A consultant wants to ask workers at a factory about the workers job satisfaction. Which of the following best describe a system
alexandr1967 [171]

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Define systemmatic sampling

Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size

STEP 2: Determine the answer

The option that follows the systematic sample of workers is the last option because it follows a fixed, periodic interval of "every 4th worker until 80 workers are selected".

Hence, the answer is:

The consultant takes a list of the workers and selects every 4th worker until 80 workers are selected.

Modulus: If z1=-2+3i and z2=1+2i calculate, |z1|, |z2|, and |z1+2z2|
marin [14]
|z_1|=\sqrt{(-2)^2+3^2}=\sqrt{4+9}=\sqrt{13}\\
|z_2|=\sqrt{1^2+2^2}=\sqrt{1+4}=\sqrt{5}\\\\
z_1+2z_2=-2+3i+2(1+2i)=-2+3i+2+4i=7i\\
|z_1+2z_2|=\sqrt{0^2+7^2}=7

Which craftworld should I choose to colect for Warhammer 9th edition:
g100num [7]

Answer:

Ulthwé was caught in the pull of the Eye of Terror, where the Immaterium intersects with realspace. It is a breeding ground for Chaos and a gateway into the Warp. Due to this baleful proximity to the Eye, Ulthwé must be on constant high alert in case of attacks by the Forces of Chaos. Constant risk and warfare has hardened this Craftworld's citizens to hardship. Due to the lack of Aspect Warriors on the Craftworld, Ulthwé maintains a standing militia known as the Black Guardians, who are more skilled and better-trained than the Guardians of other Craftworlds.Step-by-step explanation:

Juli2301 [7.4K]

Answer:

\large\boxed{x=\pm\sqrt{13}}

Step-by-step explanation:

10x^2-6=144\qquad\text{add 6 to both sides}\\\\10x^2=130\qquad\text{divide both sides by 10}\\\\x^2=13\to x=\pm\sqrt{13}
