Answer:
<em>Decimal Form; 0.216 </em>
Step-by-step explanation:
If we are to convert to a decimal, move the decimal point 2 to the left, as such;
21.6 percent ( % ), ⇒ move decimal place two to the left,
<em>Decimal Form; 0.216 </em>

Answer:
<h2>132.25π m²</h2>
Step-by-step explanation:
The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.
then
by equating the last two expressions we get: 23π = 2πr then r = 23/2
then
the area = π × r² = (23/2)²×π = (132.25)×π
Answer:
1.691
Step-by-step explanation:
Standard error of the mean is expressed as SEM = S/√n
S is the population standard deviation
n is the sample size (number of observation)
Given S = 27 and n = 255
SEM = 27/√255
SEM = 27/15.97
SEM = 1.691
Hence the standard error of the mean is 1.691
