How much time until your castle is destroyed? Suppose you decide to build your castle at the average
waterline, just as the tide goes below the average
waterline. How long will you have to build your castle
before the tide rises back up to the average waterline
and destroys your work?
Use the graph to determine your answer. Use complete
sentences and appropriate units to give your answer.
Explain (using specifics) how you used the graph to
determine your answer.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
