B is false, since by the inclusion/exclusion principle,
By independence, we have , which is zero if either of or is 0, which isn't guaranteed.
2.6 because you substract
Answer:
Step-by-step explanation:
Given
Regression Equation:
Required
Determine the slope of the regression line
The equation of regression is of the form
Where b represents the slope;
Compare to the given equation
We have that:
Hence; the slope is:
So you said 20% is xx???
If 20% is xx or x^2 (x squared) then 100% must be 5x^2, since 20% times 5 would get you 100%.
Answer:
b)-15 ÷ 5
It's the only one that ends up with a negative answer, which makes sense because the temperature decreases
