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.
Quality of schools data is also ordinal as it involves a ranking or definite ordering of data - from poor to excellent.
Answer:
m=-29/3 and n=65/3
Step-by-step explanation:
The given system has equations:
3m+3n=36
8m+5n=31
Multiply the top equation by 5 and bottom equation by 3 to get:
15m+15n=180
24m+15n=93
Subtract the top equation from the bottom equation to get:
9m=-87
Divide both sides by 9
We substitute this value into the first equation to get:
Answer:

I use symbolab, it's the best calculator for everything. Hope this helps!
This looks familiar, right? Like slope-intercept.
y=mx+b, where m is the slope.
Let's right it like that.
5y=3x-10 (add 3x to both sides, since we want to isolate the y.)
Now divide by 5, since - again - we want to isolate the y.
y= 3/5x-10/5 >>>> y= 3/5x-2
I think the slope is 3/5.
If the line happens to be parallel, the slope is the same. If perpendicular, it is opposite reciprocal. So if it was perpendicular, the slope would be -5/3.
