Answer:
B. Mean absolute deviation
Step-by-step explanation:
The mean absolute deviation of a dataset is the average distance between each data point and the mean.
Okay. In my opinion, all the class has to do is simplify the expressions and compare. But they want to substitute instead.
Well then.
First, let's notice that these are linear expressions, meaning that if they are equivalent then all their values match up.
Number 1 is not a good one. Just because they're both positive doesn't mean anything; they have to be <em>the same.</em>
This also eliminates 3.
Number 2 is a good one, but it's not as reliable. If, for instance, the two expressions are <em>not </em>equivalent and you get lucky enough to pick that one value they intersect at (or have in common), then you'd be wrong when you say they are equivalent.
Number 4 makes the most sense because if both expressions are equivalent, then every value matches up. If not, then only one will. So having two values to substitute will most definitely answer the class question.
Hope this helps, let me know if I messed up! ;)
Answer:A
Step-by-step explanation:
Interior angles of a triangle ALWAYS have to be equal to 180
The sum of A is 180, however, those angles wont work because they have to be more close to eachother for it to be possible
The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides
Answer:
y = 1/2 x + 8
Step-by-step explanation:
We are given the y intercept and the slope, so we can write the equation using the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 1/2 x + 8
