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:
Interval level of measurement
Step-by-step explanation:
There are four level of measurements; nominal, ordinal, interval and ratio.
Nominal level of measurements separates data into exclusive categories. There is no ranking or order required in the data. Temperature is not divided into categories.
Ordinal level of measurements separates data into exclusive categories like nominal but there is ranking and order required for the data. Temperature doe not require categories or ranking.
Interval level of measurement ranks data where there are differences between units of measure but there is no meaningful zero. For temperature, a zero is not required and the interval between values is interpret-able. For example, the distance between 67 to 67 is the same as distance between 67 to 71, 71 to 75 and 75 to 79 degree f.

<h3>Answer is -9</h3>
=================================
Work Shown:
(g°h)(x) is the same as g(h(x))
So, (g°h)(0) = g(h(0))
Effectively h(x) is the input to g(x). Let's first find h(0)
h(x) = x^2+3
h(0) = 0^2+3
h(0) = 3
So g(h(x)) becomes g(h(0)) after we replace x with 0, then it updates to g(3) when we replace h(0) with 3.
Now let's find g(3)
g(x) = -3x
g(3) = -3*3
g(3) = -9
-------
alternatively, you can plug h(x) algebraically into the g(x) function
g(x) = -3x
g( h(x) ) = -3*( h(x) ) ... replace all x terms with h(x)
g( h(x) ) = -3*(x^2 + 3) ... replace h(x) on right side with x^2+3
g( h(x) ) = -3x^2 - 9
Next we can plug in x = 0
g( h(0) ) = -3(0)^2 - 9
g( h(0) ) = -9
we get the same result.
