Step-by-step explanation:
Hi there!
We are given the points (-1,2) and (3,3) and we need to find the slope.
The formula for slope calculated from two points is , where (
,
) and (
,
) are points
since we have two points, we can substitute them into the formula, but let's label their values to avoid any confusion
=-1
=2
=3
=3
now substitute into the formula (m is the slope); remember: we have a negative number in this, so we'll be subtracting a negative.
m=
simplify
m=
m=
so <u>B </u>is your answer
Hope this helps! :)
Answer:
Step-by-step explanation:
Given : Significance level :
Sample size : n=85
Critical value :
Sample mean :
Standard deviation :
The confidence interval for population mean is given by :-
Thus, the 95% confidence interval for the true mean cholesterol content, μ, of all such eggs =
Hence, we conclude that the true population mean of amount of cholesterol lies between 182.356 and 197.644.
Slope = (y2 - y1)/(x2 - x1)
Given the points (2, 2) & (-4, -3)
