Hey there,
This is a two-step problem and two equations are involved in figuring out the problems.
Looking at the points you know the y-intercept of both equations but you would need to solve for the slope.
First Step:
= 
The slope of the first equation would be 
now we write it in slope intercept form and get y = x + 1.
Second Step:
Perpendicular lines have slopes that are the negative reciprocal of the original line. So the perpendicular line would have the slope as 
.
The equation would be: y = x - 2

So,
120 gal./min.
There are 4 qt. in a gal.
Multiply 120 by 4.
120(4) = 480 qt.
The pool is being drained at a rate of 480 qt./min.
Now, since there are 60 min. in an hr., multiply 480 by 60.
480(60) = 28,800 qt./hr.
The pool is being drained at a rate of 28,800 qt./hr. (quarts per hour)
Answer:
Step-by-step explanation:
If the number is 6 then square of 6 is 36 then adding 7 = 36 + 8 = 43
So the number is 6
We have different values asociated here, but easly we can also start
calculating the confidence level from a lower value.
We can define a confidence level of x%, then the asociated level of significance will be
Here for 
Defining the p-value as 0.052 we have a range between the test reject,
that is,
, for the p-value
But when we do the calculation we note that if 
; the test reject 
That's mean that the asociated confidence interval won't contain 0.
Evaluating for the value of 90 and 94, 90 causes the hypothesis to be rejected immediately, but 94 does not.
The lowest number for this approximation in the response ranges should be the number immediately above 90%, that is, the answer is 94%.
Answer:
-6
Step-by-step explanation:
28/4=7
7*5=35
29-35=-6
