Answer:
im in online school
Step-by-step explanation:
Answer:
18
It’s literally 72 divided by 4 which equals 18
You would need exactly 9 correct questions to get a 50%.
We can find this by multiplying the total number of questions by the percentage we are looking for.
18*50% = 9
Formula for growth:
y = initial • (percent growth + 1)^time/frequency of growth
So, since initial population is 382
Percent growth is 0.007
The time is 30 years
And it goes it by .07% every 1 year,
y = 382 • (1.007)^30/1
y= 470.9203732 people
Since we can’t have 0.9 of a person, the population after 30 years will be 470 people.
