Answer:
$24
Step-by-step explanation:
What you do is you just times 84 x 2/7 to get your answer.
84 x 2/7=$24 is your answer.
With n tosses, there are a total of 2^n possible outcomes. We need 15 of theses to be heads.
Since the tosses are random, we want to count the ways to have exactly 15 of them being heads. That will be C(n,15) ways to pick which tosses are heads.
The probability will be given by:
C(n,15)/2^n=0.0148
At this point we use various values of n until we get the correct probability.
n=18⇒0.003112793
n=19⇒0.007392883
n=20⇒0.014785767
n=21⇒0.025875092
Answer:
n=20
Answer:
<u>360 in²</u>
Step-by-step explanation:
Surface Area of the box = 2(lb+bh+hl)
= 2(12×6 + 6×6 + 6×12)
= 2(72 + 36 + 72)
= 2(180)
= <u>360 in²</u>

Therefore D is the right answer.
