Answer:
Fabric used by each each player for headband is 16.51 inches and fabric used for wristband is 1.99 inches
Step-by-step explanation:
In first case it is given that there are players and 2 coaches
So total number = 44+2 = 46
It is given that 759.46 inches of fabric is used on headbands for 44 players and 2 coaches
So fabric used by each player 
Now in second 87.64 inches fabric is used for 44 players
So fabric used by each players 
So fabric used by wristband is 1.99 inches
The first quartile is from the first dot to first vertical line, which is 13-15.5.
The maximum is the right most dot, which is 35.
The median is the line in the box, which is 10.5.
Answer:
Line LM
Step-by-step explanation:
First, we need to know what the slope is of a line that would be perpendicular to a line with a slope of -5/6. To find this, we take the reciprocal and multiply it by -1. Therefore, the line we are looking for needs to have a slope of 6/5.
Based on the fact that the slope is positive, we can eliminate lines PQ and JK as they have a negative slope. This leaves us with lines LM and NO.
To find out whether or not it is between LM and NO, you could eyeball it by looking at the graph and simply counting which might be faster if you understand how to do that (rise/run), or you can use the pair of coordinates given to you on each line to calculate for slope.
Line LM - 
Line NO - 
Based on this, we know that line LM is perpendicular to a line that has a slope of -5/6.

The correct statement are the first and the second
=======================================
The first statement:
y = (-2/3) x - (13/3)
slope = -2/3 and passing through (4,-7) because (-2/3) *4 - (13/3) = -7
the slope of the parallel line = -4/6 = -2/3
============================================================
The second statement
y = (-7/2) x - (5/2)
slope = -7/2 and passing through (-3,8) because (-7/2) *-3 - (5/2) = 8
the slope of the perpendicular line = 2/7
the multiplication of the two slopes = -7/2 * 2/7 = -1
============================================================
The third is false
because the lines are parallel not perpendicular
the fourth is false
because the lines are perpendicular not parallel
