Sure. What do you need help with exactly?
The mean of the sample given by 44,22,11,17,21 will be given by:
the sum of x's will be:
44+22+11+17+21
=115
n=5
therefore the mean will be:
μ=115/5
=23
In the first statement, it is false. -2+14 would not add up to 16.
In the third statement, it is false. -8+-2 would not add up to 16.
In the fourth statement, it is false. -2-14 would not add up to 16.
So the second statement is true -2+18=16.
The expression that's always true is that D. a+c > b+d.
<h3>How to illustrate the information?</h3>
From the information given, it should be noted that we are told that a is less than b and c is less than d.
We are also informed that all the variables that are given are less than 0. Let's say a = -1, b = -2, c = -3 and d = -4.
Therefore, the expression that's always true is that. a+c > b+d. This will be:
= (-1 - 2) > (-3 - 4)
= -3 > -7
Based on the information given, the expression that is true is a+c > b+d.
Therefore, the correct option will be D.

Draw a rhombus
1. Locate the given line and the given point.<span>
2. </span>Draw the second vertex of the rhombus.- T<span>o do this, set the compass tip on the given point and draw an arc that intersects the given line at some point. Do not change the width of the compass.
3. </span>Draw the third vertex of the rhombus-<span> Using the same compass width, set the compass tip at the second vertex, and draw an arc that intersects the given line at a new point. Do not change the width of the compass.
4. </span>Draw the fourth vertex of the rhombus-<span> Using the same compass width, set the compass at the third vertex, and draw an arc that intersects the first arc you drew (through the second vertex).
5. </span>Draw a line through the first and fourth vertices of the rhombus.<span> This line will pass through the given point and be parallel to the given line, as the two lines form two opposite sides of a rhombus.
Hope this helps :))
