Explanation:
I'm assuming letters can repeat.
There are 26 letters in the English alphabet.
There are,
- A = 26^4 = 456,976 strings of length four
- B = 26^3 = 17,576 strings of length three
- C = 26^2 = 676 strings of length two
- D = 26 strings of length one
Overall, there are A+B+C+D = 456,976+17,576+676+26 = 475,254 strings of length four or less.
D. Use the formula V=πr^2 h.
Recall that, an absolute value expression is a piece-wise in effect, thus we'd check the single-sided limits,
Step-by-step explanation:
Given that the set of data collected has an extreme value (24), a Median measure of center is more appropriate than a Mean measure.
We sort the same data collected in increasing order:
{0, 1, 2, 4, 4, 5, 5, 24}
There are 8 elements inside the set, so we check the 4th and 5th elements (closest to the center), which are 4 and 4.
Since they are equal, the Median is 4.
Our answer is Median; 4.
