Hello,
Answer B
(x-(-5))²+(y-2)²=5²
(x+5)²+(y-2)²=25
Answer:
D: 
Step-by-step explanation:
Option A equates to 
Option B equates to 
Option C equates to 
Option D equates to
which cannot be defined as division by 0 is impossible
' 40% ' means 0.4 .
You said that 60 = 0.4 x Full
Divide each side by 0.4 : 60 / 0.4 = 1 x Full
Full = 150 .
Let b = blue marbles
y = yellow marbles
Sum = b+y
The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * <span>y / (b+y-1) = 0.37</span>
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%
