Answer:
About 1.23 standard deviation above the mean
Step-by-step explanation:
From what we have here, we need to calculate the difference between the given value and the mean and divide by the standard deviation
That would be through calculating the z score as follows;
z-score = (x - mean)/SD
where x is the given value
z-score = (87-71)/13 = 1.23
Since the score is bigger than the mean, the correct choice here is that the score is about 1.23 standard deviation above the mean
Volume = l x w x h
180 = l (5 x 4)
180 = 20 l
6 = l
That means that the couch will fit, because the length of the van is 6 ft, which is also the length of the couch.

The question asks for the length of CD and HJ. To find those, we need to find a connection between them.
In the given statement, it says ABCD ≅ FGHJ. When we look at the equation, the corresponding letters are equal. For example, angle A is congruent to Angle F. Or BC ≅ GH.
So we know that CD and HJ are congruent.
Set them equal:

Subtract 2x from both sides:

Subtract 2 from both sides:

If x is 3, plug it in:

Simplify:

So, HJ is 11. And because HJ ≅ CD, CD is 11 too.
