Answer:
5/12
Step-by-step explanation:
Assuming the each number is equally likely
1,2,3,4,5,6,7,8,9,10,11,12
There are 12 numbers on the spinner
Number less than or equal to 5: 1,2,3,4,5
There are 5 choices
P ( # < = 5) = Number less than or equal to 5/ total
=5/12
(x-y)^2 +4xy = (x+y)^2
FOIL
x^2 -2xy+y^2 +4xy = (x+y)^2 x^2 -2xy
Combine like terms
x^2 +2xy +y^2 = (x+y)^2 x^2 +2xy
Factor
(x+y)^2 = (x+y)^2 (x+y)^2
C
Add 1 to both sides:
2t > 16
Divide 2 to both sides:
t > 8
469,225
685² = 469,225
I hope this helps!
