Step-by-step explanation:
6x = 23² - 17²
6x = (23 + 17)(23 - 17)
6x = 40 * 6
Hence x = 40.
Answer:
a)
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
b)
Now we can find the means for x and y like this:
So the line would be given by:
Step-by-step explanation:
Part a
The correlation coeffcient is given by this formula:
For our case we have this:
n=4
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
Part b
Where:
With these we can find the sums:
And the slope would be:
Now we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
angle ABC and angle DEF are congruent because both the angles (ABC and DEF) are alternate exterior angles of two parallel lines and a transversal.Also, angle CBE and and DEB are congruent because alternate interior angles formed by parallel lines and a transversal are also equal.
Answer:
-11/6
Step-by-step explanation:
15 - 4 = 11
4 - 10 = -6
11/-6 = -11/6
Don't make the fraction a mixed number when it comes with slope. Keep it as an improper fraction.
Sqrt(90^2+90^2)
=90*sqrt(2)
=127 ( to nearest foot)
The distance between the first base and third base is 127feet.
