Which of the following are qualities of any good scientific hypothesis? i. it is testable. ii. it is falsifiable. iii. it produces quantitative data. iv. it produces results that can be replicated.

(1) Testable

(11) Falsifiable

Step-by-step explanation:

An idea that presents a provisional explanation about a phenomenon observed by  a researcher.

The main features of a scientific hypothesis are : testability and falsifiability

A testable hypothesis should answer the scientific question.This is one that can be checked true or false using the data collected or the experience gained.

Falsifiability is the capacity of a theory to be proven wrong.It normally appears in the null hypothesis statement which presents an opposite view of the experimental /alternative hypothesis.Null hypothesis presents what the results will mean in case what is predicted in the hypothesis is not supported by study.

C.

to compare the results when the independent variable is not involved

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
