Answer:
7.415 ≤ x < 7.425
Step-by-step explanation:
The number x was rounded to 2 decimal places to give 7.42.
Since rounded off to 2 decimal places, the error interval for x is half of 0.01 subtracted from and added to 7.42.
Thus;
7.42 ± (0.01/2)
(7.42 - 0.005),(7.42 + 0.005)
7.415, 7.425
Now, 7.425 will not be included in the internal because approximating it doesn't give 7.42.
Thus,the error interval is;
7.415 ≤ x < 7.425
Answer:
This is the most hardest question I have seen but I think it may probably be 25
Step-by-step explanation:
The question is not exhaustive.
no of members who voted=
75/100x60=45members
no of members who did not vote=
60-45=15 members
26.80 x .15 gives you the answer, which is $4.02 in tip
