Answer:
[tex]\frac{1}{233974}[/tex] (1 out of 233974 chance of correctly guessing Alec’s password)
Step-by-step explanation:
First Part (letter in the password):
There are 26 letters in the alphabet, and there is only one letter in Alec’s password. So for that part, you have [tex]\frac{1}{26}[/tex] chance in finding the letter in the password.
Second Part (4 digit number in the password):
For the next part, the problem says that it’s a four digit number. So, out of all the numbers there are, what place value has four digits? It would be the thousands. That means from 1,000 to 9,999 (not including 10,000 too because that’s 5 digits) is the range of all the possible 4 digit numbers. So, how many numbers are in the range of 1,000 through 9,999? Well, all you do is subtract 1,000 from 9,999 (can be written as 9,999 - 1,000) and that equals 8,999. This means that there are 8,999 possible 4 digit numbers that can be guessed in Alec’s password. So that means you will have a 1 out of 8,999 chance in finding the 4 digit number in Alec’s password. This can be written as [tex]\frac{1}{8999}[/tex].
Final Part (solving it):
Finally, you need to multiply the two chances together (the chance in finding the letter times the change of finding the 4 digit number). This can be written as [tex]\frac{1}{26}[/tex] × [tex]\frac{1}{8999}[/tex], which equals [tex]\frac{1}{233974}[/tex].
Answer: [tex]\frac{1}{233974}[/tex] (1 out of 233974 chance of correctly guessing Alec’s password)

Write a function with the following characteristics?
- A vertical asymptote at x = 3
- A horizontal asymptote at y = 2
- Domain: {x=+-3}
9514 1404 393
Answer:
the marked answer (A) is correct
Step-by-step explanation:
The domain restrictions by themselves tell you the denominator of the rational function is ...
(x -3)(x +3) = x² -9 . . . . . matches only choice A
These domain restrictions will give vertical asymptotes at x=±3 if there is no cancelling zero in the numerator.
The horizontal asymptote at y=2 tells you the ratio of leading terms of the numerator and denominator polynomials must be 2. This requirement is also matched by choice A.

Find an angle between 0° and 360° that is coterminal with the angle 2595°.
Answer:
The angle between 0° and 360° that is co-terminal with the angle 2595° is 75°
Step-by-step explanation:
To find the angle between 0° and 360° that is coterminal to a given angle use this rule
The angle that is co-terminal to Ф = Ф - n × 360, where
Ф is the given anglen is the number of the complete turns∵ The given angle is 2595°
∴ Ф = 2595°
→ To find n divide Ф by 360 and equate n by the whole number only
∵ 2595 ÷ 360 = 7.2083333
→ That means the number of complete turns is 7
∴ n = 7
→ Substitute the values of Ф and n in the rule above
∵ The angle that is co-terminal to 2595° = 2595 - 7 × 360
∴ The angle that is co-terminal to 2595° = 2595 - 2520
∴ The angle that is co-terminal to 2595° = 75°
∴ The angle between 0° and 360° that is co-terminal with the angle
2595° is 75°

The ratio of boys to girls at a movie is 4:7. If there are 21 girls, how many boys are at
the movie?
There are
boys at the movie.
Answer: 12 boys at the movie
Step-by-step explanation:
The ratio of boys to girls is 4:7. There are 21 girls at the movie. This is 3 times more than the simplified ratio of girls to boys. Thus, to find the answer, multiply 4 by 3 to get 12 boys at the movie.

the average elecation of new Orleans, Louisiana is -8 feet. the elevation of madras hometown is 8 feet higher then new Orleans.what is the elevation of madras hometown?
Answer:
The elevation of Madras hometown is 0 ft ( representing the surface level elevation)
Step-by-step explanation:
Here, we want to get the elevation of madras hometown
From the question, we are told that Madras home town is 8 feet higher
-8 feet symbolizes a height that is below the surface
Adding 8 to -8 , we have an elevation of -8 + 8 = 0 feet
What this means is that the elevation is exactly at the surface

The graph below compares plant height to the age of the plant, in weeks.
A graph titled Plant Height has Weeks on the x-axis and Height (inches) on the y-axis. A line has a regression equation of y = 1.3 x minus 0.8.
Based on the graph, which is the best prediction of the height of the plant at 5 weeks?
4 inches
5 inches
6 inches
7 inches
Answer:
if you look at the graph and follow up from 5 weeks it almost hits the point 6 inches so you would say six inches the answer is 6 inches
Step-by-step explanation:
The best prediction of the height of the plant at 5 weeks is 6 inches, the correct option is C.
What is a Graph?Graph is a mathematical representation of relation between two objects.
The graph shows the comparison of the plant height to the age of the plant, in weeks.
The x axis has number of weeks.
The y axis has height in inches.
The regression equation that represent the graph is
y = 1.3x - 0.8
A regression equation is used to find the relation between the data, if there exists.
The regression equation is of the form Y = a+bX, Y is the dependent variable and X is the independent variable.
The prediction of the height of the plant at 5 weeks has to be done.
On observing the graph and drawing a straight line at x = 5 on the graph, the point at which it intersects is y ≈ 6 inches.
