Lasix (a drug that treats fluid retention) at 28% strength must be mixed with Lasix at 3% strength to make 40 liters of Lasix solution with a strength of 17%. Define your variables and set up a system of equations to determine how much 28% strength solution must be mixed with the 3% solution.

its c or d   take a lucky guess my dude

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail

step-by-step explanation:

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
