If we find that the null hypothesis, Upper H Subscript 0 Baseline colon beta Subscript j Baseline equals 0, cannot be rejected when testing the contribution of an individual regressor variable to the model, we usually should:___________
Answer:
Remove the variable from the Model
Step-by-step explanation:
Normally, when considering which variable to keep and which one to drop when considering testing of the contribution of an individual regressor variable to the model, generally speaking we use one explanatory variable for between 10-15 observations.
Now, before we run our regression, we would need to run correlation analysis between all explanatory variables to detect if there's any multicollinearity, and also between the dependent variable and the regressors in order to determine the most important predictors to be included in the regression.
So after the analysis, for the null hypothesis not to be rejected, we will remove the variable from the Model.

Answer:
y = 9
Step-by-step explanation:
∆KLH is congruent to ∆FLH by the Hypotenuse-Leg Congruence Theorem.
Therefore,
m<KHL = m<FHL
Thus:
6y = 4y + 18
6y - 4y = 18 (subtraction property of equality)
2y = 18
y = 18/2 (division property of equality)
y = 9

What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the given information in the question,
Books read by Martha on Saturday = 1/6
Books read by Martha on Sunday = 5/12
Then, the number of books left to read is,
1 - (1/6 + 5/12)
Take LCM as 12,
[12 - (2 + 5)]/12
= (12 - 7)/12
= 5 / 12

The area of a rectangular field is 6831 m If the length of the field is 99 m, what is its width?
Answer:
The width is 69m
Step-by-step explanation:
Set it up in a equation, W x 99 = 6831. So first thing to do is get the letter by its self. So you will do the opposite of multiplication. And what you do to one side you do to the other so you divide 6831 by 99. And you get W = 69
Answer:
Step-by-step explanation:
Area of rectangular field = length × width 99×w=6831
w = 6831/99
w=69m

−2 1/6 divided by 1 1/4
100 points
Answer:
-1 11/15Step-by-step explanation:
−2 1/6 divided by 1 1/4:
-2 1/6 ÷ 1 1/4 = - 13/6 ÷ 5/4 = - 13/6 × 4/5 = - 26/15 =-1 11/151) to divide that mixed number we'll need to turn it into an improper fraction:
[tex] - 2\frac{1}{6} = - ( \frac{6 \times 2 + 1}{6} ) = - \frac{13}{6} \\ 1 \frac{1}{4} = \frac{4 \times 1 + 1}{4} = \frac{5}{4} [/tex]
2) now let's divide it, reciprocating 1 1/4 and multiplying both fractions one by another:
[tex] - \frac{13}{6} \times \frac{4}{5} = - \frac{52}{30} = - \frac{26}{15} [/tex]
3) Hence the answer is -26/15
