For the function given below, find a formula for the riemann sum obtained by dividing the interval [a, b] into n equal subintervals and using the right-hand endpoint for each c subscript k. then take a limit of this sum as n right arrow infinity to calculate the area under the curve over [a, b]. f(x)equals2x over the interval [2,4].

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

Now 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 max’s data must be true? a) the median of max’s 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.

Can you me find the missing length. i attached an image.
