What is the equation x^2+12x-3=16 written in the form (x-p)^2=q using the method of completing the square ?
Alexus [3.1K]

Step-by-step explanation:

{x}^{2}  + 12x -  3 = 16

{x}^{2}  + 12x = 19

{x}^{2}  + 12x + 36 = 19 + 36

(x + 6) {}^{2}  = 55

Please please help!
Dimas [21]

Answer:

C

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, 9) and (x₂, y₂ ) = (3, 1)

d = \sqrt{(3+3)^2+(1-9)^2}

  = \sqrt{6^2+(-8)^2}

  = \sqrt{36+64}

  \sqrt{100} = 10 → C

As a rule of thumb, the sampling distribution of the sample proportion can be approximated by a normal probability distribution
Gennadij [26K]

As a rule of thumb, the sampling distribution of the sample proportion can be approximated by a normal probability distribution whenever the sample size is large.

<h3>What is the Central limit theorem?</h3>
  • The Central limit theorem says that the normal probability distribution is used to approximate the sampling distribution of the sample proportions and sample means whenever the sample size is large.
  • Approximation of the distribution occurs when the sample size is greater than or equal to 30 and n(1 - p) ≥ 5.

Thus, as a rule of thumb, the sampling distribution of the sample proportions can be approximated by a normal probability distribution when the sample size is large and each element is selected independently from the same population.
