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

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
