Answer:
The objective function is to minimize cost thru use of linear programming
Explanation:
A craftsman named William Barnes builds two kinds of birdhouses, one for wrens and a second for bluebirds. Each wren birdhouse takes 4 hours of labor and 4 units of lumber. Each bluebird house requires 2 hours of labor and 12 units of lumber. The craftsman has available 72 hours of labor and 120 units of lumber. Wren houses yield a profit of $ 10 each and bluebird houses yield a profit of $ 15 each. The aim of the objective function for William should be to ▼ Minimize Maximize the objective value.
The objective function is to minimize cost thru use of linear programming
Answer:
60 pizzas
40 pizzas
Explanation:
Marginal product measures the change in output as a result of a change in input by one unit
Marginal product = change in output / change in input
Marginal product for the 4th worker
Change in output = 360 - 300 = 60 pizzas
Change in input = 4 - 3 = 1 worker
Marginal product = 60 / 1 = 60
Marginal product for the 5th worker
Change in output = 400 - 360 = 40 pizzas
Change in input = 5 - 4 = 1
Marginal product = 40 / 1 = 40
It can be seen that marginal product decreased from 60 to 40 when the 5th worker was added. This illustrates diminishing marginal returns.
The law of diminishing returns says as more units of a variable input is added to a fixed income of production, output might increase at a point but after some time total output would increase at a decreasing rate and marginal product would be decreasing.

Self-confidence is considered one of the most influential motivators and regulators of behavior in people's everyday lives (Bandura, 1986). A growing body of evidence suggests that one's perception of ability or self-confidence is the central mediating construct of achievement strivings (e.g., Bandura, 1977; Ericsson et al., 1993; Harter, 1978; Kuhl, 1992; Nicholls, 1984). Ericsson and his colleagues have taken the position that the major influence in the acquisition of expert performance is the confidence and motivation to persist in deliberate practice for a minimum of 10 years.
Self-confidence is not a motivational perspective by itself. It is a judgment about capabilities for accomplishment of some goal, and, therefore, must be considered within a broader conceptualization of motivation that provides the goal context. Kanfer (1990a) provides an example of one cognitively based framework of motivation for such a discussion. She suggests that motivation is composed of two components: goal choice and self-regulation. Self-regulation, in turn, consists of three related sets of activities: self-monitoring, self-evaluation, and self-reactions. Self-monitoring provides information about current performance, which is then evaluated by comparing that performance with one's goal. The comparison between performance and goal results in two distinct types of self-reactions: self-satisfaction or -dissatisfaction and self-confidence expectations. Satisfaction or dissatisfaction is an affective response to past actions; self-confidence expectations are judgments about one's future capabilities to attain one's goal. This framework allows a discussion of self-confidence as it relates to a number of motivational processes, including setting goals and causal attributions.
