Answer:
27.5 = CE
Step-by-step explanation:
The two triangles should be similar to each other, so we can set up a ratio of 15:6. This gives us a final ratio of 2.5:1 Multiply EA = 11 by 2.5 to find its corresponding side measure
11*2.5 = 27.5

Answer:
Step-by-step explanation:
For a coin, the probability of head showing in a single toss is 
.
Its complement, the probability of not head is
This is a binomial distribution. In 
tosses, the probability of having all heads (i.e. heads) is
Let's call this value 
.
For 
coins, we determine the probability of at least 1 coin showing all heads by first finding its complement i.e. the probability of no coin showing all heads. This is also a binomial distribution.
