Answer:
He isn't correct. He spent 25% more time this week than the previous one.
Step-by-step explanation:
We will make proportion.
first week 20 hours is 100%
second week 25 hours is x%
20 : 25 = 100 : x
When we multiply external and internal members we get:
20x =25 · 100 => x = 2500/20 = 125%
We conclude the following:
Evan spent 125% of the time in hours compared to the last week or Evan spent 25% more time this week than the previous one.
God with you!!!
Answer:

We can divide both sides by 20 and we got:

Now we can appply natural log on both sides and we got:

Now we can divide both sides of the equation by 10 and we got:

So then the aproximate value of k is 0.30986 and rounded would be 0.31
Step-by-step explanation:
We have the following two expression:


We know that the two populations were equal 10 years after the start of the study, so then we can create the following equation:

We can divide both sides by 20 and we got:

Now we can appply natural log on both sides and we got:

Now we can divide both sides of the equation by 10 and we got:

So then the aproximate value of k is 0.30986 and rounded would be 0.31
I believe the answer is x=0
