Step-by-step explanation:
Ratio of short length to hypotenuse
= cos60
= 1/2
Answer:
A
Step-by-step explanation:
So we have the two functions:
And we want to find:
This is the same as:
So, to find the answer, find g(1) first:
Now, substitute this value for g(1):
And plug this into f(x):
Therefore:
Our answer is A
Margin of error, e = Z*SD/Sqrt (N), where N = Sample population
Assuming a 95% confidence interval and substituting all the values;
At 95% confidence, Z = 1.96
Therefore,
0.23 = 1.96*1.9/Sqrt (N)
Sqrt (N) = 1.96*1.9/0.23
N = (1.96*1.9/0.23)^2 = 262.16 ≈ 263
Minimum sample size required is 263 students.
