farmer grows tomato plants in a 1,200 sq ft greenhouse. The greenhouse can support growth for 3 tomato plants per sq ft. Each tomato plant yields 18 lbs of crop per year and the farmer sells his tomatoes at the local farmers market for $2.50 / lb. If the farmer has $10 of costs growing each tomato plant, what is his potential annual net profit from his tomato plants?

Me 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.

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 + 4x + 5 = 0
