The steps below show the incomplete solution to find the value of m for the equation 4m − 2m + 4 = −1 + 13:

step 1: 4m − 2m + 4 = −1 + 13
step 2: 4m − 2m + 4 = 12
step 3: 2m + 4 = 12

which of these is most likely the next step?

2m = 3
2m = 8
2m = 16
2m = 18

Write two subtraction equations that are equivalent to 5 + 12 = 17.

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.
