The most appropriate word among the group of answer choices to fill in the blank is: a. Random sample surveys.

Sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

The various types of sampling used by researchers includes the following;

  • Systematic sampling.
  • Convenience sampling.
  • Stratified sampling.
  • Cluster sampling.
  • Random sampling.

A random sample survey is also referred to as a simple random sample (SRS) and it can be defined as a sampling technique that involves randomly selecting a subset of a larger population. Also, any result obtained through the use of a random sample survey can be generalized and applied to a larger population.

In conclusion, scientists and researchers prefer random sample surveys because their results can be generalized to a larger population.

Determine the kinetic energy of an 833.0 kg roller coaster car moving at a speed of 20.0 m/s
trasher [3.6K]

Answer:

166,600J

Explanation:

Kinetic energy (K.E), which is the energy due to motion of a body, can be calculated by using the formula;

K.E = 1/2 × m × v²

Where;

K.E = kinetic energy (joules)

m = mass of body (kg)

v = speed or velocity (m/s)

According to this question, the mass of the roller coaster is 833.0 kg while its velocity/speed is 20.0m/s.

K.E = 1/2 × 833 × 20²

K.E = 1/2 × 833 × 400

K.E = 1/2 × 333200

K.E = 166,600

Therefore, the kinetic energy of the roller coaster car is 166,600J.
