Answer:

1000xm

Step-by-step explanation:

1 meter = 3.2808 feet, hence. 9.8424 x 10^8 feet in 1 second. 1 foot in x seconds. hence it takes 1 / (9.8424 x 10^8) = 0.10168 x 10^(-8) seconds. ➡️1km = 1000xm⬅️

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.

The solution set for -p^2 − 11p = 0 is
mihalych1998 [28]
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}

A company makes greeting cards and their research shows that that price and demand are related linearly: p = mx + b. They know t
Andrew [12]

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

See graph attached.
