irina [24]
For this we will use formula that is letting us to input: interest rate, starting funds, how often intereset rate is implemented, period we are observing. Formula looks like this:

M = S(1+ \frac{i}{cp})^cp*y

where M is money, S is starting funds, "i" is interest rate, cp is compounding period and y is number of years. now we express and calculated for both of them and get

M = 318,479 for Patricks investement.

M = 331,482 for Brooklyn.

Which means Brooklyn's method will pay of more.

Black_prince [1.1K]
Probability =  \frac{number of choice}{total number of choices}
# green = 20
# orange = 44
# blue = 30
Total = 20 + 44 + 30 = 94

P(green) =  \frac{20}{94} =  0.212

P(orange) =  \frac{44}{94} = 0.468
P(blue) =  \frac{30}{94} = 0.319

Strike441 [17]
<h2>Answer with explanation:</h2>

Given : An urn contains 2 red marbles and 3 blue marbles.

Total marbles = 2+3=5

a) The general ways in which the person could get a red marble and a blue marble are :

1)  He draws red marble first and then second marble as blue.

2)  He draws blue marble first marble and then second marble as red.

b)  The number of ways to get one red and one blue marble is given by :-

^2C_1\times^3C_1=2\times3=6                          (i)

c) Number of ways to get 2 marbles from 5 is given by :-

^5C_2=\dfrac{5!}{2!(5-2)!}=\dfrac{5\times4\times3!}{3!\times2}=10     (ii)

Now, The probability the person gets a red and a blue marble will be :-

P(R\ \&B)=\dfrac{6}{10}=0.6       [Divide (i) by (ii)]

Hence, the  probability the person gets a red and a blue marble= 0.6

The aquarium has 10 more red fish than blue fish. 60 percent of the fish are red. How many blue fish are in the aquarium?
guajiro [1.7K]

Answer:

20 blue fish

Step-by-step explanation:

Number of blue fish = x

Number of red fish = x+10

Red fish = 60% of total = 0.6

Total fish = x+x+10 = 2x+10

0.6 = (x+10)/(2x+10)

Solve for x:

1.2x+6 = x+10

0.2x = 4

x = 20

Hope this helps!
