815 gal/h convert to qt/sec

Answers

Answer:

0.905 qts/s

Step-by-step explanation:

First we have to know the equivalent of each unit

1 gal is equal to 4 qt

1 hour is equal to 3600 sec

Now we have to order each of the units $815 (gal)/(h)$ ⇒ $(4 qt)/(1 gal) *(1 h)/(3600 sec)$

$(815 gal*4 qt)/(1 gal) =3260$ in this step the gal are eliminated

Now we have to convert the seconds

$(3260 *1 hour)/(hour*32600 sec) =0.905$

Now we convert the hour to seconds

so the answer is 0.905qt/sec

(815*4÷60) qt/ (60÷60) sec

If you have a 1 in a thousand chance of winning $400, but 999 out of a thousand times you win nothing, what is your expected payoff

Answers

Answer:$0.4

Step-by-step explanation:

Let $P_(w)$ be the probability of winning.

Let $P_(l)$ be the probability of loosing.

Given that we win once in thousand times.

So, $P_(w)=(1)/(1000)$

Since $P_(w)+P_(l)=1$

$P_(l)=1-P_(w)=1-(1)/(1000)=(999)/(1000)$

Since we win noting if we loose,

expected payoff is product of probability of winning and the prize.

Let $pr$ be the prize.

Given, $pr=400$

Expected payoff is $pr* P_(w)=400* (1)/(1000) =0.4$

So,$ $0.4$ is the expected payoff each time.

Answer:

$0.4
