The probability is 1/7.
If the Captain shoots first, there is a 1/2 chance she will miss the pirate. Since the pirate ship was not hit, there is a 2/7 chance she will hit the Captain. The total probability is 1/2(2/7) = 2/14 = 1/7.
1/3; 39%; 2/5; 0.42
hope this helps!
Distributive is
a(b+c)=ab+ac
ab+ac=a(b+c)
perimiter of a rectangle=distance around
we have
P=L+W+L+W if we go around
so
P=L+L+W+W
P=2L+2W
undistribute 2
P=2(L+W)
X(2x²-9x+10)=x(2x-5)(x-2)=0.
x=0 is one solution.
2x-5=0 and x-2=0 give us the solutions x=5/2 and x=2.
So x=0, 2 or 5/2.
Answer:
x and y = (2,-1)
Step-by-step explanation:
3x + 5y = -11
3x = -1 - 7y
-(-1 - 7y) + 5y = -11
y = -1
3x=-1-7x(-1)
x = 2
(x,y) = (2,-1)
-3x2+5x(-1) = -11
3x2+7x (-1) = -1
-11 = -11
-1 = -1
solution
x and y = (2,-1)
