Have The Shroud of Turin, which shows the negative image of the body of a man who appears to have been crucified, is believed by many to be the burial shroud of Jesus of Nazareth. In 1988 the Vatican granted permission to have the shroud carbon-dated. Three independent scientific laboratories analyzed the cloth and concluded that the shroud was approximately 660 years old,t an age consistent with its historical appearance. Using this age, determine what percentage of the original amount of C-14 remained in the cloth as of 1988. (The half-life of C-14 is approximately 5730 years. Round your answer to the nearest percent.) in the clothn

94%

Step-by-step explanation:

Half life of a radioactive element is the time taken for half it's mass to disintegrate away.it means after attaining half life,what will be left is 100-50=50%.

Let the 100% mass of C-14,be x

Then 5730years=1/2 of X

Then 660 years=y of X

Where Y is the fraction of C-14 that has disintegrate as at 1988.

5730/660=1/2X/yX

5730/660=1/2/y

Cross multiplying

5730×y=660×1/2

5730y=330

Y=330/5730=0.05759

In %,5.76%

Amount of C-14 left is

100-5.76=94.24=94% as at 1988.

3/56

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that two marbles are drawn without replacement from a box with 1 blue, 3 white, 2 green, and 2 red marbles.

The total number of marbles in the box

= 1 + 3 + 2 + 2

= 8 marbles

The probability that the first marble is white and the second marble is blue

= 3/8 * 1/7

= 3/56
