A market researcher for a provider of music player accessories wants to know the proportion of customers who own cars to assess
AVprozaik [17]

Answer:

a) The estimated standard deviation of the sampling distribution of the​ proportion is 0.023

b) the estimated standard deviation have been if he had surveyed only 100 customers is 0.046

Step-by-step explanation:

given information:

the number of sample, n = 400

sample proportion, p = 70% = 0.7

a) standard deviation of a sample proportion is

σ = \sqrt{\frac{p(1-p)}{n}}

  = \sqrt{\frac{0.7 (1-0.7)}{400} }

  = 0.023

b) if n = 100, so

σ = \sqrt{\frac{p(1-p)}{n}}

  = \sqrt{\frac{0.7 (1-0.7)}{100} }

  = 0.046

Drag each graph to show if the system of linear equations it represents will have no solutions, one solution at (2,6), one solut
hjlf

Answer:

see the explanation

Step-by-step explanation:

<u><em>Verify each case</em></u>

Part 1) The graph show two identical lines, then the system has infinitely many solutions

Part 2) The graph show two perpendicular lines.

Remember that the solution of the system is the intersection point both graphs

The intersection point is (2,6)

therefore

The system has one solution at (2,6)

Part 3) The graph show two intersecting lines at (-6,-2)

Remember that the solution of the system is the intersection point both graphs

The intersection point is (-6,-2)

therefore

The system has one solution at (-6,-2)
