Answer:
We are 85% confident that the proportion of adults who dreaded valentines day is within the range of 8.8% to 21.2%.
Step-by-step explanation:
Proportion of adults who dreaded valentines day = 15% = 0.15
The margin of error with 85% confidence = 6.2% = 0.062
The confidence interval is given by
p ± margin of error
0.15 ± 0.062
Lower limit = 0.15 - 0.062
Lower limit = 0.088
Lower limit = 8.8%
Upper limit = 0.15 + 0.062
Upper limit = 0.212
Upper limit = 21.2%
So it means that we are 85% confident that the proportion of adults who dreaded valentines day is within the range of 8.8% to 21.2%.

The answer to the question is B. 8
Answer:
Distance between Exeter and the point where flat tire occurred was 1.875 miles.
Step-by-step explanation:
Let the distance of Exeter and the point where bike developed the flat tire was = x miles
Then time taken to reach that point with speed 15 mi per hour = 
=
hours
Devon comes back with a speed of 3 miles per hour then time taken to come back =
hours
Total time for the entire episode = 48 minutes or
hours
Therefore, 


x = 
x =
miles
x = 1.875 miles
Therefore, distance between Exeter and the point where flat tire occurred was 1.875 miles.
2. There are 18 other bottles in the fridge, because .6 of 30 is 18. 30 – 18 is 12, so there are 12 bottles of orange juice and cranberry juice.
4. If the probability of an event is 25%, then the probability of <em>not</em> that event is the other part of 100%. In other words, 1 – .25 = .75.
