Amy and her family were traveling during their vacation. At point 1, her watch said 11:15. It took her 80 miles to get to Point 2 at 1:15. Based on this information, what is the unit rate (in miles per hour) of the car? Based on the unit rate, how many miles would the family drive in 45 minutes? Amy’s dad said that the entire trip was 1200 miles. How many hours will it take to complete the trip?

What are different types of statistical programs

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a, b and c integers and a> 1

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.
