Answer:
The dimensions of the lot and the walkway are shown in the diagram.
Step-by-step explanation:
Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level
No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05.
The correlation coefficient differs from zero when the p-value is less than 0.05.
Answer:
r = 4/3
Step-by-step explanation:
-20 = -15r
Divide both sides by -15.
-20 / -15 = r
The negatives cancel, so
20 / 15 = r
Simplify by taking 5 out of the numerator and denominator. 20/5 = 4, 15/5 = 3.
4 / 3 = r
<u>So r = 4/3.</u>
When a line passes through the two points
, its slope is given by the formula 
In this question, a line L passes through the points 
So, its slope is given by

When two lines are perpendicular, then the product of their slopes is -1.
Since, the slope of the line L is
, so the slope of the line which is perpendicular to the given line L is
as the product of
.
