One group of scientists (group a) has measured a time for a particular chemical reaction to be completed to be 7.34 ± 0.05 s. a second group of scientists (group b) complete a similar experiment and measure the time to be 7.38 ± 0.03s. a third group (group c) measured the time to be 7.46 ±0.06s. do results of group a and b agree with each other within the experimental uncertainty? do results of group a and c agree with each other within the experimental uncertainty?

1. Group A and B agree with each other.

2. Group A and C do not agree with each other.

Step-by-step explanation:

When we are analizing this problem, we will see what are the ranges of this measured times. Since we are taking into account the error we can see that :

Question 1 is about the overlapping response in Group A and Group B. And yes, we have an overlap between 7.35 to 7.39. Among this times both group A and B are in agree with each other within the experimental uncertainty.

Question 2 is now referring to Group A and Group C. And no, there isn't any common time where both groups agree with each other.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

i will pick c put check it over to be sure
