Help me please

I believe the independent would be the BIC pen and dependant would be the Papermate blue

The controlled variable would be the two pens because there is no way to change which one lasts longer except maybe adding more ink.

I hope this helps, not sure if it will.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

where are the images of the functions i can only see the question you typed.
