36 Using his ruler, Howell measured the sides of a
rectangular prism to be 5 cm by 8 cm by 4 cm. The

actual measurements are 5.3 cm by 8.2 cm by 4.1 cm. Find
Howell’s relative error in calculating the

volume of the prism, to the nearest thousandth.

**PART IV**

37 A password consists of three digits, 0 through 9, followed
by three letters from an alphabet having

26 letters.

If repetition of digits is allowed, but repetition of letters is
not allowed, determine the number of

different passwords that can be made.

If repetition is not allowed for digits or letters, determine
how many fewer different passwords can

be made.

38 Graph the solution set for the inequality 4x - 3y > 9 on
