Answer:

placebo

Explanation:

We often hear about placebos being used in pharmacological tests. A placebo is an inert substance, sometimes called a "sugar pill," which can be given in place of the drug being evaluated.

Scientists commonly use placebos to study the effects of a new drug. This is done by providing the drug to a number of people who participate in the trial, while the rest receive another substance that lacks medical or therapeutic properties.  Test participants do not know if they received the placebo or the actual drug. Often, even doctors know which participants ingest the drug and which not until the end of the pharmacological test.

Sue views hot dogs and hot dog buns as perfect complements in her consumption, and the corners of her indifference curves follow
kogti [31]

Answer:

6 packages of hot dogs and 6 packages of buns

Explanation:

The indifference curves follow the 45-degree so the ratio for the hot dog:bun will be 1:1. Each package of hot dog gives 8 hot dogs while each package of the bun gives 8 hot dog buns. The ratio of hot dog package: buns package that Sue needs will be:

(number of hot dogs every package)/ (number of buns every package) * (ratio of hot dog : bun)

8/8 * 1/1= 1

The optimal choice package ratio is 1:1, then the amount of food Sue can buy will be: 48$/ (1*$5 + 1*$3)= $48/$8= 6 package.

The optimal choice is 6 packages of hot dogs and 6 packages of buns

zvonat [6]

Answer:    A failure to earn social reinforcement associated with an "A".

Explanation:  According to reinforcement theory, which is an integral part of behavioral theory, it argues that social behaviors are conditioned by external events. Such external events are outside the human psyche, so they absolutely come as an external factor, and people repeat certain behavior if accompanied by some external reinforcement that is pleasant, in Leslie's case it is usually A in tests. Such external factors, events, imply the removal of something unpleasant, that is, aversive, but if this happens, then there is a decline in the acquisition of pleasant reinforcements, the consequence can be depression.
