Amen’s softball league is experimenting with a yellow baseball that is easier to see during night games. one way to judge the effectiveness is to count the number of errors. in a preliminary experiment, the yellow baseball was used in 10 games and the traditional white baseball was used in another 10 games. the number of errors in each game was recorded and is listed here. can we infer that there are fewer errors on average when the yellow ball is used?

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
