Answer: Our required probability is 0.64.
Step-by-step explanation:
Since we have given that
Let A be the event that he upgrades his seat to first class.
Let B be the event that he checks in at least 2 hours early.
Let B' be the event that he does not checks in at least 2 hours early.
So,
By using Bayes' theorem, we get that
Hence, our required probability is 0.64.
Answer:
Width of box is 3 feet
Step-by-step explanation:
Given,
Volume of a box = 30 cubic feet
Length of box= 4 feet
Height of box = 2.5 feet
We need to find width of box.
Since, Volume of box = Length * Height * width
Now plug values for volume, length and height in the above formula and find width.
So,
30 = 4 * 2.5 * Width
30 = 10 * width
Width = 30 /10 = 3 feet
Hence width of box is 3 feet.
The answer would be 4/9 in fraction form
The answer would be 0.4444 in decimal form
Perimeter = 2L + 2W
42 = 2(12) + 2W
42 = 24 + 2W
-24 -24
18 = 2W
/2 /2
9 = W
The answer is 9 feet wide
Answer:
N = 22.5
Step-by-step explanation:
N/6 = 15/4
Using cross products
4N = 6*15
4N = 90
Divide each side by 4
4N /4 = 90/4
N = 45/2
N = 22.5
