c
Step-by-step explanation:
it's more a gut feeling
By definition, the prism volume is given by:
Where,
Ab: base area
L: long
Substituting values we have:
Answer: The volume of the triangular prism is:
Answer:
a)
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
b)
Now we can find the means for x and y like this:
So the line would be given by:
Step-by-step explanation:
Part a
The correlation coeffcient is given by this formula:
For our case we have this:
n=4
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
Part b
Where:
With these we can find the sums:
And the slope would be:
Now we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Answer:
Step-by-step explanation:
Since angle RTS is a right angle, we have three similar triangles.
Thus,
Cross Products,
Take the square root:
Answer: one variable decreases as the other increases
Step-by-step explanation:
