Uranium-235 has a half-life of 700 million years. How many years will it take Uranium-235 to decay to 1/8 of its original mass?

Answers

Answer 1

Answer: 2.1 billion years

Explanation:

The half-life of an element refers to the amount of time it would take for half of its mass to decay.

In 700 million years, Uranium - 235 will be 1/2 of its original mass.

If divided by 2, the 1/2 becomes 1/4 which is the proportion of the original mass the Uranium would get to after another 700 million years.

Dividing by another would get the Uranium-235 to 1/8 of its original value and would take another 700 million years.

Total time taken:

= 700 + 700 + 700

= 2,100 million years

= 2.1 billion years

An assembly line produces gears for the transmissions of a Toyota sedan. This particular assembly line produces over 25,000 gears per day. To test the machine the inspector will randomly sample 1,000 gears and run a diagnostic on each. If the machine is working normally, only 2% of the gears will fail the diagnostic. On a particular inspection, 30 of 1000 gears fail the diagnostic. The inspector is worried that this is too high, is this the result significant at the 1% level?

Beliefs, opinions, and views are essentially the same things.

Answers

Answer:

Yeah, I would say that’s true

Unlike an opinion, a belief is a conviction based on cultural or personal faith, morality, or values. Statements such as "Capital punishment is legalized murder" are often called "opinions" because they express viewpoints, but they are not based on facts or other evidence.

Explain how humans communicate nonverbally. How do genders differ in terms of nonverbal communication?

Answers

Answer:

Non-verbal communication is one in which people use communicative means other than language, that is, they do not use the word and its meaning to convey a message, but rather through gestures, body expressions, movements, looks, images, etc., that is, appealing to the human senses without using language as a communication channel.

In principle, there are no major differences in how each gender communicates non-verbally with each other or with the other, except in matters of love attraction, where clothing, postures and looks play a fundamental role.

Stock Y has a beta of 1.0 and an expected return of 12.4 percent. Stock Z has a beta of 6
and an expected return of 8.2 percent.
What would the risk-free rate have to be for the two stocks to be correctly priced? (Do
not round intermediate calculations and enter your answer as a percent rounded to 2
decimal places, e.g., 32.16.)

Answers

Answer: Risk free rate = 1.9%

Explanation:

The Capital Asset Pricing Model allows for the calculation of the required return using the market return, beta and risk free rate.

Required return = Risk free rate + Beta * ( Market return - Risk free rate)

First find the market rate. Stock Y is uniquely positioned to help with that:

12.4% = Risk free rate + 1.0 * (Market return - Risk free rate)  

12.4% = rf + Market return - rf  

Market return = 12.4%

Apply this to the formula using Stock Z:

8.2% = rf + 0.6 * (12.4% - rf)  

8.2% = rf + 7.44% - 0.6rf  

rf - 0.6rf = 8.2% - 7.44%  

0.4rf = 0.76%  

rf = 0.76% / 0.4  

Risk free rate = 1.9%

How do migration patterns impact women differently? What can governments do to protect women from the negative effects of migration?

Answers

The correct answer to this open question is the following.

Although there are no options attached or specific context, we can comment on the following.

Migration patterns impact women differently because depending on their own circumstances and the country in which they live, women are exposed to many different things that affect them and their children.

For instance, in many Central American countries such as El Salvador, Nicaragua, and Honduras, men leave their homes to immigrate to the United States. Meanwhile, women stay at home with their children, living the exact same problems: poverty, hunger, disease, and lack of opportunities. So if the husband can cross the US-México border and get a decent job in the United States, that is a matter of luck and the pass of time. During that process, women have to feed and protect their children under the worst of circumstances. And that is a major issue for women.

What governments can do to protect women from the negative effects of migration is to establish a series of programs and legislation that protect women while their husbands are away trying to get a fortune in the United States, for instance. This means that the government should invest to spend some money on social programs to guarantee basic living standards for mothers and children. For example, the opportunity to access health systems and public education to their children.

Answers

Answer:

Below

Explanation:

Despite the mutual non-aggression pact, the Soviets and the Germans were not on good terms. The Nazis were against the spread of communism, and the Soviets were against Nazi ideologies. During 1939, both of these nations had their reasons for staying neutral, but once those reasons were gone, it was only a matter of time before they clashed with each other. Even while fighting in France, Hitler had his doubts about Stalin and stationed some reserve troops on the Eastern border.
