The correct answer is the 3rd choice:
4/12 x 3/11
The explanation is that to start there are 12 total eggs of which 4 of them are boiled, so there is a 4/12 chance that the chef will get a hard boiled egg.
After removing one of the hard boiled eggs, there will be 3 hard boiled eggs remaining and one less total eggs (11).
To find the probability of getting a hard boiled egg both times, you multiply both probabilities together.
Answer:
y = -1
Step-by-step explanation:
1/2 of 4y + (y + 3) = 0
1/2 X 4y + (y + 3) = 0
4y/2 + (y + 3) = 2y + y + 3 = 0
3y = -3
∴ y = -1
Answer:
$5.49
Step-by-step explanation:
What we have:
3 dollars = $3.00

$5.40 + $0.09
$5.49 in total

Answer:
Width is 18 inches
Perimeter is 99 inches
Area is 567 square inches
Step-by-step explanation:
The ratio of width to length is 4 : 7
The length is 31.5 inches
The width = (31.5 ×4) ÷ 7 = 18 inches
Perimeter = 2(length + width)
Perimeter = 2(31.5 + 18) inches = 99 inches
Area =length × width
Area = 31.5 inches × 18 inches = 576 square inches.
