Hi!
I would approach this question by first looking at where the parallelogram is located, by graphing the image. I did so and drew a rough image on Paint (See attached image)
To get the part where the diagonals intersect, I would find the midpoint of the line between points (1, 3) and (5,-9) (or the other pair). The reason is a parallelogram's diagonals always bisect each other, meaning the point they intersect is always the middle of the two diagonals.
Therefore, you can find the midpoint of a diagonal, between (1, 3) and (5, -9). The midpoint theorem is (
.
Take the points (1, 3) and (5, -9), and fill them in.
Then solve.
(3, -3)
If you'd like to check the other midpoint:
Take the points, (8, 3) and (-2, -9)
Then solve.
(3, -3)
They're the same, so that answer is correct.
Hope this helps!
O my gosh I can't solve this
The expression equivalent to <span> ^4 sqrt 144a^12 b^3 will be found by simplifying our expression as follows:
</span><span> ^4 sqrt 144a^12 b^3
=(144a^12b^3)^(1/4)
=(12^2a^12b^3)^(1/4)
=12^(1/4*2)a^(12*1/4)b^(3*1/4)
=12^(1/2)a^3b^(3/4)
Answer: </span>12^(1/2)a^3b^(3/4)
Answer:
Where 
and 
We select a sample size of n =8. Since the distribution for X is normal then we know that the distribution for the sample mean 
is given by:
And the standard error would be:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
Let X the random variable that represent the compressive strength of concrete of a population, and for this case we know the distribution for X is given by:
Where and
We select a sample size of n =8. Since the distribution for X is normal then we know that the distribution for the sample mean is given by:
And the standard error would be:
Answer:
B.) The data in country B are more symmetric than the data in country A.
