evablogger [386]

Answer:

Step-by-step explanation:

Given that confidence level is 95% and sample mean is within 10 minutes of the population mean.  i.e. margin of error = 10

Std deviation of population= 211 minutes

Margin of error = Z critical * std error

Std error = sigma/sq rt n = \frac{211}{\sqrt{n} }

Hence we have

\frac{211}{\sqrt{n} }\frac{211}{\sqrt{n} }*1.9641.356\\n>1710

The minimum sample size is 1710

a) There may not be 1,809 computer users to survey

Question 4 (1 point) Determine whether the ordered pair (3,28) is a solution to the equation 2x- y/2 = -8 (3, 28) Is a solution
bulgar [2K]

Answer:

It is a solution

Step-by-step explanation:

Given

2x - \frac{y}{2} = -8

Required

Determine if (3,28) is a solution

(3,28) implies that:

x = 3

y = 28

To check if it is a solution, we simply substitute values for x and y in the given equation;

2x - \frac{y}{2} = -8

2(3) - \frac{28}{2} = -8

6 - 14= -8

-8= -8

Since both sides of the equation are equal; then, Yes, it is a solution
