Answer:
look at explanation
Step-by-step explanation:
To solve all of these questions you just need to scale. While scaling you can divide or multiply.
1. (divide by 4 to get unit rate)
unit rate =
2. If it takes one hour to travel 40 miles, then we don't have to scale or anything. We know , the answer is...
"It'll only take one hour to travel 40 miles. This is correct because the unit rate is . "
3. Knowing that the constant speed of the plane is , we can scale then add half of the unit rate to get our answer.
x 3 = 800 x 3 = 2400
then add half of unit rate which is = 400
so, our answer is
4. <--- ( divided by 2) ( multiplied x 2.5) --->
To get an easier way to find the answer, if possible you can scale back farther than the 1 hour mark.
Elmer would take 2 and a half hours to ride 15 km.
5. The boys speed is . All we need to do is divide by 2. = 4
There will be 45,600 bacteria present after 19 hours

Answer:
Step-by-step explanation:
there are 40320 possible arrangements. that would be 8!
the probability of picking the correct order randomly would be 1 / 40320 = .0000248015873.
in order words, the probability of picking the correct order on a random basis, such as picking the names out of a hat, is not very good.
<u>for example:
</u>
suppose there were only 3 reamining candidate.
3! = 3*2 = 6
there would be 6 possible arrangements. if the candidates were abc, then the 6 possible arrangements would be:
abc
abc
bac
bca
cab
cba
for 4 candidates, multiply 6 * 4 = 24
then 5 * 24 = 120
then 6*120 = 720
then 7*720 = 5040
then 8 * 5040 = 40320
1 / 6 is manageable.
1 / 24 less.
1 / 8 becomes pretty impossible.
