What is the unit rate in miles per hour for each runner?

how long will each person take to run a total of 50 miles at the given rates?

sandra runs at a rate of 8 miles in 45 minutes. how does her unit rate compare to terrance's and jesse's?

Just tell me how to set up the equation.

Needmax 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.

Solve each quadratic equation by factoring and using the zero product property. [tex]x^2+6x+8=0[/tex]
