If the quotient is positive, we know that the two integers are either both positive or both negative.
If the quotient is negative, we know that one integer is positive and the other is negative.
If the quotient is zero, then we are dividing 0 by some non-zero integer.
Answer:
142°
Step-by-step explanation:

In order to compare two fractions, they must both have the same denominator. In this case, we'll begin by converting 1/4 to twelfths. Multiply the denominator of 1/4 by 3:
4 × 3 = 12
This gives us 1/12. But to avoid changing the overall value of the fraction, we must also multiply the numerator of 1/4 by 3:
1 × 3 = 3
This leaves us with a final value of 3/12. We have now proven that 1/4 is equal to 3/12. This is the answer to your question:
A) 1/4 = 3/12
I hope this helps!
Answer:
B. The coefficient of determination is 54.76%. Therefore, 54.76% of the variation in weight can be explained by the regression line.
Step-by-step explanation:
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
The coefficient of determination is a measure to quantify how a model explains an dependent variable.
The formula for the correlation coeffcient is given by:
![r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bn%28%5Csum%20xy%29-%28%5Csum%20x%29%28%5Csum%20y%29%7D%7B%5Csqrt%7B%5Bn%5Csum%20x%5E2%20-%28%5Csum%20x%29%5E2%5D%5Bn%5Csum%20y%5E2%20-%28%5Csum%20y%29%5E2%5D%7D%7D)
The formula for the coefficient of determination is 
In our case the correlation coefficient obtained was 0.74
And the determination coefficient is
, and if we convert this into % we got 54.76%
Assume that height is the predictor (X) and weight is the response (Y)
And the best answer for this case is:
B. The coefficient of determination is 54.76%. Therefore, 54.76% of the variation in weight can be explained by the regression line.
Answer:
l = A / w
Step-by-step explanation:
Given:
A = lw
Where,
A = area
l = length
w = width
write a formula for the length
A = lw
Divide both sides by w
A / w = lw / w
A / w = l
It can also be written as
l = A / w
That is, length = Area / width
However, no baking sheet is shown
The formula to find the length of the baking sheet = Area / width
