Mark recorded the temperature each day for a week. He calculated the mean temperature and found it was 21.6°C
Mark’s thermometer was not working properly. All seven temperatures were 3° too high.
Write down the correct mean temperature.

Step-by-step explanation:

130.2/7= 18.6

Before finding the correct form you need to find their total sum and subtract 21 from it since the number of temperature recordings are 7

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
