First, we get the z-score using formula:
z =( X - μ ) / σ
From the problem, we substitute the given values:
z = (9 - 7.8) / 1.7
z = 0.71
From the z-table (one-tailed), for a z-score of 0.7059, the proportion of numbers that are greater than 9 is 0.76.
Rhombus -> 2 equivalent obtuse angles, 2 equivalent acute angles
vs.
Rectangle -> 4 equivalent right angles.
