Answer:
1.) -2 - 1i
2.) -2 - 1i
3.) commutative
Explanation:
Given :
z = 1 + 3i
w = −3 − 4i
1.)
z + w :
1 + 3i + (-3 - 4i)
1 + 3i - 3 - 4i
1 - 3 + 3i - 4i
-2 - 1i
2.)
w + z
-3 - 4i + 1 + 3i
-3 + 1 - 4i + 3i
-2 - 1i
z + w = w + z
Hence, come number addition are commutative

Its authority is from the US Constitution which says "Congress shall have power to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries."
Answer/Explanation:
Statistical significance would mean that the researcher carried out the appropriate statistical tests to confirm that the difference between the two age groups was unlikely to be a result of chance.
Likely, a researcher would want the p value (probability value) to be less than 0.05, which means there is only a 5% chance that these observations are random.
The test a researcher would likely perform to test statistical significance on this data is an unpaired t test, which compares the averages of two independent groups to see whether there is a significant difference between them.
Answer:
