Answer:
Option a) u is called the "error term". It is the error we make in prediction
Option d) x is called the independent variable because x is independent from y and u.
Step-by-step explanation:
We are given the following information in the question:

where y is the dependent variable, x is the independent variable.
: It is the value of y when x is zero, that is y-intercept.
: It is the coefficient of x in predicting the dependent variable y.
u is the error term.
- An error term represents the margin of error.
- It refers to the sum of the deviations within the regression line, that is the difference between the predicted value and the observed value of y.
Thus, Option A) u is the error term and Option D) x is called the independent variable because x is independent from y and u are the correct answer.
The awnser to ur question is A because take 2.3 time 3 and get 6.9 and then add the 108 and -3 and get 105
For A (x+6), (y-2)
For B (x+6), (y-2)
For C (x+2), (y+2)
Good luck
Answer:
70 degrees
Step-by-step explanation:
The adjacent angles in a parallelogram are supplementary and add to 180 degrees
∠CDE+∠DEF=180
We know that ∠CDE is 110 degrees, so we can substitute that in
∠CDE+∠DEF=180
110+∠DEF=180
Subtract 110 from both sides
∠DEF= 70
So, ∠E is 70 degrees
The length of its diagonal in terms of r and s is √r² + s²
In order to get the length of the diagonal of a triangle, we will use the Pythagoras theorem:
Pythagoras theorem states that the sum of the square of the diagonal is equal to the sum of the square of the other two sides.
Given the following
Length = r feet
width = s feet
The diagonal "l" will be expressed as;
l² = r² + s²
Take the square root of both sides
√l² = √r² + s²
l = √r² + s²
Hence the length of its diagonal in terms of r and s is √r² + s²
