A) what value represents the 40th percentile of these returns?

1 answer:

4 0

<span>You need to look at the scale of different values and find one which is in the 40th percentile. This means 40 percent are higher and 60 percent are lower than the value you select. This can be done by figuring out the middle and going up a bit.</span>

What is the distance between (1, -4) and (1, 18

Annette [7]

<h3>Answer: 22 units</h3>

=====================================================

Explanation:

You can use the distance formula

$d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{ (1-1)^2 + (-4-18)^2}\\\\d = \sqrt{ (0)^2 + (-22)^2}\\\\d = \sqrt{ 22^2}\\\\d = 22\\\\$

----------------

A shorter method is to subtract the y coordinates and apply absolute value

So either |-4-18| = |-22| = 22

Or, |18 - (-4)| = |18+4| = |22| = 22

This method only works because the x coordinates are the same. We can also use this method if the y coordinates were the same with the x coordinates being different.

It is given that in △ABC, AD ⊥ BC. Using the definition of sine with angle C in △ACD results in sin(C) = . Using the multiplicat

amid [387]

We see here in the diagram that the base is a. We know this because the height is perpendicular to it. We also know the height is bsin(C) which, when replace h for bsin(C) and a for the base, we get A=absin(C), which is the second option.
