Which of these is not a characteristic of science?.
Degger [83]

Science is not testable is not a characteristic of science.

The omitted options include :

  • science is a process.
  • science is a body of knowledge.
  • science must follow the scientific method.
  • science is not testable.

<h3>What is a Scientific method? </h3>

A scientific method refers to the step  by step process that   scientists must follow in order to give scientific explanation of a phenomena or invention of an idea that is testable.

The scientific method includes:

  • Observation
  • Constructing  a hypothesis/ testable explanation
  • Conducting experiments to test the hpothesis
  • Formulation of theories based on experiments
  • Conducting further experiments and research
  • Making conclusions/Formulation of laws.
  • Reporting, and evaluating.

Thus, the characteristics of science include:

  • science is a process.
  • science is a body of knowledge.
  • science must follow the scientific method.

Therefore it is wrong to say that science is not testable.

A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expense
djverab [1.8K]

Answer:

C. 4.29 years

Explanation:

The computation of the payback period is shown below:

Payback period = Initial investment of the equipment ÷ Cash flows

where,

Initial investment = $30,000

And, the cash flows is

= $8,500 - $1,500

= $7,000

So the payback period is

= $30,000 ÷ $7,000

= 4.29 years

By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.
