Answer:
Step-by-step explanation:
Your first step is to find the total number of animals, no matter what they are.
34 + 27 + 12 + 16 + 22 = 111 animals.
You could add all the numbers other than the 12 hippopotamuses together. If you did, you would get 99.
The answer is 99/111 = 0.892
Sometimes it is just easier to do the following. Find the the probability of getting a hippo and subtract that from 1.
12/111 = 0.108
And subtract this number from 1. One represents all of the possible animals.
1 - 0.108 = 0.892
Later on, when you get problems that are more complicated, the second way is the way to do it. It gives you lest grief.
Need more information about the question
To calculate the rate of change, one must divide the total change by the amount of time that it took, in this case years. One can find the total change by subtracting the two quantities, $15,200 and $8,000. This gives a rate of change of $7,200 per four years. To find the change per year, one must do what I said in the first sentence, divide the total change by the amount of time. Doing this, one gets $1,800 changed per year, assuming there was a constant rate of change.

Step-by-step explanation:
I did the other question too so yee lmk again if this is right or not :)
Answer:the first place seller receives $56
The second place seller receives $28
The third place seller receives $20
Step-by-step explanation:
Let x represent the amount that the first place seller would receive.
Let y represent the amount that the second place seller would receive.
Let z represent the amount that the third place seller would receive.
The second place winner will receive 8 more dollars than the third place winner. This means that
z = y - 8
The first place seller will receive twice as much as the second place seller. It means that
x = 2y
The profit portion they will share is $ 104. It means that
x + y + z = 104 - - - - - - - - - - - 1
Substituting z = y - 8 and x = 2y into equation 1, it becomes
2y + y + y - 8 = 104
4y = 104 +8 = 112
y = 112/4 = 28
x = 2x = 2 × 28
x = 56
z = y - 8 = 28 - 8
z = 20
