Answer:
Ordinal Variables
Step-by-step explanation:
Ordinal level of variable measurement is the level of measurement that depicts high level of ordered relationship among the variable’s observations.
The ordinal level of measurement indicates an ordering of the measurements.
This type of variable have a meaningful order to them. An example is class grade (with possible values of Excellent, Very Good, Good, Credit, Fair and Poor).
Another example is the education level (with possible values of high school, undergraduate degree, and graduate degree).

Answer: No, he is not correct
The number of combinations is 190
============================================================
Work Shown:
We have 10 shirts, 6 hats, and 4 scarves. This is 10+6+4 = 20 items total.
If we randomly pick out an item, then we have 20 to choose from. After selecting that first item, we have 20-1 = 19 items left to choose from.
So there are 20*19 = 380 different permutations. Order matters with permutations.
Since we aren't worried about order, this means that we've double counted so we have to divide by 2 to fix it.
So there are 380/2 = 190 combinations.
You can use the nCr combination formula with n = 20 and r = 2 to get the same result.
Answer:
835
Step-by-step explanation:
We know that the hundreds is 8 and the ones is 5 so the sum needed is 16-(8+5), which equals 3 :)
