5,126 ÷ 9 = 569.555555555556 totally answer
Answer:
√(2 - 7x) + 2x = 0
√(2 - 7x) = - 2x
[√(2 - 7x)]² = (- 2x)²
2 - 7x = 4x²
4x² + 7x - 2 = 0
4x² + 8x - x - 2 = 0
4x(x + 2) - (x + 2) = 0
(4x - 1)(x + 2) = 0
4x - 1 = 0 => 4x = 1 => x₁ = 1/4
x + 2 = 0 => x₂ = - 2

<em>100 people of all ages.</em> If they pick any number of people at the city park, that's considered a bias, because what if the typical city park goers are in their 20s-30s? what if they're made up of ONLY dog owners? these are irrelevant details that shadow away from the true, useful, unbiased results.
Secondly, if they choose a smaller amount of people, they'll get a smaller number of responses, which could lead their study astray.
