Researchers conducted carbon dating on a set of remains to determine if the remains belonged to Caravaggio. The following formula can be used to estimate the age of an artifact using
carbon-14 dating
t = -[In(Nf = No). thalt] = 0.693
In = natural log
t = age of the artifact (in years)
thalf = half-life of carbon-14 = 5,700 years
Nf = amount of carbon-14 found in the artifact
No = amount of carbon-14 found in the living organism before death
If the ratio of Nf to No for an artifact is 0.55, what is the estimated age of the artifact?

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

step-by-step explanation:

the quadrant is facing upwards

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
