Problem number 26 of the Rhind Papyrus says: Find a quantity such that when it is added to StartFraction 1 Over 4 EndFraction of itself the result is a 15.

The modern day equation that models this problem is x plus StartFraction 1 over 4 EndFraction x equals 15..

What is the solution to the equation?

x = 10
x = 12
x = 15
x = 30

Ihave trouble finding the nth term of a linear sequence

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1

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.
