Answer: 
Step-by-step explanation:
Since a Binomial is an algebraic expression of the sum or the difference of two terms.
Therefore, For a binomial an expression must contain exactly two terms.
In a)
there is only one term therefore it is not the Binomial.
In a)
, there is only one term therefore it is not the Binomial.
In a)
there is exactly two terms therefore it is a Binomial.
In a)
there are three terms therefore it is not the Binomial.
Morse code is essentially the same as binary. That is, there are two "digits", a dot or a dash.
There are 26 letters in the English alphabet. Clearly, we can't just use one dot or dash, since that could only encode 2 letters at the most. We can't use two symbols because that could only encode 4 letters at the most. Similarly, 3 symbols means

letters at most.
We have to select the smallest power of 2 that exceeds or is equal to 26. In this case,

, so we would have to use up to 5 symbols to encode each letter in the alphabet.
Answer:
Step-by-step explanation:
20,24,25,27,31,35,38
minimum;20
medium: 27
maximum: 38
lower quartile: 24
upper quartile:35
put numbers in number order
the first number is the minimum, the last number is the maximum. the middle number "split" is the median.
quartiles are the numbers in the middle of the data you just "split"
(so like a quarter)
i may be wrong i haven't done this in years
