Answer:
Although the variables are related, there is not likely a causal relationship. Trees probably do not directly influence test scores as much as other factors that might be related.
Step-by-step explanation:
Answer:
Step-by-step explanation:
I take it you want x = 3
y = abs(3 - 3) + abs(3 + 2) - abs(3 - 5)
y = 0 + 5 - abs(-2)
y = 0 + 5 - (2)
y = 0 + 5 - 2
y = 3
If you meant something else please leave a note.
Now all you do is redo the problem for 5
y = abs(5 - 3) + abs(5 + 2) - abs(5 - 5)
y = abs(2) + abs(7) - abs(0)
y = 2 + 7 - 0
y = 9
Now set up your inequality
3 < y < 9
In a 10 gal of an 11% salt solution,
11% of 10 gal are sal.
11% *10 gal=(11/100)*10 gal =0.11*10 gal = 0.1 gal is salt.
Similarly, 0.07*6 gal= 0.42 gal is salt of the 6 gal in the second solution.
The mixture is 10 gal +6 gal = 16 gal, and contains a total of
0.1 gal +0.42 gal = 0.52 gal of salt.
0.52 = x% of 16
0.52=x%*16
x=(0.52/16)*100=0.0325*100=3.25
Answer: there is 0.52 gal of salt in the mixture, that is 3.25%
