In order from least to greatest:
5/10 , 7/12 , 4/6
You have to find a common denominator of all 3 numbers which is 60 and then you proceed with the next steps.
Sum = 20(1-(1/4)^5) / (1-1/4) = 26.64
Answer:
P(B and B) = 1/9
Step-by-step explanation:
There are 4+3+5 = 12 tiles in total
The probability of selecting a B would be 4/12=1/3
When you are replacing a B tile, planning to pick a B tile again, the total tile count doesn't change. Therefore, because the two events are independent, their probabilities are multiplied and so P(B and B) = P(B) * P(B) = 1/3 * 1/3 = 1/9
Answer:
15
Step-by-step explanation:
4 x __ = 12
the blank would be 3, once you did it on one side you have to do it on the other side too
5 x 3 = 15
Another way you can do it is by...
= 
solve for x (cross multiply)
Answer:
16,383.33 years ( approx )
Step-by-step explanation:
Given equation that shows the amount of carbon-14 after t years,

Where,
= initial amount,
∵ 14% of
=
= 


Taking ln both sides,



Hence, the painting would be 16383.33 years old ( approx )
