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:

Answer:
39
Step-by-step explanation:
DGM and YGR are vertical angles so set them equal to each other and once you have d, substitute it into DGM

Both figures are rhombuses, they have the same angle degrees, one is just slanted more and smaller than the other.
Answer:
17.5 meters
Step-by-step explanation:
To find how far she walks, multiply 2.5 by 7
2.5(7)
= 17.5
So, in 7 days, she walks 17.5 meters
