The radius of a cone-shaped tank is 4 feet less than its height. if the height of the tank is (x - 3) feet, the expression below shows the volume of the tank.

1 over 3_ (x - 7)2 (x - 3)

what does the factor 1 over 3(x - 7) represent?

the total surface area of the tank

one third of the radius of the tank

one third of the height of the tank

the total area of the base of the tank

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.

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
