Answer:
P (A and B)=8/9
Events A and B are not dependent.
Step-by-step explanation:
Probability of A AND B means the the probability (favorable outcomes divided by total) of choosing someone who has/did BOTH A and B (not neither or only one of them). 16 did both, so the probability is 16/18 /2/2 = 8/9.
The events are independent (not dependent) because choosing A does not affect choosing B.
There are two solutions. If you factor a -p out of the equation, you can easily see this. (-p)(p + 11) = 0. The values of p that make this true are 0 and -11.
{0, -11}
Answer:
p = -0.05x+22
Step-by-step explanation:
The general linear equation of price-demand is
(1) <em>p = mx + b
</em>
<em>
</em>
where x is the demand of cards in units when they are sold at x dollars.
If for every additional card they wish to sell they need to drop the price by $0.05, then
(2) p-0.05 = m(x+1)+b
To sell 360 cards they need to set the price at $4, so
(3) 4 = m.360+b
We need to find m and b.
Operating on eq. (2) we have
p-0.05 = mx+m+b
mx+b-0.05 = mx+m+b
m = -0.05
Replacing this value in (3)
4 = (-0.05)360 +b
4 = -18+b
b = 22
So, the linear equation relating price p to demand x is
p = -0.05x+22
