4 0

Answer:

0.03

Step-by-step explanation:w

standard deviation = ( p(1-p) / n)1/2

p= sample proportion= 55%

n= sample size = 900

standard deviation = ( [55/100] [ 1- 55/100]) / 900)1/2

= (0.55*0.45 / 900)1/2

= 0.0165

margin of error = critical value*standard deviation

[ from graph critical value = 2]

margin of error = 2*0.0165=0.033

The circumference of a circle is 12 inches. What is the radius
IceJOKER [234]
Greetings!

"<span>The circumference of a circle is 12 inches. What is the radius?"...

We can use the formula to find the circumference of circle to solve this:
</span>2 \pi r
<span>
Input the information we know:
</span>2 \pi r=12
<span>
Solve for r, using the properties of equality:

Simplify.
</span>6.28r=12
<span>Divide both sides by 6.28
</span>(6.28r)/6.28=(12)/6.28<span>
Simplify.
</span>r=1.91

The radius is 1.91cm long.

Hope this helps.
