mr. teslers typing class conducts weekly typing drills. the list beloe shows the number of words per minute students in his cladd ty0ed last week. 42, 55, 62, 39, 70, 54, 56, 73, 55, 63, 58, 47, 38, 72, 48. which of the following scenarios would change the range from 35 to 38?​

Answer is in the photo. I can't attach it here, but I uploaded it to a file hosting. link below! Good Luck!

the 4th choice is the correct one

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
