balandron [24]

Answer:

$1.\ \ np\geq 10\\\\2.\ \ n\geq 10x$

Step-by-step explanation:

-Let x be the sample size and n the population size

-The conditions for a one-sample proportion z-test are:

-The sample is randomly selected from the population.

-The sample size is greater than or equal to ten times the population size:

$n\geq 10x\\\\n=2000\\x=150\\10x=1500\\\therefore n\geq 10x$

-The expectation np is greater than or equal to 10:

$np\geq 10\\n=2000, p=0.6\\np=1200\\\\Hence, np\geq 10$

Approximate the real number solution(s) to the polynomial function f(x) = x3 + 2x2 − 5x − 6.

nadya68 [22]

F(1) = (1)^3 + 2(1)^2 - 5(1) - 6 = 1 + 2 - 5 - 6 = -8; x = 1 is not a solution to the polynomial.
f(-1) = (-1)^3 + 2(-1)^2 - 5(-1) - 6 = -1 + 2 + 5 - 6 = 0; x = -1 is a solution to polynomial.
From the options, a or c has x = -1, both has x = , so lets check for x = 3
f(3) = (3)^3 + 2(3)^2 - 5(3) - 6 = 27 + 18 - 15 - 6 = 24; x = 3 is not a solution to the polynomial.
Therefore the solutions to the polynomial are x = -3, x = -1, x = 2

What you have to do is first subtract 20 from 80 and get 60 then use the data to fill in the blanks!
