If it is not C it is D, but i am pretty sure its c
Answer:
1) Given
2) Slope Formula
3) Multiply
4) If the product of the slopes of two non vertical lines is -1, then the lines are perpendicular
5) Perpendicular lines intersect to form right angles
6) Definition of right triangle
The slope is 1. meaning up 1 and over 1
the y intercept is (0, -2)
when x is 1 y is -1 (1, -1)
when x is 2 y is 0 ( 2, 0)
hope that helps
The sample mean is an unbiased estimate of the population
mean. This tells us that the mean of all sample means is equal to the
population mean. Since we know that the population mean is 5.67, we also know
that the mean of sample means is also 5.67.
