matched

Step-by-step explanation:

Variable                              scale of measurement

-Gender                                      nominal scales

-Martial status                             nominal scales

-credit rating                                ordinal scales

( low, medium, high)

-Annual income                            Quantitative

-Age                                               ratio scale

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
