The equation of a line in slope-intercept form that is perpendicular to the line x - 5y = 20 isy = -5x + c
<h3>How to determine the equation of the line?</h3>
The line equation is given as:
x - 5y = 20
Rewrite the above equation as
-5y = -x + 20
Divide both sides by -5
y = 0.2x - 4
A linear equation is represented as
y = mx + c
Where m is the slope
This means that the slope of y = 0.2x - 4 is
m = 0.2
The slope of a perpendicular line is
Slope = -1/m
So, we have
m = -1/0.2
Evaluate
m = -5
Substitute m = -5 in y = mx + c
y = -5x + c
Hence, the equation of a line in slope-intercept form that is perpendicular to the line x - 5y = 20 isy = -5x + c

Answer:
(3x-2)^2
Step-by-step explanation:
9x^2+6x+6x+4 now factor the first and second pair of terms...
3x(3x+2)+2(3x+2) which is equal to:
(3x+2)(3x+2) which is just:
(3x+2)^2
Answer: 7179489.4507
Step-by-step explanation:
Using the Central Limit Theorem, it is found that each random sample must have at least 10 parents supporting the change and 10 opposing.
<h3>What does the Central Limit Theorem state?</h3>
It states that for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportion is approximately normal with mean
and standard deviation
, as long as
and
.
For the test hpyothesis, two conditions are needed:
- The sampling distribution must be approximately normal.
Hence each random sample must have at least 10 parents supporting the change and 10 opposing.
