Write any two quadratic equations​.
Thepotemich [5.8K]

To find:

Any two quadratic equations​.

Solution:

The general form of a quadratic equation is:

ax^2+bx+c=0

Where, a,b and c are real number and a is non zero.

We know that a,b,c can take any values but a cannot be 0.

For a=1, b=1,c=1, we get

1x^2+1x+1=0

x^2+x+1=0

One quadratic equation is x^2+x+1=0.

For a=3,b=-1,c=5, we get

3x^2+(-1)x+5=0

3x^2-x+5=0

Therefore, the two quadratic equations are x^2+x+1=0 and 3x^2-x+5=0.

The spread around a regression modle is measured with the residual standard deviation. True or False
Anna11 [10]

Answer:

True

Step-by-step explanation:

Residual standard deviation is the square root of the residual variance. It is an estimate of the error made on the measurement of the dependent variable.

Thus, the spread around the regression model is usually measured with the residual standard deviation because it is the measurement of standard error between actual and predicted value.
