Jorge will flip two quarters at the same time. Complete the tree diagram, and then list the sample
space of this compound event. Use H for heads and I
for tails.

It’s a 50/50 percent chance for both of them

Your Answer wil be I also will explain it :)

0.0003 = 3 x 1 / 10,000 = 3 x 10-4. There is a simple procedure for getting a decimal number into the "standard form" for scientific notation: First, write down the number as the number itself times 100. This can be done because 100 equals one, and any number times one equals that number.

Use Scientific Notation (and only the scientific notation!) to find the answer to the following multiplictions, divisions, additions. 1. 4.1357 x 10-15 * 5.4 x 102 = 2.2 x 10-12 2. 1.695 x 104 ÷ 1.395 x1015 = 1.215 x 10-11 3. 4.367 x 105 * 1.96 x 1011 = 8.56 x 1016 4. 6.97 x 103 * 2.34 x 10-6 + 3.2 x 10-2 = 4.83 x 10-2 5.
