<u><em>Answer:</em></u>
Andrew's height is 
meters
<em><u>Explanation:</u></em>
We know that John's height is 
meters
<u>We are given that:</u>
John is 
meters shorter than Paul
<u>This means that:</u>
Paul's height = John's height +
Paul's height = 
meter
<u>We are given that:</u>
Paul is 0.25 meters taller than Andrew
<u>This means that:</u>
Andrew's height = Paul's height - 0.25
Andrew's height = 
meters
Hope this helps :)
The median is 7. By definition of "median," half of the data values are below 7; half are above 7. Thus, the first statement is FALSE.
Spread: in the 2nd statement we are comparing the spread from lower quartile (4) to the median (7) and that from the median (7) to the upper quartile (9). In other words, we're comparing 3 to 2. This statement is TRUE.
The 3rd statement is the opp. of the 2nd statement, and thus is FALSE.
The 4th statement is FALSE. See my comments regarding the 1st statement.

Step-by-step explanation:
Alright, archtan /
tan
−
1
(
x
)
is the inverse of tangent. Tan is
sin
cos
. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.
Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.
Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.
Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.
the answer is m=-3n-5/2 or n=2m+5/6
