Answer:
a) m = 3 b = 1/5
b) y = 1/2x - 3
Step-by-step explanation:
y=mx+b
If I can read the #'s correctly:
add the yes answers together 23+147 = 170
add the no answers together 112+48= 160
so your ratio of haves to have nots is 170 to 160
but both sides can be divided by 10, so it can be simplified to 17 to 16.
Good Luck!
Answer:
0.4032
Step-by-step explanation:
1. We assume, that the number <em>72 is 100%</em> - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If <em>72 is 100%</em>, so we can write it down as <em>72=100%</em>.
4. We know, that x is <em>0.56%</em> of the output value, so we can write it down as <em>x=0.56%</em>.
5. Now we have two simple equations:
1) <em>72=100%</em>
2) <em>x=0.56%</em>
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
<em>72/x=100%/0.56%</em>
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
