The table represents the change in the boiling point of water at different altitudes.
(in thousands of feet) Boiling Point of Water
(sea level) 0 212

so how do I apply that to this problem
well pick out 2 consecutive readings
- say 4 , 204.8 and 4.5, 203.9
slope will be (203.9 - 204.8) / (4.5 - 2.0)
so would it be
For every increase of 1,000 feet in altitude, the boiling point of water decreases by 1.8 degrees Fahrenheit.
yes - but second thoughts that might not be a very good estimate
better to do the calculation over a bigger range
best would be (203.9 - 211.1) / (4.5 - 0.5)
- that still gives -1.8 lol
ok well the answer choices are
A.For every increase of 1,000 feet in altitude, the boiling point of water increases by 1.8 degrees Fahrenheit.
B.For every increase of 1,000 feet in altitude, the boiling point of water decreases by 1.8 degrees Fahrenheit.
C.For every decrease of 1,000 feet in altitude, the boiling point of water decreases by 1.8 degrees Fahrenheit.
D.For every increase of 1,800 feet in altitude, the boiling point of water decreases by 1 degree Fahrenheit.
E.For every decrease of 1,800 feet in altitude, the boiling point of water decreases by 1 degree Fahrenheit.
and I thought that that was the best answer
yea that's B right
ok thank u :D
do you know which are the dependent and indep[endent variables?
Altitude is the independent and Fahrenheit is the dependent
