Answer:
Yes, the two events are independent because P(NF|PB)=P(NF).
Step-by-step explanation:
Answer:
8.9 meters
Step-by-step explanation:
this seems like a problem where you can use the pythagorean theorem:
you know one of the two legs (6m) and the hypotenuse (9m), you must find the other leg
a^2 + 6^2 = 9^2
a^2 + 36 = 81
a^2 = 45
a = 
or 
· 
which simplifies to be 3 or approx. 8.9 meters
-t-3 and 3-t are not the same since t-3 would result in a negative answer since both -t and -3 are negative. While in t-3 t is positive and -3 is negative. it is wrong if its left as t-3 since -t-3=3-t is false.
It is really easy it is 6
Answer:
x=2
Step-by-step explanation:
Add all the sides to find the perimeter
x+4 + 4x+10(x-1) = 24
Distribute
x+4+4x +10x-10 = 24
Combine like terms
15x -6 = 24
Add 6 to each side
15x-6+6 = 24+6
15x = 30
Divide each side by 15
15x/15 = 30/15
x = 2
