Answer: 90
Explanation: The pattern is add 3 then the next set is double. [9-6=3 then 18-9=9(or doubled)] and the pattern continues and because 45-42=3 the next number set would be 45 doubles which equals 90.
Hancock building * .27 = 92 m
divide each side by .27
Hancock building =92/.27
Hancock building =340.740(repeating)
Answer: the building is approximately 340.74 meters
100 x 100............. = 10 000
Answer:
Mean is 0.6.
Standard deviation is 0.059
Step-by-step explanation:
The first step is finding the sample proportion p.
Suppose Maria, a researcher, takes a random sample of 70 Americans and finds that 42 are over the age of 20.
This means that
What are the mean and standard deviation of the sampling distribution of p?
Mean:
The mean of a proportion is the same as the proportion. So the mean is 0.6
Standard deviation:
Proportion p in a sample of size n. The standard deviation is:
Sample size 70, so:
