Answer:
4250 km
Step-by-step explanation:
If we convert 25/6 into a mixed fraction, we get 4 1/6. Since we already know the plane goes for four hours already, we can multiply 1020 km x 4. That would give us 4080. Now that we converted the equation into a mixed fraction, we also know that the plane goes for an extra 1/6 hour. We divide 1020/6 because it is a sixth of an hour and the plane can travel 1020 in an hour. We get 170 km for 1/6 of an hour.
4080km + 170km= 4250 km
Answer:
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421
Step-by-step explanation:
We assume the following table:
No Hou. smokes >=1 hou. smokes Total
______________________________________________________
Student indicates he Cell 1 Cell 2 Cell 3
or she has asthma
_______________________________________________________
Student indicates he
or she does not have Cell 4 Cell5 Cell 6
asthma
_______________________________________________________
Total Cell 7 Cell8 1000
We are assuming a grand total of 1000 people for this case
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421
Answer I think that it is one
Step-by-step explanation:
Although you walked 4 km, the displacement is zero because you ended up back where you originally started.
Answer:
11505 bacteria
Step-by-step explanation:
Given :
The bacteria in a certain culture triples every 7.7 hours. The culture has 6,500 bacteria at the start .
As per the exponential growth , we have
Here ,
is starting number of bacteria
R is rate at which number of bacteria increases
T is time elapsed
P is one period of rate
On putting these values in formula , we get
So, the culture will contain 11505 bacteria after four hours .
