Jason observed a large art sculpture in a local park and wanted to know its height, but the sculpture was much taller than he could
measure. Jason measured the length of the shadow of the sculpture's highest point to be 15 feet long
If the top of a slide in the same park, measured at the same time of day, has a height of 90 inches and a shadow length of
54 inches, how tall is the art sculpture at its highest point?

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

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;
