Answer:
8
Step-by-step explanation:
Probability for the first and second years separately is 0.18, so together they are 0.18²=0.0324 or 3.24%.
3 x 1.5 = 4.5 and positive, negative
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.
Answer: at the values where cos(x) = 0Justification:1) tan(x) = sin(x) / cos(x).
2) functions have vertical asymptotes at x = a if Limit of the function x approaches a is + or - infinity.
3) the limit of tan(x) approaches +/- infinity where cos(x) approaches 0.
Therefore, the grpah of y = tan(x) has asymptotes where cos(x) = 0.
You can see the asympotes at x = +/- π/2 on the attached graph. Remember that cos(x) approaches 0 when x approaches +/- (n+1) π/2, for any n ∈ N, so there are infinite asymptotes.
