Answer: simple random sampling

Step-by-step explanation:

  • A simple random sampling is a sampling technique in statistics in which a subset of the population (with population size N) is drawn by the researcher by selecting candidates for sample randomly such that the chances for each candidate to get selected remains equal as \dfrac{1}{N}.

Given : The names of 50 contestants are written on 50 cards.

here ,N= 50

So , the probability for each student to get selected =  \dfrac{1}{50}.

The cards are placed in a bag, and three names are picked from the bag (which is a random action).

Hence, the sampling technique is used is "simple random sampling" .

Luden [163]

Answer:

The percentage increase of the area of the building space is 33%.

Step-by-step explanation:

We are given the following in the question:

Original area of company = 17,000 square feet

Expanded area of company = 22,610 square feet

We have to calculate the percentage increase of the area of the building space.

Increase percentage =

=\dfrac{\text{Increase}}{\text{Original}}\times 100\%

Putting values, we get,

=\dfrac{22610-17000}{17000}\times 100\%\\\\=\dfrac{5610}{17000}\times 100\%\\\\=33\%

Thus, the percentage increase of the area of the building space is 33%.
