Formula for C - 14 dating:
Age = [ ln ( percent/100 ) / ln (1/2 ) ] * 5,730 =
= [ ln ( 0.00921 ) / ln ( 0.5 ) ] * 5.730 =
= [( - 4.68746 ) : ( - 0.6931478 )] * 5,730 =
= 6.7626 * 5,730 = 38,749.56 ≈ 39,000 ( rounded to the nearest thousand )
Answer: The person died about 39,000 years ago.
Answer:
The correct answer is 0.0330 and the events are independent.
Step-by-step explanation:
Total number of balls in Bill's golf bag = 17
Let A be the event of drawing a white ball and B be the event of drawing an orange ball.
Number of white balls Bill has in his bag is 9.
Probability of the event A in the first draw = 
Number of orange ball in Bill's bag is 1.
Probability of event B in the second draw = 
Thus total probability for Tim to tee off with a white ball and putt with an orange ball =
= 0.0330
The above events are independent on each other.
So in 5 acres of land produces 21,000 pounds of strawberries.
Step-by-step explanation:
Step 1:
Last year,
acres i.e 3.5 acres produced 14,700 pounds of strawberries. So we need to determine how many strawberries were produced per acre.
To do this we divide the total number of strawberries produced by the number of acres it was produced in.
The number of strawberries produced per acre
pounds.
Step 2:
To determine the number of strawberries in 5 acres of land, we multiply the number of strawberries per acre by the number of acres.
The number of strawberries produced in 5 acres
pounds.
So in 5 acres of land produces 21,000 pounds of strawberries.
