X-3=4x-9
X=4x-9+3
X=4x-6
X+6=4x |-x
6=3x |:3
X=2
Theoretical probability is what you would expect the result of an experiment would be. For example if you tossed a fair coin 10 times the theoretical result would be 5 heads and 5 tails, because probabilty of 1 toss is 1/2 for tailand 11/2 for a head.
I practice however we might get , say, 6 heads and 4 tails
So experimental probability of e head would be 6/10 and of a tail would be 4/10.
Answer:
125%
Step-by-step explanation:
to find the percentage you divide 55 by 44 which is 1.25, you multiply 1.25 by 100 to get the percentage.
X=27 because all the angles inside a triangle add up to 180°. So you take 180 and subtract 63 and 90 from the to find out the last/missing angle.
