First we put the numbers in order...
8,12,12,14,22,28,30
the median (middle number) is 14 <==
Answer:
(0, 4)
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis when x = 0. Since you are given the graph, you can see that when x = 0, the graph crosses y = 4, so our y-int is (0, 4).
You will use x amount of 60% solution and y amount of water. Altogether, you will make 10 L of 50% solution. The first equation is: x + y = 10 Do you understand it so far?
