Answer:
$34.27
Step-by-step explanation:
First, we should make everything the same value, so convert the 7.1 miles into meters. (11,423.9 meters). Since we are trying to find a value <em>per</em> 500 meters, divide the 11,423.9 meters by 500 to get 22.8478. Multiply this number by $1.50 to get the value 34.2717 and since we are rounding to the cent, that would be $34.27
The probability of getting blue and white counter is 0.2275
Probability is the likelihood or chance that an event will occur
Probability = n(E)/n(S)
- n(E) is the number of events
- n(S) is the sample space
If the the probability of getting a red counter red red 0.35, the probability of getting a blue will be 0.65
Pr(getting blue and white counter) = 0.35 * 0.65
Pr(getting blue and white counter) = 0.2275
Hence the probability of getting blue and white counter is 0.2275

Baseball cards
We know two things:
Gaetano had 52 cards on 3 years
Gaetano had 108 cards on 7 years
Then, from the fourth year to the seventh year he added
108 - 52 = 56 cards
In four years he added 56 cards. Then each year he added
56/4 = 14 cards
Since
14 * 3 = 42
On the first three years he added 42 cards to his collection.
Then he started with
52 - 42 = 10 cards
Answer: Gaetano started his collection with 10 cards and he adds 14 new cards to it each year
