A basket is filled with 8 white eggs and 10 brown eggs. Half of the white eggs are cracked.

probability ( cracked given it is white egg) = \frac{P  ( cracked- and - white egg) }{P(white egg)}

White eggs = 8

Brown eggs = 10

Total eggs = 18

cracked eggs = half of white eggs = 4

Probability (cracked and white egg) = \frac{4}{18}

Probability ( white egg) = \frac{8}{18}

probability ( cracked given it is white egg) = \frac{\frac{4}{18}}{\frac{8}{18}}

=  \frac{4}{8}   =  \frac{1}{2}

The probability that it is a cracked, white egg is \frac{1}{2}

<em>Aquarium will hold 4.4 * 2.5 * 5.3 = 58.3 cubic feet of sea water.</em>

<em>For 3 cubic feet of sea water, weight is 192 pounds</em>

<em>For 58.3 cubic feet of sea water,</em>

<em>( 192 * 58.3) / 3 = 11193.6 / 3 = 3731.2 pounds</em>

What are the dimensions of a rectangle with an area of 12 square cm and a perimeter of 14 cm?
kow [346]

Answer:

For the rectangle

Length=ℓ

Breadth=b

Area is 12 cm2

ℓb=12

Perimeter is 16 cm

2(ℓ+b)=16

ℓ+b=8

Substitute b=12ℓ from first equation

ℓ+12ℓ=8

ℓ2+12=8ℓ

ℓ2−8ℓ+12=0

Use quadratic formula (x=−b±√b2−4ac2a) to find ℓ

ℓ=−(−8)±√(−8)2−(4×1×12)2×1

ℓ=8±√162

ℓ=8±42

ℓ1=8+42=6

ℓ2=8−42

Step-by-step explanation:

For the rectangle

Length=ℓ

Breadth=b

Area is 12 cm2

ℓb=12

Perimeter is 16 cm

2(ℓ+b)=16

ℓ+b=8

Substitute b=12ℓ from first equation

ℓ+12ℓ=8

ℓ2+12=8ℓ

ℓ2−8ℓ+12=0

Use quadratic formula (x=−b±√b2−4ac2a) to find ℓ

ℓ=−(−8)±√(−8)2−(4×1×12)2×1

ℓ=8±√162

ℓ=8±42
