Five data entry operators work at the data processing department of the birmingham bank. each day for 30 days, the number of defective records in a sample of 250 records typed by these operators has been noted, as follows: sample no. no. defectives sample no. no. defectives sample no. no. defectives 1 7 11 7 21 17 2 5 12 4 22 12 3 19 13 16 23 7 4 9 14 3 24 6 5 10 15 10 25 14 6 9 16 9 26 11 7 12 17 13 27 14 8 10 18 5 28 6 9 5 19 18 29 11 10 13 20 16 30 2 a) establish 3sigma upper and lower control limits.

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test
