2. Suppose a coin is flipped 10,000 times. What is a reasonable prediction for the number of times the coin lands on tails?

Set up a proportion and solve. Your response will be a number. No label.

Answer 1

1) 40

2) 5000

Explanation:

QUESTION 1

8:36 = x:180

180/36 = 5

8(5) = x

40 = x

therefore they will screen 40 bags in a group of 180

QUESTION 2

A coin has 2 sides, heads and tails.

So it has a 50% chance of getting heads or tails

50% of 10 000 is 5000

it could land on tails 5000 times and heads 5000 times

hope this helped

Answer 2

Explanation:

1)8/36 x 180= 40 bags

2) im guessing its 0.5 x 10,000=5000
