To figure out the answer, you must first find the area. To do this, multiply the length times the width. In this case, that is 7 feet times 8 feet. That equals 56 feet squared. Because the square paving stones are 1 foot squared, the answer is 56 paving stones in all.
I hope this helped! If you don't mind, please do mark my answer as the Brainliest, as I am trying to get past the Ambitious rank. :)
Answer:
The expected number of floors the elevator stops at, not counting the ground floor is =
n*(1-(1-1/n)^m)
Step-by-step explanation:
Here, we want to know the expected number of floors the elevator stops at.
let X1,X2,X3,..Xn are indicator variable for which value =1 if at least one person stops on that floor otherwise value is 0
P(at least one person stops at floor Xj)=1-P(none of m people stops at floor j)
=1-(1-1/n)^m
here total number of floors on elevetor Stops X=X1+X2+X3+...+Xn
hence expected number of floors on elevetor Stops
E(X)=E(X1)+E(X2)+E(X3)...+E(Xn)
=(1-(1-1/n)^m )+(1-(1-1/n)^m )+(1-(1-1/n)^m )+(1-(1-1/n)^m )+..... n times
=n*(1-(1-1/n)^m)
Answer:
x=3, y=1. (3, 1).
Step-by-step explanation:
x+3y=6
4x-6y=6
------------
simplify 4x-6y=6 into 2x-3y=3
------------------------
x+3y=6
2x-3y=3
--------------
3x=9
x=9/3
x=3
3+3y=6
3y=6-3
3y=3
y=3/3
y=1
