Doctors at a research hospital are conducting a study to see if flu patients received a flu vaccination in the past year. To
collect their data, they ask each person treated for the flu at their hospital whether they received the vaccination,
Identify the correct experiment, trial, and outcome below:
Select all that apply:
The experiment is recording the number of patients who say that they have received the flu vaccine.
The experiment is asking whether a flu patient received the vaccine.
O
Atrial is asking one patient if they have been vaccinated,
The trial is identifying recording the number of patients who say that they have received the flu vaccine.
An outcome is no, the person was not vaccinated.
O
An outcome is asking one specific person whether they have received the flu vaccination

answer:

what is your question that you ask

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

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.
