Answer:
X=35
Step-by-step explanation:
Angle M= 60 <-- because we know a triangle=180 and so far we have 40 and 80 in the triangle JKM, 60 degrees is needed to complete 180
The other side of angle M (in the triangle KML)= 120 <-- because we know that a straight edge is 180 degrees and to complete the 180, we need another 120 degrees
so, to find X we need to find how many degrees are needed to complete the 180 degrees of triangle KML
120+25= 145
180-145= 35

Step-by-step explanation:
The solution would be like this for this specific problem:
Given:
N = 256
Sample Mean = $35,420
Standard Deviation = $2,050
Find:
Standard Error of Mean = ?
The
formula for the standard error of the mean is:
<span>Om
= o / sqrt(N)</span>
<span>Om
= the </span>standard deviation of the sampling
distribution of the mean
where
o = standard deviation of the sampling distribution of a statistic
N
= sample size
<span>So
substituting the formula with the given:
Om = $2,050 / sqrt(256)</span>
<span>Om
= $2,050 / 16</span>
= $128.125
Therefore, the sample standard error of the mean is
$128.125.
height = 7 miles, base dimension is 190 miles
to find the angle on the ground up to the plane
use arctan(7/190)
acrtan on a calculator is tan^-1
arctan(7/190) = 2.1099 degrees. Round off as necessary
