Ms. Romano, a city council member, decides to develop a survey. (a) Give an example of a question she could ask on her survey. (b) How could she select a simple random sample of drivers to take her survey? (c) She gives out 220 surveys but receives only 55 completed surveys. What are the sample and population for Ms. Romano's research? (d) Of the 55 drivers who completed surveys, 11 said that they text while driving. If Ms. Romano uses only the completed surveys, what conclusion could she make about the percent of drivers in her city who text while driving?

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
