g Define simple random sampling. Choose the correct answer below. A. Simple random sampling is the process of obtaining a sample
swat32

Answer:

C. A sample of size n from a population of size N is obtained through simple random sampling if every possible sample of size n has an equally likely chance of occurring. The sample is then called a simple random sample.

Step-by-step explanation:

Simple Random Sampling is the sampling where samples are chosen randomly, where each unit has an equal chance of being selected in a sample.

Option A is incorrect as the size of the sample and size of the population is not the same generally if it does happen then there will be no difference between sample and population.

Option B is incorrect as Simple Random Sampling is not a chance it is a way that samples can be taken.

Option D is incorrect as when samples are taken using a convenient sample then it is called Convenient Sample, not Simple Random Sample.

Thus, only option C is correct.

At a hockey game a vendor sold a combined total of 110 sodas and hot dogs. The number of hot dogs sold was 42 less than the numb
jasenka [17]

76 sodas and 34 hot dogs were sold by the vendor.

Step-by-step explanation:

Given,

Total sodas and hot dogs sold = 110

Let,

x be the number of sodas sold

y be the number of hot dogs sold

According to given statement;

x+y=110     Eqn 1

y = x-42    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x+(x-42)=110\\x+x-42=110\\2x=110+42\\2x=152

Dividing both sides by 2

\frac{2x}{2}=\frac{152}{2}\\x=76

Putting x=76 in Eqn 1

y=76-42\\y=34

76 sodas and 34 hot dogs were sold by the vendor.
