The number of patients treated at dr. mccormick’s dentist office each day for nine days is 13, 16, 16, 10, 6, 12, 4, 12, 16. find the mean, median, mode, and range of the data.

mean 11.6 or 12

median 4 (10-6)

range 12 (16-4)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
