Find the midpoint of the segment with endpoints at A(3, 11) and B(7,3).

bonufazy [111]

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(3, 11) and B(7,3)

The midpoint is

$M = ( \frac{3 + 7}{2} \: , \: \frac{11 + 3}{2} ) \\ = ( \frac{10}{2} \: , \: \frac{14}{2} )$

We have the final answer as

A thief steals an atm card and must randomly guess the correct three digit pin code from a 9 key keypad repetition of digits is

marissa [1.9K]

Answer:

1/729

Step-by-step explanation:

Assuming that the probabilities of each digit in the pin is independent from the other digits, the answer to this question can be calculated. There are total of 9 digits, out of which 1 digit is correct. This is true for all the three digits. So the probability of choosing the correct digit in the first place in the first try will be 1/9. Since this is true for the rest of the digits as well and they are independent, we can safely multiply the probabilities. So P(Correct Guess in the first try) = 1/9 (first place) * 1/9 (second place) * 1/9 (third place) = $1/9^3$ = 1/729. So the correct answer is 1/729!!!
