1.875
Step-by-step explanation:
I think it’s (3,4) the third answer
Answer:
quadrant 2
Step-by-step explanation:
because its a + and - and only quadrant 2 can have it
We are given equations as

Firstly, we will write in slope intercept form of line
y=mx+b

Subtract both sides by 4x


now, we can divide both sides by a

we can find slope
so, we get

we are given second equation as

Firstly, we will write in slope intercept form of line
y=mx+b
divide both sides by a

we can find slope

we are given both lines are perpendicular
so, the multiplication of their slopes must be -1

we can plug values

now, we can solve for a

Multiply both sides by a


now, we can solve for a
we get
...............Answer
<span>In a jar of ten beads; since 3 are blue; probability of picking a blue ball, B, = p(b) = 3/10. And P (of not picking a blue ball) ; p(b') = 7/10.
Since it occurs with replacement, probabilities doesn't change
Probaility of picking k blue balls from on n attempts is given by P_n(k)
P_n(k) = (n, k) p^(k) q^(n -k) where p and q are b and b' respectively.
P_5(2) = (5 , 2) (0.3)^(2) (0.7)^(5 - 2)
P_5(2) = 5C2 (0.3)^(2) (0.7)^(3) = 0.3087</span>
