The tree diagram shows the four possible outcomes when a coin is tossed twice. If H and T represent "heads" and "tails," respectively, then the four outcomes are HH, HT, TH, and TT.

a. Make a tree diagram showing the outcomes if a coin is tossed 3 times.

b. The solid lines of the tree diagram are called branches and the elements of the bottom row (H, T, H, and T) are called leaves. How many branches and leaves are in your diagram for part (a)?

c. How many branches and leaves would there be in a tree diagram showing the toss of a coin 10 times?

Describe the implications of the phrase “normally expected to be liquidated with expendable available financial resources” as applied to accruing liabilities for compensated absences in governmental-type funds?

Write the opposite and the absolute value of each number. -3/-5

Volunteers for the local birding group located a roost of robins and starlings. They were able to determine that the ratio of robins to starlings was 7 to 5 in a hemlock tree that had 120 robins and starlings. How many robins were in the tree?

Find (a) the additive inverse (or opposite) and (b) the absolute value of $7-7$.

How does sunlight help build the trunk, branches, and leaves of this tree?

State whether the following sentences are true or false regarding proprietary-type funds and the accounting measurements made within them. If the sentence is false, state why.

1. Enterprise Funds are used when a governmental entity sells products or services primarily to external parties (such as the general public) for a fee or user charge.
2. An Enterprise Fund may not be used if the entity, such as a provider of mass transit services, receives subsidies from the General Fund.
3. To ascertain the amount of capital assets acquired by an Enterprise Fund during the year, you should read the statement of revenue, expenses, and changes in net position.
4. When Enterprise Funds are used, expenses are accrued only if they are expected to be paid within 60 days after the end of the year.
5. When Enterprise Funds are used, revenues are recognized in the period they are earned, even if cash has not been received.

How is relative dating of fossils different from absolute dating?

The speed of the head of a red headed woodpecker reaches $5.5 \mathrm{~m} / \mathrm{s}$ before impact with the tree. If the mass of the head is $0.060 \mathrm{~kg}$ and the average force on the head is $6.0 \mathrm{~N}$, find

Why do most ecologists and foresters view tree plantations as croplands?

For the following question, graph the absolute value function.

$$f(x)=|2 x-4|$$

A biologist has found that the number of branches on a certain rare tree in its first few years of life can be modeled by the polynomial $b(y)=4 y^2+y$. The number of leaves on each branch can be modeled by the polynomial $l(y)=2 y^3+3 y^2+y$, where y is the number of years after the tree reaches a height of 6 feet. Write a polynomial describing the total number of leaves on the tree.
