A man of mass 70.0 kg sits on the end of a seesaw of length 4.00 m, pivoted in the middle. His end of the seesaw is on the ground. A standing woman grasps and exerts a force straight down on the raised end, which is initially $2.00 \mathrm{~m}$ off the ground. What minimum torque must she exert just as the seesaw becomes level?

2b. $\$ 31,875.32 \div 30$

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.

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.

Make up a fractional-part question about money, as in Example 2 part c. Then find the answer.

Calculate the mass of a solid iron sphere that has a diameter of $3.00 \mathrm{~cm}$.

Use the data to find the

(a) coefficient of determination and interpret the result, and

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

The money raised and spent (both in millions of U.S. dollars) by all congressional campaigns for eight recent years are shown in the table. The data can be modeled by the regression equation $\hat{y}$ = 1.020x - 25.854.
