describe the center and spread of the number of books read by students in mr. chen’s class using either the mean and standard deviation or the five-number summary. justify your choice using the histogram. round to the nearest tenth if necessary.

answer options:
a. the distribution is symmetric, so use the mean and standard deviation.
mean: 5.2, standard deviation: 2.4

b. the distribution is skewed, so use the five-number summary.
range: 8, median: 4.5, half of the data are between 3 and 7

30005

yes ok                                            

it is x=-4

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

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.
