Given:
The system of equations is
...(i)
...(ii)
To find:
The number that must be multiplied with the second equation to eliminate the y-variable.
Solution:
Coefficient of y variable in equation (i) is 3 and in equation (ii) is -1.
To eliminate y-variable the absolute value of coefficients of y-variables should be same.
So, we need to multiply the second equation by 3 to eliminate the y-variable
Multiplying equation (ii) by 3, we get
...(iii)
Adding (i) and (iii), we get
Divide both sides by 7.
Put x=12 in (i).
Divide both sides by 10.
Therefore, x=12 and y=10.
Section A) The AROC for Part A is 4.
h(x) = 4 * 1. 4 is your answer.
Section B) The AROC for Part B is 1.
h(x) = 4 * 1. 4 is your answer.
Part A: (Above)
Part B: There is no greater average change, both X's AROC is 4.
A.R.O.C: (Average Rate of Change)
I think this is right. Not 100% though
Answer:
Nominal
Step-by-step explanation:
There are four levels of measurement of data listed below in increasing order:
Nominal
Ordinal
Interval
Ratio
The nominal level of measurement is the lowest level that deals with names, categories and labels. It is a qualitative expression of data e.g Colors of eyes, yes or no responses to a survey, and favorite breakfast cereal all deal with the nominal level of measurement.
Data at this level can't be ordered in a meaningful way, and it makes no sense to calculate things such as means and standard deviations.
