A plumber has a 36-in pipe he must cut it into two pieces so that one piece is 14 inches longer than the other how long is each

ioda

The longest piece is 25 inches and the shortest piece is 11 inches.

(36/2) - (14/2) = shortest piece
18 - 7 = 11 (shortest piece)

36 - 11 = 25 (longest piece)

25 - 11 = 14 inches difference between the pieces

Answer:

Mean: 49

Mode: none, since all the numbers only appear once

Median: 48

Range: 69

Step-by-step explanation:

53+64+19+25+88+48+46 = 343

343/7= 49 (mean)

19, 25, 26, 48, 53, 64, 88 (middle number is 48, so the median is 48)

Range= largest number-smallest number

88-19= 69 (range)
