Answer:
$186.86
Step-by-step explanation:
<u>4 eggs cost:</u>
1 dollar per dozen (12 eggs), so by unitary method (ratios), we can find cost of 4 eggs. Shown below:
So, 4 eggs cost $0.33 approx
<u>12 lb. flour cost:</u>
2.50 dollar per pound, so 12 pounds would simply cost:
2.5 * 12 = $30
<u>14 lb of sugar cost:</u>
4.50 dollar per pound means 14 pounds would cost:
4.5 * 14 = $63
<u>2 ready-made edible flowers cost:</u>
5 cents for each flower means 2 flowers would cost:
5 cent = 0.05 dollars
0.05 * 2 = $0.10
We add all up to find cost of 1 cake. Shown below:
Cost of 1 cake = $0.33 + $30 + $63 + $0.10 = $93.43
Cost of 2 cakes = $93.43 * 2 = $186.86
Answer:
Step-by-step explanation:
Let x be a random variable representing the flight arrival time from Boston to New York.
For a uniform probability distribution, the notation is
X U(a, b) where a is the lowest value of x and b is the lowest value of x
The probability density function, f(x) = 1/(b - a)
Mean, µ = (a + b)/2
Standard deviation, σ = √(b - a)²/12
From the information given, the time difference in minutes is 9:57 - 9:07 = 50 minutes. Therefore,
a = 0
b = 50
µ = (0 + 50)/2 = 25
σ = √(50 - 0)²/12 = 14.43
b) converting to minutes, it is 9:30 - 9:07 = 23 minutes
the probability that a flight arrives late(later than 9:30 am) is expressed as P(x > 23)
f(x) = 1/(50) = 0.02
P(x > 23) = (50 - 23)0.02 = 0.54
