I am not sure of the correct answer but cross multiply to find which has the bigger number and smallest to put them in order.
Answer:
(0.4958, 0.7422)
Step-by-step explanation:
Let p be the true proportion of water specimens that contain detectable levels of lead. The point estimate for p is . The estimated standard deviation is given by . Because we have a large sample, the 90% confidence interval for p is given by where is the value that satisfies that above this and under the standard normal density there is an area of 0.05. So, the confidence interval is , i.e., (0.4958, 0.7422).

The depth; or, height, "h"; would represent the "radius", "r" .
So, the volume would be:

Answer: 24 miles.
Step-by-step explanation:
1. You must keep on mind that, according the scale on the map, 1.5 inches represents 4 miles. Then, you can set up the following ratio:
Where x is the number of actual miles asked
2. You must solve for x, as following:
3. Therefore, 6 inches on the map represents 24 miles.
