in price? 29. The following table gives the frequency distribution of thickness of computer chips (in nanometers; one nanometer is one billionth of a meter) manufactured by two companies A and B. Thickness of computer chips 5 10 15 20 25 30 (in nanometer) Company A 10 15 24 20 18 13 No. of chips by Company B 12. 18 20 22 24 4 By calculating coefficient of variation, which company may be considered more consistent? 30. A buyer obtained samples of electric fan from two companies A and B. He got these samples​

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5

step-by-step explanation:

56

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

just needed some points but try socratic
