Answer:
75%
Step-by-step explanation:
44*75% = 33
Answer:
I would reject the null hypothesis because it falls outside of the 95% confidence interval.
The mean would be 7 I think I am not sure
Answer:
That would be sina.
Step-by-step explanation:
sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
Adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
