Solution: We are given that a fair coin is tossed three times. The sample space associated with the three tosses of fair coin is:
We have to find the probability of getting exactly one tail.
From the above sample space, we clearly see there are three outcomes which favors the probability of exactly one tail.
n( 1 tail) =
Therefore the probability of exactly one tail is
Answer:
(2x+5)(x+4)
Step-by-step explanation:
2x²+13x+20
_5_+_8_=13
_5_×_8_=(2x20)
now it can be re-written as
2x²+5x+8x+20
which can be factored to be:
(2x+5)(x+4)
Answer: C. not given
Step-by-step explanation:
formula for volume of sphere: V=(4/3)πr³
V=(4/3)πr³
V=(4/3)(3.14)(3)³
V=(4/3)(3.14)(27)
V=113 in³
1. n-3^2
2. 7-(2/n)
3. n=35+(1/2*35)+14
4. (1/n^2)-(19*n)
Answer: x=25, y=2
Step-by-step explanation:
use Pythagorean theorem to get that 1250= c^2. then sqaure root both sides. c= sqrt(1250). jailbreak to get c=(5 x 5 x 5 x 5 x 2), and take the fives out from under the square root to get 25 x sqrt2.
