Answer:
The total weight is 1593 lbs.
Step-by-step explanation:
177*9 = 1593
Good morning. I’m sorry to say I can’t really see what the numbers are in your photo. I zoomed in and circled what I could on my picture.
For your first question (6), subtract the difference between the two points that I have circled. Each of those marks the upper quartile for each team.
For (7), I need to know which line or dot is 210. If it’s the line in the middle of the box, the answer is 50%. If it’s the line at the right side of the box, the answer is 75%
For (8), again, I need your help to know where 220 is.
If you can put some answers in the comments, I’m happy to keep helping you.

Answer:
no real solutions; k = ±i(2/3)√15
Step-by-step explanation:
If k is one of the roots, then substituting it for x will satisfy the equation:
k -4k -20/k = 0
Multiplying by k gives ...
-3k^2 -20 = 0
k^2 = -20/3 = -6 2/3
There are no real values of k such that this is true.
__
If we allow k to be imaginary, then ...
k = ±i√(20/3) = ±i(2/3)√15
Possible imaginary values of k are ±(2/3)√15.
