Answer:
-20/33
Step-by-step explanation:
y2 - y1 / x2 - x1
1/6 - (-1/4) / -5/16 - 3/8
5/12 / -11/16
= -20/33
Answer:
of aikong study time was spent studying english
Step-by-step explanation:
Given:
Time spent by ailing in studying science= 3/8
Time spent by ailing in studying English= 2/5 as much time studying English
To Find:
Ailing study time was spent studying English=?
Solution:
Let the time spent by Ailing in studying English be X
Then
We know that ailing spent 2/5 as much time studying English to study English
So ,
X=
X=
X=
X=
Answer:
residual value = 0.0749.
the residual is positive, the actual winning percent for this team is more than what is predicted by the regression line.
Step-by-step explanation:
By the least squares regression equation
Predicted Value = ^y^=2.94X - 0.4873
The residual is the difference between the observed value and the predicted value of y. So, when x = 0.3260,
the regression line predicts ^y^ = 2.94(0.3260) - 0.4873 = 0.47114.
The observed value of y is 0.5460.
Therefore, residual = 0.5460 - 0.4711= 0.0749.
Since the residual is positive, the actual winning percent for this team is more than what is predicted by the regression line.

you turn the 3 and 8 to zeros and get 3.00

Slope-intercept form is y = mx + b
So we can manage to do this:
(y - yo) = m.(x - xo)
Where (x, y) and (xo, yo) are points of this line, this way we can discover the slope.
(7 - 2) = m.(1 - 0)
5 = m
m = 5
So,
y = 5x + b
Now we still have to use (y - yo) = m.(x - xo), but this time we will put only 1 point and the slope.
(y - yo) = m.(x - xo)
(y - 2) = 5.(x - 0)
y - 2 = 5x
y = 5x + 2
So, this is the line in slope-intercept form.
