Answer:
1. YES, The probability of of picking one with today's date is less than 1 because there is a chance of picking something else, you cannot say it is certain to pick today's date randomly.
2. YES, the probability of picking one with a different date is greater than 0 because there is a chance you could pick one of these. You cannot say it will never happen that you choose one with a different date.
3. .15 is the probability of picking today's date. (3 / 20)
4. .85 is the probability of picking a different date. (17 / 20)

Step-by-step explanation:
<u>Step 1: Define Equation</u>
2(x + 4) = 4x + 3 - 2x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 2x + 8 = 4x + 3 - 2x + 5
- Combine like terms: 2x + 8 = 2x + 8
- Subtract 8 on both sides: 2x = 2x
- Divide 2 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>.
∴ x = infinite amount of solutions
Answer:
21a + 17b
Step-by-step explanation:
To simplify, we need to distribute the 9 to the terms inside of the parentheses that it is being multiplied by and 4 to the terms inside of the parentheses that it is being multiplied by like so:
9(a)+9(b)+4(3a)+4(2b)
9a+9b+12a+8b
Add like terms
21a + 17b
