Which of the following is not a rule when writing a hypothesis

The question is incomplete, the complete question is;

Which of the following is NOT a rule when writing a hypothesis?

It is testable

It is an if/then statement

it should restate the question

It is a prediction.

The correct answer is; "It is a prediction".

A hypothesis is an explanation that framed from the research question.

Hypothesis is obtained from the research question by turning the question into a statement. In that case, we can regard it as a restatement of the question.

A hypothesis is usually written in the if/then format and it has to be testable.

A hypothesis is not a prediction rather it is based on explanation.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
