A rational consumer spends all of her income on two goods apple and banana suppose the last dollar spent on Appel increase her total utility from 60 units to 29 utils if the price of a unit of Appel is 2 birr what is the price of a unit of banana at equilibrium?

Answers

Answer: A rational consumer spends all of her income on two goods: Apple and Banana. Suppose the last dollar spent on Apple increased her total utility from 60 utils to 29 utils and the last dollar spent on Banana increased her total utility from 29 utils to 2 utils. If the price of a unit of Apple is 2 Birr, what is the price of a unit of Banana at equilibrium?

Explanation:

Let Apple be 'x' and banana be 'y'

Increase in apple utility divided by increase in banana utility is equal to unit price of apple divided by that of banana at equilibrium

MU(x) / MU(y) = P(x) / P(y)

(60 - 29) / (29 - 2) = 2/P(b)

31/27 = 2/P(b)

5/3 = 2/P(b)

P(b) = 0.83

So the price of one unit of banana at equilibrium is 0.83 Birr

How do you find the multicollinearity of an independent variable?

Answers

The degree to that which variables are interrelated is referred to as multicollinearity. There is multicollinearity when there exists a correlation between two independent variables.

A combination of two or more variables and one outcome variable is correlated. Researchers evaluate regression coefficients as part of linear regression to gauge the relative importance of independent variables. They examine the size of the coefficients and assess their statistical significance. Researchers determine that a variable contributes to the regression equation's predictive power if its coefficient is significantly more than zero. This makes it feasible to separate out the factors that are more and less beneficial for prediction. Plotting the correlation matrix of each independent variable is the first straightforward technique. The pairwise relationship between all the variables may be seen after visualizing the correlation matrix and color-scaling the background . The Variance Inflation Factor for each independent variable is used as the second way to test for multi-collinearity. In the set of several regression variables, it is a measure of multicollinearity. The greater the correlation between a variable and the others, the higher its value in VIF.

Through social interactions and the use of cultural tools, children learn to think and reason, internalize cultural knowledge, and develop new cognitive abilities and levels of development.

Vygotsky believed that cognitive development is a social process that is mediated by cultural tools, meaning that children learn to think and reason through their interactions with other people who possess knowledge and skills that are beyond their current level of development.

3 Differences between Intercontinental migration and Intra-continental migration​

Answers

Intercontinental migration and intra-continental migration are two different types of migration patterns. The main differences between them are:

Geographical scope: Intercontinental migration refers to the movement of people from one continent to another, while intra-continental migration refers to the movement of people within the same continent.
Distance and duration: Intercontinental migration typically involves longer distances and takes more time than intra-continental migration. Intercontinental migrants may move thousands of miles and take months or even years to reach their destination. In contrast, intra-continental migrants may only move a few hundred miles and may arrive at their destination in a matter of days.
Cultural differences: Intercontinental migrants often face greater cultural differences and may struggle to adapt to a new way of life, compared to intra-continental migrants who are more likely to find cultural similarities in their new location.
It is important to note that both intercontinental and intra-continental migration can have a significant impact on individuals, families, communities, and societies. The reasons for migration, such as economic opportunities, family reunification, political instability, or natural disasters, are also similar regardless of the geographical scope.
1. Intercontinental migration involves migration between two different continents, while intra-continental migration involves migration within a single continent.

2. Intercontinental migration typically involves longer distances and higher expenses than intra-continental migration.

3. Intercontinental migration typically involves a greater degree of cultural and language differences when compared to intra-continental migration.

Retroactive interference occurs when new learning interferes with old learning. Forgetting can occur as a result of decay, failure to reinsert the context of initial learning, or interference. Proactive interference (new learning interferes with old) is contrasted with retroactive interference (new learning interferes with old) (old interferes with new). Interference increases as the learning conditions become more similar.

Individuals learn to associate word pairs consisting of a stimulus and a target in paired-associate learning, for example (e.g., desk-sky, or A–B). A second learning trial that introduces new targets to the original stimulus words (e.g., desk-plate or A-C) results in impaired recall of the original A-B pairs when compared to a control condition in which A-B learning is followed by rest or pairs with different stimulus words (C–D).

In order to boost the British economy, a number of British regulations known as the Navigation Acts were created in the 17th and 18th centuries and governed colonial trade. These laws levied charges on some colonial products, prohibited trade with other nations, and mandated that certain goods could only be delivered on British ships. These deeds were done in order to strengthen British authority and wealth at the expense of the colonies.

A tax was levied on sugar and other items brought into the American colonies under a 1764 British law known as the Sugar Act. Instead of pursuing any mercantilist objectives, this measure was intended to generate money to pay off British war debts. Yet, similar to other previous British levies against the colonies.
