A code consists of eight letters chosen from the 26 letters of the alphabet. What is the chance that any two of the letters are the same?
Answer:
1/26 or 0.039 (approximate to 3 decimal places)
Step-by-step explanation:
A code consists of 8 letters of the English alphabet (which comprises a total of 26 distinct letters). What is the chance or probability that any 2 letters of/in the code are the same?
An example of such code with a repeated letter is GREENMAN.
This word (code) has 2 letters that are the same and that's letter 'E'.
The probability that a letter in the code in question will appear twice depends on the frequency of appearance of that letter in the English alphabet set.
Now, no letter in the English alphabet set appears twice! Because of this, every letter in the English alphabet has an equal probability of being picked to form a code or word.
Hence, the chance that any letter from the alphabet will be repeated once in this code (same as saying the chance that any two letters of the code are the same) is 1/26 and that's equal to 0.03846 ≅ 0.039

Find the area of each figure. around to the nearest tenth if necessary.
Answer:
68 cm²
Step-by-step explanation:
I don't see what you mean for each figure but here goes nothing!
We can split the figure in 2 rectangles
We find the first rectangle by doing 4 x 12 = 48 cm²
The second rectangle would be 5 x 4 = 20 cm²
Therfore we add them up into 20 + 48 = 68 cm²
Hope This Helps!

Find the slope of the line that contains the following pair of points: (1, 2), (5, 2).
A. -1
0
B. 0
C. 4
D. Undefined
Answer:
B. 0
Step-by-step explanation:
2-2/5-2= 0/3= 0
Another way to look at this is that because they have the same y coordinate, it must simply be a horizontal line, which has a slope of 0
Bus A and Bus B leave the bus depot at 3 pm.
Bus A takes 25 minutes to complete its route once and bus B takes 30 minutes to complete its route once.
If both buses continue to repeat their route, at what time will they be back at the bus depot together?
Assume the buses have no breaks in between routes.
Give your answer as a 12-hour clock time.
Step-by-step explanation:
Bus A leave depot at = 3pm
Bus B leave depot at = 3 pm
both leave depot at 3 pm so
Bus A complete its route in25 mins
Bus A reach at his point at 3:25 pm
Bus B complete its route in 30 mins
Bus B reach at his point at 3:30 pm
So
If the buses go back to depot it will take 25 mins so Bus A reach back at depot at 3:50 pm
Bus B at 4:00 pm
A flower bed is 3 meters wide and 6 meters long. What is the area of the flower bed in square feet? Round intermediate calculations and your answer to the nearest hundredth.
Answer:
193.75 square feet or 193.75 ft²
Step-by-step explanation:
A flower bed is 3 meters wide and 6 meters long.
From the question , our final answer is to be in square feet.
Hence:
Step 1
We convert dimensions to feet
For width
= 3 meter
1 meter = 3.28084 feet
3 meter = x
x = 3 × 3.28084 feet
x = 9.84252 feet
For Length
= 6 meter
1 meter = 3.28084 feet
6 meter = x
x = 6 × 3.28084 feet
x = 19.685 feet
Step 2
We calculate the area of the flower bed
The formula is given as:
Length × Breadth
Hence: 9.84252 feet × 19.685 feet
= 193.7500062 square feet
Approximately to the nearest hundredth = 193.75 square feet or 193.75 ft²
The area of the flower bed in square feet is 193.75 square feet or 193.75 ft²

Parks department ordered a total of 100 bats and balls. The bats are $20 and balls are $4.50 each. The total invoice was $822.00 . How many of each item were ordered?
Answer:
Number of bats ordered = 24
Number of balls ordered = 76
Step-by-step explanation:
Let,
x be the number of bats ordered
y be the number of balls ordered
According to given statement;
x+y = 100 Eqn 1
20x+4.50y = 822 Eqn 2
Multiplying Eqn 1 by 20
20(x+y=100)
20x+20y=2000 Eqn 3
Subtracting Eqn 2 from Eqn 3
(20x+20y)-(20x+4.50y)=2000-822
20x+20y-20x-4.50y=1178
15.50y = 1178
Dividing both sides by 15.50
[tex]\frac{15.50y}{15.50}=\frac{1178}{15.50}\\y=76[/tex]
Putting y=76 in Eqn 1
x+76 = 100
x= 100-76
x = 24
Hence,
Number of bats ordered = 24
Number of balls ordered = 76

Does the point(1, 8)satisfy the inequality y ≥ 7x + 1?
Answer:
Yes
Step-by-step explanation:
Plug in the point (1,8)
y=8, x=1
8≤7(1)+1
8≤7+1
8≤8
Answer:
Yes.
Step-by-step explanation:
y ≥ 7x + 1.
Plug the values in:
y = 8
7x + 1 = 7(1) + 1 = 8
As the inequality sign is ≥ then the point (1, 8) satisfies it.
