None of these best represents the sea level because the sea level is 0, which is neither negative nor positive and the whale is at 3000 below sea level and the Griffon is at 37,000 above sea level.
For 4, the answer should be 3:1
To find that answer take 1.5 and divide it by 0.5
And for 5, the answer would be 3/4
For this case we have the following mixed numbers:

We convert each mixed number into decimal:
Mercury orbits:
Venus orbits: 
Mars orbits: 
Answer:
Mercury orbits: 87.96
Venus orbits: 224.7
Mars orbits: 686.98
Answer:
Your Winnings are $ -1
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
Since we are not told what two balls were actually drawn, then the expected winnings would be of the greatest probability occurring. To figure this out we need to calculate the probability of getting two red balls consecutively and the probability of getting two different colors consecutively. Since there are a total of 10 balls the probabilities of getting one ball would be the following,
Red: 
Green: 
Now we need to know the probability of us getting 2 reds together, two greens, or one of each.
2 Reds: 
2 Greens: 
1 Each: 
So we can see that the highest probability is getting 2 Greens in a row. Meaning you would have to pay $1
