Answer:
Step-by-step explanation:
Formula:
Using Victoria's simulation :
Total number of outcomes = Total number of times marbles rolled x Total number of times coin flipped
= 50 x 50 =2500
Favorable outcomes = Total number of times pulling a blue marble and the coin landing tails up
= Number of times blue marble rolled x Number of times coin flipped to tail
= 18 x 30=540
Now, the the probability of pulling a blue marble and the coin landing tails up will be :-
Answer:
C. 540/2500
Step-by-step explanation:
18 times 30=540
50 times 50= 2500
Answer:
Subtract ax from both sides. ax + by − ax = c − ax.
Simplify. by = c − ax.
Divide both sides by b ; b ≠ 0. by b = c b − ax b ; b ≠ 0.
Simplify. y = c − ax b ; b ≠ 0.
Answer:
Step-by-step explanation:
If you simplify you get 0 = 19/3, which is false. So there is no solution.
Answer:
7892 dolphins
Step-by-step explanation:
let P denote the dolphin population.
-Notice this is an exponential decay and is denoted as:
Where;
#Given t=30yrs, =20000 and r=3.1%, the population after 30 years is estimated as:
Hence, the dolphin population after 30yrs is approximately 7892
