The interval in which the average is likely to fall :
Step-by-step explanation:
Given : A poll found that a particular group of people read an average of 12.8 books per year.
The pollsters are 99% confident that the result from this poll is off by fewer than 3.93 books from the actual average x.
The inequality to express this situation involving absolute value will be :-
Hence, the interval in which the average is likely to fall :
Answer:
an enlargement or a reduction of the figure
a slide of the figure

Answer:
1440
Step-by-step explanation:
Let's say x = number of hours worked per week for 12 people. Now one worker works 30 hours a week so if you multiply 12 workers by 30 you will get how many hours 12 workers worked. so x = 12 • 30. 12 • 30 is 360. so x = 360 or for 1 week 12 workers worked 360 hours. now we need to find the amount of hours for 4 weeks. so we can do 4x or 4 times the amount of hours per one week. since x = 360. 4 • 360 = 1440.
