First, we can write the equation of the line using the information provided:

Now, we can create a table:
Finally, we can graph the line:
Answer:
x=6
Step-by-step explanation:
(x*3)+4=22
Subtracting 4 from both sides:
(x*3)=18
Dividing both sides by 3:
x=6
Hope this helps!
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation is 
The safest water level is between 7.2 and 7.8
Generally the probability that the selected pool has a pH level that is not considered safe is mathematically represented as

Here

Generally 
So
=>
From the z-table the probability of (Z < -1.5) and ( Z <1.5) are

and

So
So

=> 
B. The equation is 4x = -48. Ben’s point total is -12.
