Find the total charge on a circular disk defined by r ≤ a and z = 0 if:a)rhos= rhoso cos(φ) (C/m2) b)rhos= rhoso sin2(φ) (C/m2) c)rhos= rhoso e−r (C/m2) d)rhos= rhoso e−r sin2(φ) (C/m2) where rhoso is a constant.

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

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 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.
