Define: voluntary responsea) every possible sample of a given size has the same chance to be selected. b) using extraneous factors to create similar groups. c) the explanatory variable(s) in an experiment. d) successively smaller groups are selected within the population in stages. e) people who choose themselves for a sample by responding to a general appeal. f) choosing the individuals easiest to reach. g) population is divided into similar groups and a srs is chosen from each group. h) gives each member of the population a known chance to be selected. i) directly holding extraneous factors constant.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
