Answer:

No

Step-by-step explanation:

They are independent iff:

P(F & D) = P(F) × P(D)

A rectangular deck is 9 meters long by 7 meters wide. What is the length someone would walk
Feliz [49]

Answer:

11.4 metres

Step-by-step explanation:

Use Pythagoras theorem for a right-angled triangle

a^2 + b^2 = c^2

if you cut the rectangle in half, it will become a right angled triangle.

a and b are two sides of the rectangle, while c is the diagonal or hypothenuse

so 9^2 + 7^2 = c^2

81 + 49  = c^2

c^ 2 = 130

square root 130 = c

you should get approximately 11.4 metres
