When interpreting study results, which is true?

What does R2 represent?

This scatterplot shows: 

Under the assumption that m is a positive integer, compute (7m+9) mod 7

Suppose that \(A\subset B\) , so \(A\) is a proper subset of \(B\). What else can you for sure conclude must be true? Select all that apply (Hint: it could help to draw a picture). Note on notation: \(S\not\subseteq T\) means “S is not a subset of T”, i.e. \(\neg (S\subseteq T)\)

What does SIGECAPS stand for? Be sure to write in a response for each letter.

Code Segment 1if (a > 0)   if (b < 0)      x = x + 5;   else      if (a > 5)         x = x + 4;      else         x = x + 3;else   x = x + 2; Refer to Code Segment 1. If x is currently 0, a = 5 and b = 5, what will x become after the statement shown is executed?   

These two ways to set up a String will yield identical results:String my_string = new String(“123.45”);String my_string = “” + 123.45;

Refer to Class Definition Code Segment 3: Which of the following could be used to instantiate a new Student s1?

Write code that outputs all of the int values between 1 and 100 with five values per line, and each of those five values spaced out equally.  Use a single for loop to solve this problem.
