Gordon bower believed that: a) learning is a gradual, incremental process. b) it is important to look at the average of learning scores. c) learning can be explained by a mathematical model. d) all of the answers are correct.

C  

Explanation:

Learning can be explained by a mathematical model. Gordon Bower was a psychologist who works om memory. He was a cognitive psychologist who studies human memory, language, emotions, and behavior. He has taken interest in cognitive process and emotions, imagination , language and reading comprehension as they relate to the memory. His main focus was on the mathematical model of memory. one of the models he explained was about the concepts. He shifted him focused towards short term memory. A particular 7 items digit was given by Bower that is still popular as chunking.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7
