so the cosine is 3/5 B
The answer is 5 and 6
Hope this helps
Answer:
Step-by-step explanation:
J is correct.. that function can never be less than 2
To find the standard error, divide the standard deviation by the square root of the sample size
standard deviation = 7.5
sample size = 25......sqrt 25 = 5
standard error = 7.5 / 5 = 1.5 <==
