Answer:
206
Step-by-step explanation:
70% of 294
70/100 × 294/1
205.8
round it off to 206
Step-by-step explanation:
Part C: Of the following choices, which equation is the best fit line for the data
As we can see from the data, the population size are decreased year by year, so the slope of the line of best fit must be a negative number.
So we have: C and D left.
Let x = 0, year 2005, the population size is 296 around 320, hence, we choose D.
D f(x) = -34x + 320
Part D: What is the predicted population size for the year 2010? How does that compare to the real data? Round to the nearest million.
year 2010, x =5 so let substitute x =5 into f(x) = -34x + 320
<=> f(x) = -34*5 + 320
= 150 mil
The result is smaller than the real data, (201-150 = 51 mil)
Part E: In what year is the population predicted to go extinct
the population predicted to go extinct when f(x)= 0
<=> -34x + 320 = 0
<=> x ≈ 9.4
So after 10 years, the the population predicted to go extinct
Answer:
- $17,500 at 14%
- $16,000 at 12%
Step-by-step explanation:
Let x represent the amount loaned at 14%. Then the total interest earned is ...
0.14x +0.12(33,500 -x) = 4,370
0.02x = 350 . . . . . . . . . . subtract 4020 and simplify
x = 17500 . . . . . . . . . divide by 0.02
The amount loaned at 12% is $33,500 -17,500 = $16,000.
$17,500 was loaned at 14%
$16,000 was loaned at 12%
Answer:
-18
Step-by-step explanation:
Google tbh
Answer:
Crew: 32
Marty: 48
Blakely: 24
Step-by-step explanation:
I mainly just used guess and check. Crew is 32 years old. So, let's find Marty's age.
32 × 1. 5 = 48
Marty is 48. Now, let's find Blakely's age.
32 × 0.75 = 24
Add all the ages together.
32 + 48 + 24 = 104
Hope that helps.
