When designing a study to determine this population proportion, what is the minimum number of drivers you would need to survey t

Vlada [557]

Answer: 601

Step-by-step explanation:

The formula to find the minimum sample size(n) , if the prior population proportion is unknown:

$n=0.25(\dfrac{z^c}{E})^2$ , where E = margin of error , $z^c$ = critical z-value for confidence level c.

Given : E = 0.04

Z-value for 95% confidence = 1.96

So, the minimum sample size required = $0.25(\dfrac{1.96}{0.04})^2=0.25(49)^2$

$= 0.25\times 2401=600.25\approx601$

Hence, the minimum sample size required = 601

What is 1102 using the polynomial identity (a+b)2=a2+2ab+b2 ?

Virty [35]

Answer:

"Let the smaller value a = 10 and the larger value b = 100. Than a^2 + 2ab + b^2 is 10^2 + 2 * 10 * 100 + 100^2. This can be simplified to 12100. So, 110^2 is equal to 12100."

Hope this helped!

A changes saved Set up a proportion and use it to solve for x. 2 10 х 3

V125BC [204]

Answer:

C. 15

Step-by-step explanation:

The following proportional can be set-up for the figure given:

$\frac{x + 3}{x} = \frac{10 + 2}{10}$

Solve for x

$\frac{x + 3}{x} = \frac{12}{10}$

$\frac{x + 3}{x} = \frac{6}{5}$

Cross multiply

$5(x + 3) = x(6)$

$5x + 15 = 6x$

15 = 6x - 5x

15 = x

x = 15
