Answer:
24% saline
Step-by-step explanation:
Find how much saline is in both solutions:
7(0.27)
= 1.89
3(0.17)
= 0.51
Add this together:
1.89 + 0.51
= 2.4
Since there are 10 quarts in total, the concentration of the mixture can be found by dividing 2.4 by 10:
2.4/10
= 0.24
So, the concentration of the mixture is 24% saline
Hello there!
Median is the middle of the data set.
So, first we have to arrange it into proper numerical order (least to greatest).
2,6,10,12,15
Then, we look for the middle number.
It is 10, therefore 10 would be the median of this data set.
