Renald completed only one trial of his experiment. what effect will this most likely have?

the results are more likely to have errors.
the results are more likely to be precise.
the experiment will be harder to replicate.
the experiment will be easier to replicate.

Option (d) is the correct answer.

Explanation:

Since Renald has completed one trial of his experiment. So, now he will have an exact idea that in order to again verify his results how he should perform it such that it will consume less time.

Therefore, we can conclude that effect that will most likely have is that the experiment will be easier to replicate.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
