Which option shows the graph of 2y-10 < 3x?
1 answer:
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
isolate the variable y
Adds 10 both sides
Divide by 2 both sides
The solution of the inequality is the shaded area below the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is (0,5) (value of y when the value of x is equal to zero)
The x-intercept of the dashed line is (-3.33,0) (value of x when the value of y is equal to zero)

Answer:
Residual = -2
The negative residual value indicates that the data point lies below the regression line.
Step-by-step explanation:
We are given a linear regression model that relates daily high temperature, in degrees Fahrenheit and number of lemonade cups sold.
Where y is the number of cups sold and x is the daily temperature in Fahrenheit.
Residual value:
A residual value basically shows the position of a data point with respect to the regression line.
A residual value of 0 is desired which means that the regression line best fits the data.
The Residual value is calculated by
Residual = Observed value - Predicted value
The predicted value of number of lemonade cups is obtained as
So the predicted value of number of lemonade cups is 23 and the observed value is 21 so the residual value is
Residual = Observed value - Predicted value
Residual = 21 - 23
Residual = -2
The negative residual value indicates that the data point lies below the regression line.
