Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted: rectangle with a length of x plus 15 and width of x plus 10 with a rectangle in the bottom right corner labeled bench that has a length of 5 and width of 1 Write an equation to determine the area, A, of the patio that will be painted.

A = (x + 20)(x + 11)

A = (x + 15)(x + 10) + 5

A = (x + 15)(x + 10) − 5

A = (x + 9)(x + 10)

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

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.

How many times larger is 6 × 10^12 than 2 × 10^7? a. 30,000 b. 3,000 c. 3,000,000 d. 300,000
