Answer:
i think circumference. good luck :D
Step-by-step explanation:
The value of x would be 43°. You would find this by breaking up that side of the line into a sum of 180° (a half circle). Then you would do 180°-47°-90°(which accounts for the sum of degrees of the fourth quadrant) and that = 43°.

Using the z-distribution, it is found that the 90% confidence interval for the true proportion of club members who use compost is (0.392, 0.508).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have a 90% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.645.
The estimate and the sample size are given by:

Hence, the bounds of the interval are:
