where ln(.) is the natural logarithm. The rationale for this formula is that ln(L0) plays a role analogous to the residual sum of squares in linear regression. Consequently, this formula corresponds to a proportional reduction in “error variance”. It’s sometimes referred to as a “pseudo...
In the operant conditioning model, learning occurs as behaviors receive rewards and punishments. A reward is something which increases the likelihood of a behavior. A punishment is something that decreases the likelihood of a behavior. Answer and Explanation: ...
The discriminant of the quadratic formula (b2 - 4ac) appears under a square root sign and, even before the equation is solved for x, can indicate the type and number of solutions found. The type of solution depends on whether the discriminant is equal to the square root of a positive or...
Solving Quadratic Equations using the Discriminant Graphical method for solving a Quadratic Equation Let us understand these methods one by one. But, before that let us understand how to check whether a givenequationis quadratic or not? Determining whether the given Equation is Quadratic or not ...

Explain how to determine if a function is linear or quadratic.What is the value of the discriminant in the quadratic function 2x^2 - 10x - 5 = 0?What does a represent in a quadratic equation?What quadratic equation has roots 1 and 5?What is the quadratic formula?
We know that b2- 4ac is thediscriminant(D). Thus, the vertex formula is:(h, k) = (-b/2a, -D/4a)where D = b2- 4ac Formula 2 If you feel difficult to memorize the above formula, you can just remember the formula for the x-coordinate of vertex and then just substitute it in ...

by vieta’s formula, a is the sum of the integral zeros of the function, and so a is integral. because the zeros are integral, the discriminant of the function, a 2 − 8 a , is a perfect square, say k 2 . then adding 16 to both sides and completing the square yields ( a ...
