To find the probably and at least on you must find the probability of none and subtract from one.

The probability of none can be found like so:

(5+6 over 5+6+7)^3 = .228

1 - .228 = .772

If the product of two positive consecutive odd integers is 63, what’s the larger number ?
myrzilka [38]

For this case we have:

x: Let the variable representing the first odd number

x + 2: Let the variable representing the consecutive odd number at x.

According to the statement we have:

x (x + 2) = 63\\x ^ 2 + 2x = 63\\x ^ 2 + 2x-63 = 0

We found the solution by factoring:

We look for two numbers that, when multiplied, result in -63 and when added, result in 2. These numbers are +9 and -7.

9-7 = 2\\9 * (-7) = -63

Thus, we have:

(x + 9) (x-7) = 0

Therefore the solutions are:

x_ {1} = - 9\\x_ {2} = 7

We choose the positive value, so we have:

x = 7\\x + 2 = 7 + 2 = 9

Answer:

The largest number is 9

The recommended density of a rectangular aquarium is 7 fish per cubic foot of water. If the owner of the aquarium follows the re
TiliK225 [7]

Answer: 2 feets

Step-by-step explanation:

Recommended density = 7 fish/ ft^3

If recommended density guideline is followed:

Number of fishes in aquarium = 42

Length of aquarium = 3ft

Width = 1ft

Height =?

Volume of aquarium = Length × width × height

Volume = 3 × 1 × h = (3ft^2 × h)

Therefore ;

If

1ft^3 = 7 fishes

x ft^3 = 42 fishes

Cross multiply

7(x)ft^3 = 42 fishes

x ft^3 = (42÷7)

x ft^3 = 6

Therefore volume of the aquarium with 42 fishes is 6ft^3

Volume = (3ft^2 × h)

6ft^3 = 3ft^2 × h

h = (6ft^3) / (3ft^2)

h = 2ft
