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.

3e - $\frac{3}{2}$ f - $\frac{3}{8}$

multiply each of the terms in the parenthesis by $\frac{1}{2}$

$\frac{1}{2}$ (6e - 3f - $\frac{3}{4}$ )

= 3e - $\frac{3}{2}$ f - $\frac{3}{8}$

Step-by-step explanation:

You use reverse PEMDAS.

First you would divide by 3 on both sides. This should give you:

the same type of television is being sold at two different stores. store A is selling the television for $800, which is $120 mor

svlad2 [7]

Answer: the selling price of the television at store B is $1360

Step-by-step explanation:

Assuming the selling price of the television at store B is represented by $B. Store A is selling the television for $800, which is $120 more than half the cost of the television at store B. The equation representing this situation is expressed as

800 = B/2 + 120

Multiplying the left hand side and the right hand side of the equation by 2, it becomes

1600 = B + 240

B = 1600 - 240

B = $1360
