The file sales data.xlsx contains monthly sales amounts for 40 sales regions. write a sub that uses a for loop to color the interior of every other row (rows 3, 5, etc.) gray. color only the data area, columns a to m. (check the file colors in excel.xlsm to find a nice color of gray.)

So im doing this school challenge and the teachers said whats the average text a student gets a day so i need to get about 20 in a day but dont know how can you guys 2163371293

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.
