• The statement varies jointly as and may be translated into mathematical symbol as = , where is the constant of variation.

• Steps in Solving a Joint Variation Problem
1. Write the equation of variation.
2. Substitute known values and solve for k or constant of variation.
3. Replace k in the equation in step 1 by the value obtained in step 2.
4. Solve for the desired value

The constitution gives congress the power to create federal courts lower than the supreme court higher than the supreme court equal to the supreme court, unaffected by the supreme court.

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem.
