Hi! I'm on my sisters account, and we are trying to do a challenge, so can you please help me!

The diagonals of a rhombus are 12 inch and 16 inch long, the length of a side of a rhombus is 10 inch, what is the height of the rhombus

Choose the correct slope of the line that passes through the points (1, -3) and (3, -5)

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.
