Answer from: leeorareeves299

There is 10 digits to choose from and 26 letters.

Multiply the 3 choices together for total combinations: 10 x 10 x 26 = 2600.

The probability pf picking the first digit would be 1/10

The probability of picking the 2nd digit would also be 1/10

The probability of picking the letter would be 1/26

Answer from: savagesquid4807

If repetition is allowed then the number of ways of making a pass code = 2600

The probability of choosing the first digit correctly = $\dfrac{1}{10}$ The probability of choosing the second digit correctly = $\dfrac{1}{10}$ The probability of guessing letter correctly = $\dfrac{1}{26}$ The probability that you would guess Hector's passcode correctly on the first try = $\dfrac{1}{2600}$

Step-by-step explanation:

Given: An extra security pass-code for a certain account is made up of 2 digits followed by 1 letter.

The number of choices for first and second place =10

The choices for the third place 26

If repetition is allowed then the number of ways of making a pass code is given by :-

$10\times10\times26=2600$

The probability of choosing the first digit correctly = $\dfrac{1}{10}$

Similarly , the probability of choosing the second digit correctly = $\dfrac{1}{10}$

The probability of guessing letter correctly = $\dfrac{1}{26}$

If we choose the digits and letters randomly , then the probability that you would guess Hector's passcode correctly on the first tr4=y is given by ;-

$\dfrac{1}{10}\times\dfrac{1}{10}\times\dfrac{1}{26}=\dfrac{1}{2600}$

Answer from: Quest

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
