The radius of the circle expressed as a mixed number is: 
inches.
<h3>What is the Radius of a Circle?</h3>
Radius of a circle = half the measure of the diameter of a circle.
Given:
diameter of a circle = 
inches
Therefore:
Radius of the circle = 1/2()
= 1/2(47/6)
= (1 × 47)/(2 × 6)
= 47/12
= inches.
Therefore, the radius of the circle expressed as a mixed number is: inches.

Answer:
We need a sample size of at least 719
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
How large a sample size is required to vary population mean within 0.30 seat of the sample mean with 95% confidence interval?
This is at least n, in which n is found when 
. So

Answer:
This is the associative property.
Step-by-step explanation:
The only operation in this expression is multiplication.
We know that the order in which we multiply numbers does not change their product; therefore we can group different numbers together and get the same product.
In this case, on the right hand side, 3 and 4 are grouped together first, then multiplied by 6. This gives us 12*6 = 72.
On the left hand side, 4 and 6 are grouped together first, then multiplied by 3. This gives us 24*3 = 72.
