Answer:

p = 50

Step-by-step explanation:

If you subtract 300 from 500, you get 200.

Everybody knows that 4 x 5 is 20, so do 4 x 50 then you get 200.

so Amy has to sell at least 50 pairs of shoes.

AKA the answer is A. ;)

Answer:

9pr = 2q^2

Step-by-step explanation:

28.

px^2 + qx + r = 0

If one root is A then the other root is 2A

We have A + 2A = -q/p   and A*2A = r/p

So 3A = -q/p  so A = -q/3p and  A^2  = r/2p  so A = √ (r / 2p)

Equating  these 2 equations:-

-q/3p =  √(r / 2p)

q^2 / 9p^2 = r / 2p

9p^2r = 2pq^2

9pr = 2q^2   (answer)

One option in a roulette game is to bet $ 6
Eduardwww [97]

Answer:

<h2>We have 47% of chances to win those six bucks.</h2>

Step-by-step explanation:

In this problem we need to find the probabilty of winning thos $6.

According to the problem, we win $6 if we hit one red. We know that there are 18 red compartments, 18 black compartments and 2 neither red nor blakc, for a total of 38 compartments.

We need to use the standard probabilty definition which is the ratio between the number of events and the total number of outcomes. So,

P=\frac{18}{38} \approx 0.47

Which is equivalent to 47% of chances.

Therefore, we have 47% of chances to win those six bucks. (The Casino has the odds in their favor)
