Answer:

\frac{1}{233974} (1 out of 233974 chance of correctly guessing Alec’s password)

Step-by-step explanation:

<u>First Part (letter in the password):</u>

There are 26 letters in the alphabet, and there is only one letter in Alec’s password. So for that part, you have \frac{1}{26} chance in finding the letter in the password.

<u>Second Part (4 digit number in the password):</u>

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 \frac{1}{8999}.

<u>Final Part (solving it):</u>

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 \frac{1}{26} × \frac{1}{8999}, which equals \frac{1}{233974}.

<u>Answer:</u> \frac{1}{233974} (1 out of 233974 chance of correctly guessing Alec’s password)

I hope you understand and that this helps with your question! :)

If m angle abf=7b-24 and m angle abe=2b find m angle ebf
cricket20 [7]

angle ABE is equivalent to the whole angle, and it measures 2b. <span>
while the angle ABF is only a portion of angle ABE, and it measure 7b - 24. 

<span>since we know the measure of the whole angle and a part of the angle, we can then subtract to find the left over angle (angle EBF), so

Angle EBF = Angle ABE - Angle ABF </span></span>

Angle EBF = 2b – (7b – 24)

<span>Angle EBF = 24 – 5b</span>

Tanya [424]

Answer:

C

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = \frac{a_{2} }{a_{1} } = \frac{\frac{10}{3} }{10} = \frac{10}{3} × \frac{1}{10} = \frac{1}{3} → C
