I don't know what the answer is, but if I were you I would choose C
Answer:
Undercoverage
Step-by-step explanation:
using the telephone directory as the source of survey subject could lead to undercoverage because the sole reason for carrying out a survey is to select a sample that represent the whole populace not a sample that represent those that have telephone.
undercoverage will be a constraint because people without a telephone or people with telephone number not on the telephone directory were not observe in the sample frame and could lead to confounding.
Answer:
eleven more than a number squared, decreased
by six;
evaluate when t = 5
Evaluating Expressions
Write the expression as 11 +t2 -6
Write the expression as 11 +2t -6
Write the expression as t underscore 2
The value when t = 5 is 16.
The value when t = 5 is 30.
The value when t = 5 is 7.5.
F(x) = (x+7)²
(x+7)(x+7) = x(x+7)+7(x+7) = x² + 7x + 7x + 49 = x² + 14x + 49
(x+9)² = (x+9)(x+9) = x(x+9)+9(x+9) = x² + 9x + 9x + 81 = x² + 18x + 81
(x+5)² = (x+5)(x+5) = x(x+5)+5(x+5) = x² + 5x + 5x + 25 = x² + 10x + 25
(x-9)² = (x-9)(x-9) = x(x-9)-9(x-9) = x² - 9x - 9x + 81 = x² - 18x + 81
(x-5)² = (x-5)(x-5) = x(x-5)-5(x-5) = x² - 5x - 5x + 25 = x² - 10x + 25
I think g(x) based on the translation would be g(x) = (x+9)²
