Let X be a random variable for the Celtics score. Then you want

P(X > 101.7) 
 1 - P(X < 101.7) 
 = 1 - P((X - μ)/σ < (101.7 - 99.2)/10.5)) 
 = 1 - N_Z(0.2381)

shape ABCDEF is an irregular hexagon. prove that the sum of the shape is720 degrees. show ur working. (3marks)

Answer:

Here's one way to do it

Step-by-step explanation:

Divide the hexagon into triangles, for example, as in the diagram below.

The triangles are all inside the hexagon, so the sum of their interior angles is the sum of those of the hexagon.

The sum of the interior angles of a triangle is 180°.

There are four triangles, so

Sum of interior angles = 4 × 180° = 720°
