Alec's password consists of 1 letter and 4 digits. What is the probability of correctly guessing Alec's password?
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)

please only answer if you know :)
Answer:
True
Step-by-step explanation:
Consciousness means a state of mind in which one is aware of the surrounding and himself. The one who is aware of his mind, thoughts, and the environment near him is called a conscious person. In consciousness a person is fully aware of his desires, wishes and surrounding circumstances. Consciousness is more about thought, feelings, neuroscience psychology, cognitive development. If one needs to be civilized he must be aware of the disciplines and thought process he is living in. It is an exclusive part of civilizations as your mental health defines your social health.The altered state of consciousness is that person starts being uncivilized by consuming alcohol and drugs. We can say so that consciousness appears to be an exclusive feature of organisms that develop civilization.
For example, a boss scolding an employ also makes the employ angry but the employ politely accepts his mistake and apologize for the same in order to act in a civilized manner. So, in order to be civilized the person must act wisely with people present in his surrounding.
As a result, we can conclude that the statement: consciousness appears to be an exclusive feature of organisms that develop civilizations, is true.

Kenny is thinking of two numbers greater than 10.
"The highest common factor (HCF) of my two numbers is 7
The lowest common multiple (LCM) of my two numbers is 84”
He says:
Write down the two numbers that Kenny is thinking of.
Highest common factor is the greatest factor between two or more number. Least common factor least number which is divisible by two numbers.The two numbers that Kenny is thinking of are 21 and 24.
Given-
The least common factor (HCF) of the two numbers is 7.
The highest common factor (LCM) of the two numbers is 84.
The two number are greater than 10.
Highest common factorHighest common factor is the greatest factor between two or more number.
Least common factorLeast common factor least number which is divisible by two numbers.
As the number is LCM is 7, thus the number must be the multiple of 7. Both the number are greater than 10. Thus the possible number should be greater than 14(multiple of 7 and greater than 10) and less than 84 ( LCM is 84).
The possible number for the above condition are,
14,21,28,35,42,49,56,63,70,77 and 84.
Both the number must divide the number 84. In the above number only 14,21,28,42 and 84 can divide the number 84.
The product of both the number must be equal to the product of the HCF and LCM. The product of the HCF and LCM,
[tex]=84\times6=504[/tex]
From the above possible points only the product of 21 and 24 is equal to the 504.
Thus the two numbers that Kenny is thinking of are 21 and 24.

The domain of rational function g is the same as the domain of rational function f. Both f and g have a single x-intercept at x = -10. Which equation could represent function g?
A.
g(x) = 10f(x)
B.
g(x) = f(x + 10)
C.
g(x) = f(x) + 10
D.
g(x) = f(x) − 10
Answer:
A
Step-by-step explanation:
We know that both functions f and g have a single -intercept at x = -10.
Therefore, when transforming f, we should not have any vertical/horizontal translations as this will shift g away from the zero at x = -10.
For B, this is a horizontal translation of 10 units to the left.
For C, this is a vertical translation of 10 units upwards.
And for D, ths is a vertical translation of 10 units downwards.
Therefore, the only choice that does not represent a vertical/horizontal translation is A.
A is f vertically strectched by a factor of 10.
This will not affect the zeros of f and g.
You can picture this using the parent parabola function: y = x².
If we shift this vertically or horizontally, the zeros will change.
However, any vertical shift such as y = 2x², y = 10x², or even y = 100x², the zero will still remain at x = 0.
Answer:
A. g(x) = 10f(x)
