Answer and Step-by-step explanation:
To calculate a confidence interval for a proportion:
1) Determine the proportion
p = 0.616
2) A 90% confidence interval has z-score that is 1.645.
3) Calculate margin of error
where
n is the sample size
So
ME = 0.02175
Then the interval is given by
p ± z(ME)
0.62 ± 1.645(0.02175)
0.62 ± 0.035
The interval will be
0.585 < p < 0.655
What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.
Step-by-step explanation:
what you did was you multiplied all numbers (incl. pi as number) :
1/6, pi, 1/12, pi
and that gives 0.137077839. no i or pi attached. just the plain result number.
so, if you need to just calculate the factors of pi, but don't need the fully numeric result, then your problem looks like
1/6 × pi × 1/12 × pi = 1/72 × pi²
so, you have an expression of pi² with a factor of 1/72.
you only need to type in all the factors, not pi itself (that's what you need to add at the end yourself).
Answer:
b
Step-by-step explanation:
you add each of the drinks together from each store
then you match up the numbers and see if the answer matches each number you added
70 + 30 + 100 = 200
80 + 50 + 110 = 240
50 + 60 + 90 = 200
30 + 40 + 10 = 80
= b
