The moon forms a right triangle with the earth and the sun during one of its phases as shown below

a scientist measures the angle x and the distance y between the sun in the moon using complete sentences explain how the scientist can use only these two measurements to calculate the distance between the earth and the moon.

Solve the system of equations. y= 2x y= x^2 - 15

[15 points]find the quotient with the restrictions. (x^2 - 2x - 3) (x^2 + 4x + 3) ÷ (x^2 + 2x - 8) (x^2 + 6x + 8)

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.
