1.  You'll need to download this data, or copy it down by hand.
2.  Rearrange the data from lowest to highest values.
3.  You have 24 data points (an even number). 
       In this case, to find the 1st quadrant, take the left half (that is, the left 12) data points.  Since 12 is an even number, you must find the average of the middle two of these 12 data points.  Your result is the 1st quadrant.
      To find the 3rd quadrant, find the middle two data points of the right-hand 12 data points.  Average these two points.  The result is the 3rd quadrant.

Who knows the answer for this question
Vadim26 [7]

Answer: 7

Work: So, the goal is to get z alone, so we are going to add 85 on both sides, cancelling on the side it's currently on. So, the new equation is going to be 25z = 175. Then, to get z even more lonely, we are going to divide 25 on both sides, and again cancelling it on the side it's currently on. So, the answer is z = 7. I hope this helps, and Happy Holidays! :)

1) cscΘ = - 2

=>

        1
      ------ = - 2
      sinΘ

=> sinΘ = - 0.5 => Θ is in the third and fourth quadrant

=> Θ = 180° + 30° = 210°

and Θ = 360° + 30° = 330°

2) tan Θ = √3

=> Θ = 60° and Θ = 180° + 60° = 240°
