Answer:
<h2>6.63</h2>
Step-by-step explanation:
Standard error of the mean is expressed as shown below.
SE = S/√n where;
S is the standard deviation
n is the sample suze
Given parameters
Standard deviation = $23.90
sample size = 13
Required
Standard error of the mean for this distribution.
Substituting the given value into the formula we have;
SE = 23.90/√13
SE = 23.90/3.6056
SE = 6.6286
<em>Hence the approximate standard error of the mean for this sample is 6.63</em>
Use the distance formula to find 2 sides. O through A and O through B.
distance formula is in the image.
OA
root[(x2-x1)^2+(y2-y1)^2]
root[(4-0)^2+(0-0)^2]
root[16]
4
OB
root[(x2-x1)^2+(y2-y1)^2]
root[(0-6)^2+(6-0)^2]
root[36+36]
root[72]

multiply the two numbers and divide by 2.
4 * 6root[2]
24root[2]
24root[2]/2
