Answer:
I don't know anything sorry for inconvenience
Answer:
140.25
Step-by-step explanation:
10/100*150=15
150+15=165
15/100*165=24.75
165-24.75=140.25

We know
In a function
x represents the input and y represents output
So
x is time
So
f(30) represents distance traveled in 30mins
Answer:
(1,3) maximum
Step-by-step explanation:
As you can see from the graph the tip of the parabola is the vertex which is at the point (1,3) which is a maximum because it is the tallest point on the graph.
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.
