Option c is correct. The best description of the pattern of Swedish American ethnicity is that there is a a Swedish ethnic majority in the northern half of the state.
This question involves a map so to answer it one must take a close look at the map. The map is made up of black, grey and white areas.
The answer to this question can be seen in the <u>black area</u>. This part has the most percentage of about 15% to 25%.
The Northern part of the map is the at the top of the map. Therefore we conclude that the majority of 15 to 25 percent are in the Northern half of the state.

A radioactive element with a half-life of 1,000 years, and starting mass of 20 grams, will need 2,000 years to decrease to 5 grams.
Explanation:
The radioactive elements all have a specific half-life. Each element's half-life is well known, and they are used by scientists of numerous fields as they are excellent for determining the age of a particular item, be it or organic or non-organic nature. In this case, we have a radioactive element with a half-life of 1,000 years, and starting mass of 20 grams.
The half-life basically means that half of the mass of an element is lost during a particular period of time. For the element in question we need to find out how much time will be needed for it to decrease to 5 grams. In order to get to the result, we just need to add 1,000 years on every decrease of half of the mass:
20/2 = 10
10/2 = 5
So in 1,000 years, the element in question will decrease to 10 grams, and in further 1,000 years (2,000 cumulatively) it will decrease to 5 grams.

To be classified as a hurricane a typical Cyclone must have a maximum sustained winds at least 74 mph.
Answer:
The K-T extinction event is the global mass extinction that has taken place about some 65 million years back due to the asteroidal impact. This mass extinction event has wiped almost 75% of the plants and animal species from the earth's surface. The dinosaurs were extinct and very animal species have survived and undergone evolution in due course of time.|
The Cenozoic era started after the K-T mass extinction event, i.e from about 65 million years to the present.
Thus, the Cenozoic era is also known as the age of mammals because mammal were more abundant and diverse then. Many flowering plants evolved during this time and the earth experienced global cooling.
