Using the lengths​ (in.), chest sizes​ (in.), and weights​ (lb) of bears from a data​ set, the resulting regression equation is

Weightequalsminus274plus0.426 Lengthplus12.1 Chest Size. The​ P-value is 0.000 and the adjusted Rsquared value is 0.925. If an additional predictor variable of neck size​ (in.) is​ included, the​ P-value becomes 0.000 and the adjusted Rsquared becomes 0.933. Why is it better to use values of adjusted Rsquared instead of simply using values of Rsquared​?

Answer:

hello your question lacks the required options here are the options to the question:

a) The unadjusted R^2 decreases or remains the same as more variables are included, but the adjusted R^2 is adjusted for the number of variables and sample size

b) The unadjusted R^2 can only be calculated for regression equations with two or fewer predictor variables while the adjusted R^2 can be calculated for regression equations with any number of predictor variables

c) The unadjusted R^2 increases or remains the same as more variables are included but the unadjusted R^2 is adjusted for the number of variables and sample size

d) The unadjusted R^2 can only be calculated for regression equations with p-values greater than 0 while the adjusted R^2 can be calculated for regression equations with any manner of  p

answer : The unadjusted R^2 increases or remains the same as more variables are included but the unadjusted R^2 is adjusted for the number of variables and sample size ( C )

Step-by-step explanation:

As seen  the unadjusted  R^2 increases anytime a predictor is added to the model even if the predictor has no effect on the model i.e if it is just a chance but the adjusted R^2 has been adjusted for the exact number of predictors in the model and it would increase or decrease based on if the additional predictor added to the model improves the model significantly(more than chance) or if the predictor those not improve the model more than expected

4. Find the slope of the line that posses
Illusion [34]

Answer:

The slope is -8

Step-by-step explanation:

To find the slope, we can do a very easy equation. We can do the formula

y1 - y2 / x1 - x2

We fit in all of the respective numbers to get the equation as this.

-51-(-75) / 7-10

Then, we get

24/ -3

Simple division gives us -8.

Why doesn’t zero have an opposite
Neko [114]
Zero does not have a opposite, because it is not a positive number nor a negative number. It has no reciprocal either

Help please anybody
Sedbober [7]

put in an positive number for x and check

2 - 5 = -3

5 - 2  = 3

- 2 + 5 = 3

5 + (-2) = 2

so the only different one is the first

jolli1 [7]
No, because here mom is adding in 3.5 more pages when it say only 1.5. So she'll be able to read 30 pages because 1.5 and 20 pages of her friends is 30. So your answer is that her mom is wrong.

I hope this helped! I gave an explanation and an answer. You're Welcome!
