PLZ HELP ME Sally learned that she could make an electromagnet by wrapping wire that has an electrical current running through it around a steel nail. The number of paper clips the electromagnet can pick up can be increased by increasing the number of coils of wire around the nail. Sally hypothesized that for each 8 coils, she would be able to pick up one additional paper clip.

When she ran the experiment, Sally observed and recorded the following data:Which

statement about Sally’s experiment is correct?

A. The experimental data supports Sally’s hypothesis.

B. Every time Sally added 2 coils to the nail, the total number of paper clips lifted increased by 8.

C. Every time Sally added 8 coils to the nail, the total number of paper clips lifted doubled.

D. The experimental data does not support Sally’s hypothesis.

this is science

Step-by-step explanation:

Sally's hypothesis can be shown as:

From the data in the table we can see that:

As we see there is a difference, Sally can pick up one paper clip for each 4 coils.

Correct answer choice is D.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
