Answer:
x = 3
Step-by-step explanation:
The equation is,
16 = 5x+1
Subtract 1 from both sides,
16-1 = 5x
15 = 5x
Divide by 5,
x = 3
-3x to the second power - 2
I believe this is your answer.
Answer and Explanation:
Gender data is categorical as it can be sorted into two categories - males and females - and does not involve any numerical values.
Age data is ratio as each person's age is a numerical value and it has a natural zero as point of origin. Moreover, the numerical values cannot be negative.
Ethnicity data is categorical as the various ethnicities to which those surveyed can belong are separate categories. There are no numerical values involved.
Length of residency data is ratio as the length duration is measured in number of years, thus having a numerical value. There is also a natural zero as point of origin and no possible negative values.
Overall satisfaction with city services data is ordinal as it is based on a ranking from poor to excellent.

Answer:
C=2
Step-by-step explanation:
-8(17-12)= -8(5)= -40
then
-2(8-(-2))= -2(10) = -20
so then
-40/-20
=-2
1.28 = 128 * 10^-2
128 * (1/10^2)
128 / 10^2
128 / 100
1.28
Because, it's literally the same thing mathematically if you worked it out. Though, as I'm sure you're aware, it's just a much shorter and cleaner way of writing out large or small numbers.
