Hey there :)
Let
p represent the number of bags to be bought
We need to collect
30 stickers and each
bag has
3 stickers
3p = 30
↑ ↑
Number of stickers in a bad Number of stickers to be collected

=
p = 10We need to buy 10 bags of crisps to have 30 stickers
Answer:

Step-by-step explanation:
Assuming conditions are met, the formula for a confidence interval (CI) for the difference between two population proportions is
where
and
are the sample proportion and sample size of the first sample, and
and
are the sample proportion and sample size of the second sample.
We see that
and
. We also know that a 98% confidence level corresponds to a critical value of
, so we can plug these values into the formula to get our desired confidence interval:

Hence, we are 98% confident that the true difference in the proportion of people that live in a city who identify as a democrat and the proportion of people that live in a rural area who identify as a democrat is contained within the interval {-0.2941,-0.0337}
The 98% confidence interval also suggests that it may be more likely that identified democrats in a rural area have a greater proportion than identified democrats in a city since the differences in the interval are less than 0.

Hello!
The sin of D would be the opposite side divided by the hypotenuse. As we have no hypotenuse length, neither A or D would work, as the cosine also involves the hypotenuse.
The tangent is the opposite divided by the adjacent. This would be, in terms of D, 24/31. This does not match our option.
In terms of K, the tangent is 31/24.
Therefore, our answer is C) tanK= 31/24
I hope this helps!
