Researchers asked 250 families whether or not they were homeowners and how many cars they had. Their responses are summarized in the following table.

Total of non home owners is 45 + 85 = 130

Percentage would be 130/250 = 0.52

0.52 x 100 = 52%

Number who have no car or one car = 20 + 45 = 65

Percentage = 65/250. = 0.26 = 26%

hope this helps

Step-by-step explanation:

what are the statments

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.
