Since both p and q are true, ~p → q means F → T. This matches only the 4th selection, which (rightly) declares the implication to be true.
T F → T
If TWO points lie in a plane, the LINE containing them also lies in the same plane.
Answer:
Lines 2 and 4 are perpendicular
Step-by-step explanation:
Line 2: 4y=3x-4
y=3/4x - 1
Line 4: 4x+3y=-6
3y=-6-4x
y=-2 - 4/3x
The two lines are perpendicular since -4/3= - (inverse of 3/4)
answer:
A
Step-by-step explanation:
If you reflect over line A both pentagons are equally spaced in proportion to the line
Answer:
1. The sum of the residuals is always close to zero.
2.The coefficient of determination measures how much of the variation in the y-values is explained by the regression line.
3. In the equation of the least-squares regression line, y hat is a predicted value when x is known
Step-by-step explanation:
The least square regression line is a line that makes distance from data points to the regression line to be as minimal as possible. This line is a best fit for the data points. Let's say we have a collection of numbers and a scatter plot, this line is a line that exists and best fits the data.
Therefore, the least square regression line minimizes sum of squared error to be close to zero. R² measures the extent to which variations in the value of y is explained by the regression line. In the equation of this line, y hat is a predicted value when x is known.
