I cut a piece of rope into four segments. Segment 1= 0.75 cm
Segment 2= 2.278
Segment 3= 6.11
Segment 4= 6.72

Find the following:
i) Sum of all segments
ii) Sum of first two segments
iii) Sum of last two segments
iv) How much longer is the sum of 3rd and 4th Segment than Sum of 1st and 2nd Segment?

What number should be added to both sides of the equation to complete this square? x^2-10x=7

What is the binomial expansion of (2x-3)^5

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.
