Flip two different coins 100 times, and record the results of each coin toss in a table like the one below:
Result
Frequency
Two heads
34
Two tails
47
One head, one tail
22
Answer the following questions based on the data you gathered. You must show your work to receive credit.
What is the theoretical probability that a coin toss results in two heads showing?
1 4 = 25%
What is the experimental probability that a coin toss results in two heads showing?
34/100 = 34%
What is the theoretical probability that a coin toss results in two tails showing?
2/4 = 50%
What is the experimental probability that a coin toss results in two tails showing?
47/100 = 47%
What is the theoretical probability that a coin toss results in one head and one tail showing?
1 4 = 25%
What is the experimental probability that a coin toss results in one head and one tail showing?
22/100 = 22%
Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?
Our hypothesis is our theoretical possibility, and our experimental chance is our experiment.

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
