Drag each place value name to the correct location in Part A. Drag each digit to the correct location on the number in Part B. Each digit can be used more than once, but not all place value names or digits will be used. Maria rounded all of these numbers to the same place value and found the same rounded value for each. The place value she rounded to was the farthest possible place to the right that would give her the same rounded value for each number. In Part A, identify the place value that Maria rounded all of the numbers to. Drag the name of the place value to the box. In Part B, drag digits to show the rounded value of the numbers. Put one digit in each place, and do not leave any places blank.

When solving a logarithm equation, how do you find the missing variable ?

Suppose we have a set of small wooden blocks showing the 26 letters of the english alphabet, one letter per block. (think of scrabble tiles.) our set includes 10 copies of each letter. we place them into a bag and draw out one block at a time. (a) if we line up the letters on a rack as we draw them, how different ways coukl we fill a rack of 5 letters? (b) now suppose we just toss our chosen blocks into a pile, and whenever we draw a letter we already have, we put it back in the bag and draw again. how many different piles of 5 blocks could result? possible? piles will contain at least one repeated letter? (c) if we draw out 5 blocks wit hout looking at them, how many different piles are (d) if we draw out 5 blocks without looking at them, how many of the possible 2. (4) consider the following formula. 12 give two different proofs, one using the factorial formulas and the other combina torial.
