Object permanence involves understanding that something exists even when it is out of our sensory awareness.

navik [9.2K]

That statement is true.

Object permanence is a very important step in a child development. It requires the capability to create a mental representation about that specific object.
This very development make the children understand that their parents do not actually disappear when they're playing a peek-a-boo

Why would a person want to be part of a secondary group? to accomplish a specific goal, such as graduating from college to have

sp2606 [1]

Answer:

to accomplish a specific goal, such as graduating from college.

Explanation:

In sociology, a group is an association of two or more people who gather together for a number of common interests, shared identity, or any other reason, and that identify themselves as belong to said group. There are two types of groups: primary and secondary groups. Primary groups are those where the bonds between the members of the group are closer, longer lasting, more intimate, and more emotionally important. Family and close friends are the prime examples of primary groups. Secondary groups, on the other hand, are larger than primary ones, and their members come together because of a shared goal or interest. <u>People usually join these groups to accomplish a specific goal, such as graduating from college</u>. School and work groups are common examples of secondary groups. While these groups are often impersonal, strong bonds can develop between some members of a secondary group and develop into a primary group.

A budget is simply an estimate of income and expenses for a set period of time with designated categories. To get started in creating one; make a list of all your sources of income for the month (take-home pay). Then list all your expenses for the month—start with the four walls (food, shelter and utilities, transportation and clothing). You want to make sure your rent or mortgage is budgeted for first before you start budgeting for your gym membership. Once that’s taken care of, list all your other expenses, like entertainment, date nights, and the shoes little Johnny needs for school. Some expenses will occur every month (rent, utilities), and some will be one-time expenses (birthday gifts, special events, weddings). Adjust your budget each month and you’ll be set.

An industry has 5 firms, and is found to have violated antitrust laws. The government breaks it up into 10 firms that will share

Andrew [12]

Answer:

2,000 to 1,000

Explanation:

The Herfindahl-Hirschman Index, HHI, is measured by using the market share of each firm in the industry, then square them, and sum the result.

However, supposing that there were only one firm in an industry, that firm would have 100% market share, and the Herfindahl-Hirschman Index (HHI) would equal 10,000, indicating a monopoly.

Thus, in this case, it was initially 5 firms, with no special market share allocated to each of the firm, hence, it is assumed they shared the market share equally, and that will be 2,000 HHI. This shown by each of the 5 firms having 20% market share

HHI = 20² + 20² + 20² + 20² + 20² = 2,000

At the same time, since the government breaks the industry up into 10 firms that will share the market equally. Then, the Herfindahl index will be 1,000. This is shown by HHI = 10² * 10 (since it involves 10 firms with equal share of the market) = 1,000.

Therefore, The Herfindahl index for the industry would change from: 2,000 to 1,000.
