Answer:
A
Step-by-step explanation:
I took the test A is the correct answer
The first thing you should see in this case is that the triangles are proportional.
We have then that:
((a) / (c)) = ((d) / (a))
Step 1:
Go a multiplying:
((a) / (c)) * (a) = (d)
Step 2:
Pass c multiplying:
(a) * (a) = (d) * (c)
Step 3:
Same basis, exponents are added:
a ^ (1 + 1) = (d) * (c)
Step 4:
a ^ 2 = c * d
Finally
((a) / (c)) = ((d) / (a)) -------> a ^ 2 = c * d
Answer:
The mean of the density curve is greater than the median.
Step-by-step explanation:
The distribution is skewed right. So the mean is greater than the median. And of course, the curve is not symmetrical.
By definition, the volume of a rectangular prism is given by:
Where,
w: width
l: length
h: height
Substituting values we have:
Rewriting we have:
Clearing h we have:
Then, for power properties we have:
