Answer:
12
Step-by-step explanation:
divide 90 by 3 then take that and divide it by 5 then multiply that by 3 then subtract that from the answer of 90 divide by 3
12.41 less than the product of 42 and x
= 42x - 12.41
Answer:
C) 2,2,2.82842712
Step-by-step explanation:
Answer:
Cluster sampling.
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
People divided into groups, by households.
Each member of the households(group) is surveyed, so cluster sampling.
Solution :
Nuclear fission is exponential. With uranium atoms arranged properly it is possible to have the fission effect and cause more and more uranium nuclei to fission. This is known as chain reaction and a number of uranium atoms are fission together to increase exponentially.
Canada, for example produces electricity using the process of fission process in its nuclear reactors.
But one of the problems with nuclear reactors is its disposal of the nuclear waste. The nuclear waste includes the used reactor fuel, uranium mill tailings and other radioactive wastes. They remain radioactive and are dangerous for the human health.
A). The long term nuclear waste are stored in deep excavations and covered with rocks and mud so that the harmful radioactive materials does not escape from them. They are also stored in some high density and thick cylinders and remained isolated in the dump yard from the people and nature.
B). Canada has a high source of renewable sources of energy. This is a clean source of energy and Canada can make best use of it. Most of the energy requirement of Canada can be taken care off by using wind energy. Canada is planning to set up wind energy mills in most of its part and generate electricity from it.
Canada has also installed several solar power projects which is clean and can help the people to use this solar energy to produce electricity.
