Let us say T= probability of head turning up = 1/2 in one toss
H = probability of a tail turning up = 1/2 in one toss
Then P (56 heads or more) =
1/2^100 [ C(100,56) + C(100,57) + C(100,58) + ....
C(100,98) + C(100,99) + C(100,100) ]
where C(N, R) = N ! / [ (N - R)! R! ] number of occurrances of R formed from
N tosses.
Answer:
Step-by-step explanation:
hello :
(3+i)(2+i) = 6+3i+2i+i² but : i² = -1
(3+i)(2+i) = 5+5i
Using th epythagorean theorem.
52^2-48^2= x^2
2704-2304= x^2
400=x^2
x=20
Final answer: D
Answer:
x = 
Step-by-step explanation:
Using the rule of exponents
= 
Note that 8 = 2³ and 2 = 
, then
= , that is
=
Since the bases on both sides are equal, equate the exponents
3x = 1 ( divide both sides by 3 )
x =
The correct answer is B.
Find the slope using the formula m= y2-y1 / x2-x1. You will get 11.50/2, which is p = $5.75 per hour.
