Answer:
Step-by-step explanation:
Given that you and a friend play a game where you each toss a balanced coin.
If the upper faces on the coins are both tails, you win $1;
if the faces are both heads, you win $2;
if the coins do not match (one shows a head, the other a tail), you lose $1 (win (−$1)).
Let Y be the amount won
Then Y can take values as 1,2 and -1
The above is the probability distribution for Y.
Attached is the solution, long division is hard to type out.

Answer:
9: D 10: A
Step-by-step explanation:
So basically 5x+5/(x)(x)-2. the integers involving vertical movement I think would be 5 and -2
1) the 3 measures of central tendency is mean, median, and mode.
So when finding the average clutch size is by using mean.
Clutch sizes:
114, 103, 121, 118, 107, 103, 104
114+103+121+118+107+103+104
=770
= 770 ÷ 7 ( 7 ⇒ there are seven numbers in total)
= 110
∴ Therefore the average clutch size is 110.
2) Through that table of data, yes, I think that the clutch size influences the survival rates of the offspring because it seems that when the clutch size is big, it is more likely for offspring to survive and return. Yet when the clutch size are small, for example, site E and G, the amount of turtles who returned are 40 and 38. But in site A, C, and D, there are 45 turtles in site A that returned, 55 turtles in site C, and 53 turtles in site D.
3) Possibly is because their clutch sizes are the smallest which made them unnoticeable to predators and more likely to survive and returned.
