- The average reading score of 16-year-olds on certain tests is given by y=0.195x+244.09 points, where x is the number of years after 1970. Assuming that this model was valid, write and solve an inequality that describes when the average 16-year-old's reading score on this test was between but not including 246 and 249. Between the years ___ and ____ the average 16-year-old's reading score was between but did not include 246 and 249.[4,9] how would I express this as an inequality involving x? I thought I know i thought it would be 4 is equal to or greater than x which is equal to or less than 9.A poll found that a particular group of people read an average of 10.2 books per year. The pollsters are 99% confident that the result from this poll is off by fewer than 1.39 books from the actual average x. Express this situation as an inequality involving absolute value, and solve the inequality for x to determine the interval in which the average is likely to fall. Express the situation as an inequality involving absolute value.
