Using it's concept, it is found that the sample proportion for this population is of 0.4.

  • The estimate of the <em>sample proportion for a population</em> is given by the <u>number of desired outcomes divided by the size of the sample</u>.

In this problem:

  • 1,599 of those surveyed responded in favor of the park.
  • The sample size is of 4,000.

Hence:

p = \frac{1599}{4000} = 0.4

The solution of f(x)=x^3-2x^2- 9x + 18 is
Tom [10]

Answer:

x = -3, 2, 3.

Step-by-step explanation:

f(x )= x^3 - 2x^2 - 9x + 18      We factor this by grouping:

f(x) = x^2(x - 2) - 9(x - 2)

f(x) = (x ^2- 9)(x - 2)

f(x) = (x - 3)(x + 3)(x - 2).

The zeroes of the function are:

x = -3, 2, 3.
