1. In Excel 2010 cell Al contains the formula =MID("12345678", 4, 2). What is displayed in cell A1? a) 56 b) 55 c) 34 d) 45 x e) None of the above

34. (2 points) Add the missing method, blackSquare(), to the program below so it produces the image shown. The squares are filled with black and have a black outline. (Hint: Using rectMode(CENTER) makes it easier.) void setup() { int sz = 5; for (int y = 5; y < height; y = y + sz*2) { blackSquare (width-y, y, s2); fill (255); // white ellipse (width - y, y+sz, sz, sz); SZ = S2 + 2;
