We are to find for the probability when X≤400 or X≥500
We use the z score formula: z = (x – u) / s
when X≤400, the z is:
z = (400 – 500) / 100 = - 1
when X≥500, the z is:
z = (500 – 500) / 100 = 0
SO from the standard probability tables, the probability
at:
<span>P (z ≤ -1 or z ≥ 0) = 0.6587</span>
V would be 72
you need to multiple 3, 4, and 6.
doing it in separate steps could be easier
3 x 4 is 12. then 12 x 6 is 72
or if u have a calculator, just punch 3 x 4 x 6 which should give you 72
Answer:
88
Step-by-step explanation:
Angle Formed by Two Chords = 1/2( sum of Intercepted Arcs)
ABD = 1/2 ( 131+ 53)
ABD = 1/2 (184)
=92
We know that ABC + ABD form a straight line
ABC = 180 -ABD
ABC = 180 -92
ABC = 88
