The money raised and spent (both in millions of U.S. dollars) by all congressional campaigns for 8 recent 2 -year periods are shown in the table. The data can be modeled by the regression equation

$\hat{y}$=0.943 x+21.541.

Money raised, x	471.7	659.3	740.5	790.5	781.3	1047.3	969.5	1206.1
Money spent, y	446.3	680.2	725.2	765.3	740.4	1005.6	936.3	1156.8

Use the data to find the

a) coefficient of determination and interpret the result,

b) standard error of estimate $s_e$ and interpret the result.

Use the key terms to complete the following sentence:

The __________ is the rate banks are charged to borrow money from the Fed.

A wheel with a rotational inertia of $4.5 \mathrm{~kg} \cdot \mathrm{m}^2$ accelerates at a rate of $3.0 \mathrm{rad} / \mathrm{s}^2$. What net torque is needed to produce this acceleration?

The total amount of money in a bank account paying compound interest can be determined by the formula $A=P\left(1+\frac{r}{n}\right)^{n t}$, where $P$ is the principal (amount deposited), $r$ is the annual rate of interest expressed as a decimal, $n$ is the number of times the interest is compounded in one year, and $t$ is the time in years. Determine the total amount of money in an account at the end of 4 months if the original sum deposited was $\$ 2550$, the interest rate is $8 \%$, compounded 4 times a year, and no money is deposited or withdrawn.

The row echelon form of a system of linear equations is given. (a) Write the system of equations corresponding to the given matrix. Use x, y; or x, y, z; or

$$x_1,x_2,x_3,x_4$$

as variables. (b) Determine whether the system is consistent or inconsistent. If it is consistent, give the solution.

$$\left[ \begin{array}{rrrr|r} 1& 3& 0 & 4 & 1 \\ 0& 1& 2 & -1 & 2 \\ 0& 0& 1 & 2 & 3 \\ 0& 0& 0 & 1& 0 \end{array} \right]$$

Toward the end of the twentieth century, the U.S. government wanted to save money by closing a small portion of its domestic military installations. While many people agreed that saving money was a desirable goal, people in areas potentially affected by a closing soon reacted negatively. Congress finally selected a panel whose task was to develop a list of installations to close, with the legislation specifying that Congress could not alter the list. Since the foal was to save money, why was this problem so hard to solve?

Use the procedures developed in this chapter to find the general solution of each differential equation. $y^{\prime \prime \prime}-y^{\prime \prime}=6$

When Ayana arrived home from the fair she wanted to determine how much she and Zachary had left of the money they took to the fair. This expression represents the total amount of money Ayana and Zachary have left of the $60 each that they took to the fair 60 ⋅ 2 − [2 ⋅ 8 + ((8 + 5) + 5) ⋅ 3 + (1 + 2) ⋅ 3 + 5] Evaluate the expression to find how much money they returned home with.
