The nerve which provides sensory innervation to the skin of the lateral 2/3 of the palm of the hand is Median nerve

Explanation:

This nerve contains fibers from C6 to T1. In addition to having sensitive functions,this nerve also fulfills motor functions in the arm.

Answer with Explanation:

Provided that Mandy's Table is this.

[ x ][ 1 ][ 2 ][ 5 ][ 10 ]

-------------------------------

[ y ][ 5 ][ 10 ][ 25 ][ 50 ]

5/1 = 10/2 = 25/5 = 10/50

"Proportional relationship" refers to an equal set of ratios in a statement or a table which shows "equivalent ratios."

As seen in Mandy's table, the last set if ratio is not equivalent to the other set of ratios because Mandy has incorrectly written the ratio. Instead of , she wrote . So, this makes it not equivalent to .

The table is actually proportional, but Mandy made an error in writing the last ratio, that's why it looks not proportional.

So, this explains the answer.
