Which characteristic of a data set makes a linear regression model unreasonable?
Answer: A correlation coefficient close to zero makes a linear regression model unreasonable.
If the correlation between the two variable is close to zero, we can not expect one variable explaining the variation in other variable. For a linear regression model to be reasonable, the most important check is to see whether the two variables are correlated. If there is correlation between the two variable, we can think of regression analysis and if there is no correlation between the two variable, it does not make sense to apply regression analysis.
Therefore, if the correlation coefficient is close to zero, the linear regression model would be unreasonable.
Answer:
5. Feet^3 or feet cubed
6. Feet^2 or feet squared
Step-by-step explanation:
5.
This is asking for the volume of this cube and the formula for that is length * width * height or l*w*h.
In any case if it doesn't have the length or width or height of the cube it would be logical to just say feet^3 or feet cubed, but if you do find one of the lengths then just multiply it by itself by 3 times for example 3*3*3.
6.
This question is asking for the surface area of the figure and that formula would be 2(wl+hl+hw), w stands for witdh l stands for length and h stands for height.
Since it doesn’t have the units listed the logical answer would be feet^2 or feet square but if you do find it just plug the numbers into the formula I gave you.
Answer:
B
Step-by-step explanation
5:1 means for every 1 table their is 5 chairs.
And for every 5 chairs there is 1 table.
Divide both the numerator and the denominator by 2, you get 20/27.
