Look at the problem and work shown. in which line was an error made and what should have been done differently?

seven less than 5 times a number is 62. what is the number?

7 – 5n = 62 (line 1)

7 – 7 – 5n = 62 – 7 (line 2)

–5n = 55 (line 3)

–5n ÷ 5 = 55 ÷ 5 (line 4)

n = –11 (line 5)

Cor d? ? 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.

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.

The graph of f(x) is obtained by reflecting the graph of f(x)=-3|x| over the x-axis. which equation describes f(x)? a) f(x)=3|x| b) f(x)=|x+3| c) f(x)=-3|x| d) f(x) = - |x+3|
