Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
The formula of a slope:

Q1.
We have the equation of a line <em>p </em>in the standard form

Convert to the slope-intercept form:
<em>subtract 3x from both sides</em>
<em>divide both sides by (-3)</em>

The slope 
From the table we have the points (4, 3) and (7, 5). Calculate the slope of line <em>q</em>:

Divide the slope of <em>p</em> by the slope of <em>q</em>:

Q2.
Parallel line have the same slope. Therefore, if we have the equation of the line in the slope-intercept form, then we have the slope:

Q3.
Parallel line have the same slope.
Calculate the slope from given points (-11, 5) and (-6, 1):

Answer:
17.1≤x≤23.1
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = x ± z*s/√n
x is the mean yield = 20.1
z is the 80% z-score = 1.282
s is the standard deviation = 7.66
n is the sample size = 11
Substitute
CI = 20.1 ± 1.282*7.66/√11
CI = 20.1 ± 1.282*7.66/3.3166
CI = 20.1 ± 1.282*2.3095
CI = 20.1 ±2.9609
CI = (20.1-2.9609, 20.1+2.9609)
CI = (17.139, 23.0609)
hence the required confidence interval to 1dp is 17.1≤x≤23.1
Answer:
It depends, Y or X have to be set up to get an actual number because you can simply plug any numbers.
Answer: I think its $176.40
Step-by-step explanation:
The area would be 21
Feet would be = 50.4 (21 x 2.4)
Then it would cost $176.40 (50.4 x $3.50)
I might be wrong, I'm not entirely sure.
