Dave is taking a algebra ii test and comes across this question: you have two die that you will roll. you will sum up the face v

sammy [17]

He should guess about 34 times.

When you are rolling two dice there are 36 probabilities. In order to get an 8, there are 5 possibilities.

2 + 6, 3 + 5, 4 + 4, 5, + 3, 6 + 2

Therefore, the chances of an 8 are 5/36. Multiplying this by 250 gives us about 34.

The law of large numbers helps because it says the more rolls that take place, the more likely we are to get close to the expected value. With 250 rolls we should get pretty close.

A furnace delivers 8.0 × 104 btu per hour. how many kilocalories per hour is this?

vazorg [7]

For this case the first thing you should know is the following unit conversion.
1 BTU = 0.25 Kilocalories
We then have the following numerical value:
$8.0 * 10 ^ 4 \frac{BTU}{h}$
Applying the conversion of units we have:
$8.0 * 10 ^ 4 \frac{BTU}{h} * 0.25 \frac{Kcal}{BTU}$
Canceling units we have:
$20000 \frac{Kcal}{h}$
Answer:
This is 20000 kilocalories per hour
$20000 \frac{Kcal}{h}$
