Man tbh wth is this at this point just trow that mug out the window
Answer:
must also be positive
Step-by-step explanation:
The sign of the correlation coefficient indicates whether the fitted line is sloping upwards or downwards, so it should be consistent with the sign of the slope of the fitted line. so if the correlation line is poitive so should the regression line
The domain of the function is x > 0 and the range of the function is -∞ < f(x) < ∞
<h3>How to determine the domain?</h3>
The table represents a logarithmic function.
The domain represents the set of x values.
From the table, we can see that all the x values are positive values i.e. x > 0
Hence, the domain of the function is x > 0
<h3>How to determine the range?</h3>
From the table, the table outputs all zero, positive and negative numbers
This means that the range is the set of all real numbers.
Hence, the range of the function is -∞ < f(x) < ∞

Answer:
20 miles with an error margin of ± 8 miles
Step-by-step explanation:
The margin of error of a result is the range in which an error can vary. To find the margin of error between both distances we have to
28-12 = 16, that is, the variation of the result has a range of 16 miles. So we will look for the midpoint of both distances
(X2-X1)/2+X1=(28-12)/2+12=16/2+12=8+12=20
So from this midpoint the value can vary between 8 points below and 8 points above that would cover the difference of 16 miles that we observed at the beginning
In this way, the correct answer is 20 miles with an error margin of ± 8 miles
Done
