Answer:
? We don't see any graphs to choose from
Step-by-step explanation:
Graph a dotted line (to show it's not included) with y-intercept 1 and slope 1/2. Test the origin (0, 0) in the inequality:
This is true, so shade the side of the line that the origin is on (above the line).
Next inequality...
Graph a solid line with y=intercept 1 and slope 1. Test the origin.
True! Shade the side of the line the origin is on (below the line). See image2, attached.
Graph a dotted line with y-intercept -1 and slope -2. Test the origin (0, 0).
True, so shade the side the origin is on (above the line).
The solutions are located where all the shadings intersect. See image3. The solutions are above the red line, above the green line and below the blue line.
Answer:
3 hours is your answer
Step-by-step explanation:
Answer:
x < -16, none of the solution sets are correct for the given equation.
Step-by-step explanation:
-1/4x > 4, multiply both sides by -4, don't forget when you multiply or divide by a negative you have to flip the sign.
x < -16
none of the solution sets are correct for the given equation.
Answer:
c. 64% of the variation in the weight of luggage is explained by the number of passengers
Step-by-step explanation:
The explained variance is a measure given by the coefficient of determination, R².
The value Given above is the correlation Coefficient, R, which is 0.8
The Coefficient of determination, R² = 0.8² = 0.64, expressing as a percentage ; 0.64 * 100% = 64%
This means that 64% of the variation in the dependent variable is can be explained by the regression line. (independent variable)
