so the probability of pulling out a blue marble on the second go is 13/52
"13" is the original number of blue marbles added after selecting the black marble
"52" is me simply add up all the marble in the bag..the 14 red marbles, 26 black marbles minus the 1 pulled out and not replaced so now its 25 and the 13 blue marbles added last.
Final answer:
The question relates to sequential probability. A black marble must be picked first to add blue marbles to the pot. The combined probability of these events is 169/1040.
Explanation:
The subject is probability within mathematics. In order to determine the probability of picking a blue marble as the second marble, it is important to understand that this can only happen if a black marble was chosen first (because blue marbles are only added after a black marble is chosen). Initially, we have 14 red marbles and 26 black marbles. Therefore, the probability of picking a black marble first is 26/40.
After the first black marble is chosen, 13 blue marbles are added, making the total number of marbles 53. As a result, the probability of picking a blue marble as the second draw is 13/53.
Since these are sequential events, we multiply the probabilities together. Therefore, the probability of the second marble being blue is (26/40) * (13/53), which simplifies to 169/1040 or approximately 0.1625.

2_4/9 * 2_4/9
Mixed numbers cannot be multiplied, so first convert to improper fractions:
(9*2)+4 = 18+4 = 22/9
22/9 * 22/9
Multiply straight across:
(22*22)/(9*9) = 484/81
Now turn this into a mixed number:
81 goes into 484 five times with 79 left over:
5_79/81 square inches

Answer:
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Step-by-step explanation:
Given that a roller coaster ride reach a height of 80 feet.
The height above the ground of the roller coaster is modeled by the function
h(t)=10t²-40t+80
where t is measured in second.
h(t)=10t²-40t+80
Differentiating with respect to t
h'(t)= 10(2t)-40
⇒h'(t)=20t-40
To find the minimum height we set h'(t)=0
∴20t-40=0
⇒20t =40
⇒t=2
The height of the roller coaster minimum when t=2 s.
The minimum height of of the roller coaster is
h(2)= 10(2)²-40.2+80
=40-80+80
=40 feet.
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
