520 CD's because of the 9 months and we add 30 time 9 we erase the 0 and multiply the 3 with the 9 it will be 27 right we add the zero because the originla number is 30
Answer:
(x-6) (2x+1)
Step-by-step explanation:
1) move everything over to the left side, so subtract 11x and 6.
2x^2 -11x - 6 = 0
2)multiply 2(a term) with -6 (c term)
x^2 -11x -12
3) factor and find what multiples to -12 and adds up to -11. in this case its -12 and positive 1
(x-12) (x+1)
4) divide -12 and 1 by the original a term (2)
(x-6) (x+1/2)
5) move the denominator of 2 over to the x.
(x-6) (2x+1)
Answer:
probability of getting four head consecutively is 0.2
Step-by-step explanation:
in an experiment coin is flipped 4 times.
given, coin landed heads up more than two times
outcomes of coin landed heads up more than two times =
SAMPLE SPACE : [ {HHHT}{HHTH}{HTHH}{THHH}{HHHH} ]
chance of getting 4 heads = 1 (HHHH)
Probability = 
hence the probability of getting four head consecutively is 0.2
