Hal makes an error when determining the difference quotient of f(x) = x2 + 11x + 2. His work is shown. StartFraction ( (x + h) squared + 11 (x + h) + 2) minus (x squared + 11 x + 2) Over h EndFraction. StartFraction x squared + h squared + 11 x + 11 h + 2 minus x squared minus 11 x minus 2 Over h EndFraction. StartFraction h squared + 11 h Over h EndFraction. h + 11. Which statement describes the error? He did not expand (x + h)2 correctly. He did not combine like terms correctly. He should have subtracted f(x) β f(x + h), not f(x + h) β f(x). He should have added f(x + h) + f(x), not subtracted f(x + h) β f(x).

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about maxβs data must be true? a. the median of maxβs data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
