Elizabeth is going to flip a fair coin 100100100 times. what is the best prediction for the number of times that the coin will land tails up

50050050

Step-by-step explanation:

It should be about 50%, so 100100100 divided by 2 = 50050050

50050050

Step-by-step explanation:

There is a 50% chance for the coin to either land on heads or tales so you divide 100100100 by 2 to get 50050050 this would work with anything else say you need to figure out the chance of a coin landing on heads and the coin flips 550 times to figure out the chance you do 550 divided by 2 and you get 225. But anyways the answer is 50050050. the reason you divide by two is because the coin has 2 sides, if it were a dice, for instance, you would divide by 6 because it has 6 sides

47 - 90 = 43

43 - 180 = x

x = 137

i believe that the answer is

b. y-1=-2(x-4)

hope this !
