Such information is valid when A. it is not biased.
There is no bias in science - the results are either correct or incorrect; personal opinions have nothing to do with that. B is incorrect because the point of experiments is that they can be repeated to achieve the same results. C and D are likewise incorrect as primary sources are important, and you can share the results with others if you want to.

Answer:

a. it is not biased

Explanation:

Scientific information can not be biased to be credible and valid, and it is only possible to be sure that this scientific information is true if the results are repeated in different types of experiments and tests. We can not forget that scientific information gains credibility with primary sources that give scientific background to the statements, moreover, the purpose of formulating scientific information is to share information and let everyone know about it.

The function s(t) represents the position of an object at time t moving along a line. Suppose s (2 )equals 146and s (6 )equals

sineoko [7]

Answer:

v(t) = 27 units

Explanation:

The function s(t) represents the position of an object at time t moving along a line such that,

$s(2)=146$

and

$s(6)=254$

We need to find the average velocity of the object over the interval of time [2,6]. The velocity of the object is equal to the total distance divided by time. It is given by :

$v(t)=\dfrac{s(6)-s(2)}{6-2}$
