Final answer:
Kimani should click on the Illustrations group after the Insert Tab and the Size group after the Format Tab to insert and adjust images in Excel.
Step-by-step explanation:
The answer to the student's question about the series of clicks and entries Kimani needs to follow to insert and adjust a picture in Excel is as follows:
- X in the series 'Insert Tab > X > Pictures' can be interpreted as 'Illustrations' since that is the group in Excel where the Pictures option is found.
- Y in the series 'Format Tab > Y > Edit height and width' could be 'Size', as this is the group in Excel's Format Tab where you can adjust the height and width of a picture.
Therefore, Kimani would click on Insert Tab > Illustrations > Pictures to insert a picture. After inserting it, she would then go to Format Tab > Size to adjust the picture's height and width to fit the cell.
