Answer:
3/2
Step-by-step explanation:
Finding the perpendicular line to a given line is easy. Find the slope (m) in the equation (directly left to the variable, x). Flip the fraction (or set it over 1 if a whole number), and change the sign to the opposite.
In this case, the perpendicular line's slope will be 3/2.

Hi there! Your answer here is 11kg - the average of the seven weights is 11kg. To find the average of a group of numbers, you add all of the numbers (12, 12, 12, 12, 12, 12, 5), then divide by the count of those numbers (7).
12 + 12 + 12 + 12 + 12 + 12 + 5 (or 12*6 + 5) is equal to 77.
77 / 7 = 11.
So the average of the seven weights is 11kg.
Have a great day! - Mani :)

If an event has a probability P of happening, then there is a probability of (1-P) of the event not happening.
In this case the probability of the event is p=20/69.
Then, the probability of the event not happening is:

Answer: the probability of the event not happening is 49/69.
