For this case we have the following linear equation:
d = 15.7p + 2.0
Where,
p: number of people
d: total bill
We note that the slope of the equation is:
m = 15.7 $ / person
Therefore, the amount of the bill increases if the number of people grows.
Answer:
b) The model predicts that for each additional person at a table, the total bill increases by $ 15.70.
First note that 10 2/3 feet equate 127.2 inches.
Denote by x the distance we are looking for.
We have the following equation:
![x+25+x+25+x=127.2](https://tex.z-dn.net/?f=x%2B25%2Bx%2B25%2Bx%3D127.2)
Solving the above equation for x we get:
The distance is 25.7 inches.
Answer:
no
Step-by-step explanation:
Let f represent the fraction of C-14 remaining as a function of the time t in years. Since the half-life of C-14 is about 5570 years, we have ...
f = (1/2)^(t/5570)
Taking the log and solving for t, we get ...
log(f) = (t/5570)log(1/2)
5570·log(f)/log(1/2) = t
Filling in the given value for f, the value of t we get is ...
5570·log(0.65)/log(0.5) = t ≈ 3462
It appears the estimate of 4000 years is a bit high.
