The answer to 33 is 3. The answer to 37 is 9.
Probability =
(number of ways it can come out the way you want it to)
divided by
(total number of ways it can come out).
Total number of ways it can come out =
number of bottles in the cooler
= (10 + 15 + 13) = 38 .
Number of ways it can come out the way you want it to =
(soda + lemonade)
= (10 + 15) = 25 .
Probability of coming out the way you want it to =
25 / 38 = about 65.8 % .
Answer:
(-3, 3)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
-5x - y = 12
y = -4x - 9
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -5x - (-4x - 9) = 12
- Distribute negative: -5x + 4x + 9 = 12
- Combine like terms: -x + 9 = 12
- Subtract 9 on both sides: -x = 3
- Divide -1 on both sides: x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = -4x - 9
- Substitute in <em>x</em>: y = -4(-3) - 9
- Multiply: y = 12 - 9
- Subtract: y = 3

Answer:
I might be wrong for this. But in my opinion, the answer might be C. Please correct me if I am wrong.
Step-by-step explanation:
If you look at the graph, the one dot is on 4 which is on the x axis of the positive side. the other dot is connected to the y axis which is also the positive side and it lands directly on 3. I honestly have no further explanations, but hopefully, someone can correct me for this mistake.
