Answer:
a. an = -1 • 4^(n - 1)
Step-by-step explanation:
It's easy see that each term is multiplied by 4 to get the next term, so the common ratio will be 4, that reduces the choices to answers A and B (since C and D use -1 as common ratio). Also, normally a geometric progression uses "n-1", so we'll first try with A to see if it works.
a1 = (-1) * 4^0 = -1 * 1 = -1
a2 = (-1) * 4^1 = -1 * 4 = -4
a3 = (-1) * 4^2 = -1 * 16 = -16
Yes, it works... so the answer is an = -1 • 4^(n - 1)

Answer: Ordinal
Step-by-step explanation:
We know that the ordinal scale is a level of measurement which is used when we are ordering attributes according to their ranks or preferences.
For example : In an exam we arrange position of students as :
First > Second > Third and so on.
Given : A group of women tried five brands of fingernail polish and ranked them according to preference. It means she is arranging the brands in an order .
Thus this is an ordinal level of measurement .
Answer:
1. Multiply the slope by 2 and look at the numerator
2. 5/7
3. slide A
4. The run of slide a is shorter which means that its steeper because the rise is the same
5. 10
6. 5 units?
