B.
The Probability of choosing a girl is 17/30.
The probability of choosing an A student is 5/30
<span>The P(girl) + the P(A student) = 17/30 + 5/30 = 22/30 = 11/15.</span>
Answer:
(-9)+(-9)+(-9)
Step-by-step explanation:
(-9)+((-9)+(-9)) = -27
Answer:0.06
Step-by-step explanation:
Step-by-step explanation:
Let us move everything to the one side with y by itself to make it easier. the first equation we don't have to change. y=2x+12 and the second equation becomes -y=-2x-12 and we can divide both sides by negative to get rid of the negative on y so it becomes y=2x+12. So they are the same thing.
Answer:
k = 2a = 10
Step-by-step explanation:
If
x² / 25 − y² / 56 = 1
we know that
a² = 25 ⇒ a = 5
b² = 256 ⇒ b = √256
The equation of the hyperbola defined by |FP − PG| = k can be written as follows:
|FP − PG| = 2*a
then
2*a = 2*5 = 10
