Total no. of births = 2000
Births of girls = 64
Birth% of girls




Hence, the number of girls are significantly low.
Answer:
-10/3 is the answer
Step-by-step explanation:
Given are two complex numbers as

Recall Demoivre theorem as
(cosA+isinA)(cos A+isin B) = cos(A+B)+isin(A+B)
Hence here we have sum of angles as
A+B = 63+117 =180

=
Since sin180=0 and cos 180=-1
1) cluster
2) outlier
3) association
4) trend line
5) scatter plot
