4/3 * pi * radius^3 is the formula for volume of a sphere.
Answer:
The solution of this system is
(4). (6.0,5.4)
Step-by-step explanation:
First we have to find the equation of the line represented in the table; for that we have to find it's slope 
and it's y-intercept 
and then write it in the following form:
The slope of the line we get from first two points:
thus we have
we find by putting the point 
into the function:
Thus we have
Now we have to find where this line intersects with 
; to do this we just substitute 
with :
<em>We have the x-coordinate of the intersection.</em>
We find the y-coordinate by substituting 
into :
Thus the solution to the system is
which is option 4.
Answer:
While statistics are extremely valuable, they are also notorious for being a means that people use to make false and misleading arguments. Also far too often statistics are obtained by taking a sample from a larger group and assuming the whole group has the same characteristics as the sample.
A sample provides a smaller set of the population for review, that delivers data that is useful to represent the whole population. Surveying a smaller sample, as opposed to the entire population, can save precious time for researchers and offer urgent data.
