standard deviation:
Answer:
I'm not sure, but I think they spend 2$ for each
Step-by-step explanation:
The total items they buyed was 45. The total amount of money they spend was 95. 95 divided by 45 is 2.111111111111111111111 . So if you find 2 as one of your options, that's probably it.
The formula for a cone is given as:
<span>V = π r^2 h / 3 --->
1</span>
Where,
V = volume of the cone
r = radius of the circle base of the cone
h = is the perpendicular length from the center of the
base of the cone to the tip at the top
It was given that:
h = d
but d = 2 r, therefore:
h = 2 r
Substituting this to equation 1:
<span>V = π r^2 (2 r) / 3 </span>
V = 2 π r^3 / 3
Since r = x, the answer from the choices is:
<span>2πx3</span>
