Answer: a. −0.41
Step-by-step explanation:
The slope for the best-fitting linear equation is given by :-
where , =sum of squared deviations from the mean of X.
= correlation between y and x in terms of the corrected sum of products.
As per given , we have
Then, the value of the slope for the best-fitting linear equation will be
Hence, the value of the slope for the best-fitting linear equation= -0.41
So the correct answer is a. −0.41 .
Answer:
B
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
First, you look at which way it is going. From left to right, the line is going down, so the slope is negative. Change in y is 3 and change in x is 1. From any two points on the line, the y value changes by 3 every time the x value changes by 1.
For this case we have the following system of equations:
Substituting the second equation into the first we have:
The equality is not fulfilled, therefore the system has no solution.
The lines do not intersect.
Answer:
The system has no solution.
Hey there!
In order to find out which one is greater, lets convert both of them into percents.
To convert a decimal into a percent, simply multiply the decimal by 100 or move the decimal two places to the right.
So!
0.086 × 100 = 8.6%
Now, we know that 0.086 is equal to 8.6% So, the correct answer is 86%
86% is greater than 0.086.
