What is the z-score for Paula If she got 1400 on the SAT, the mean was 1100 and the standard deviation was 275?

Yea it is 275 with standard subtract
1400-deviation=275

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
