At higher elevations water boils at lower temperatures. the temperature at which water boils is called the boiling point of water. at sea level the boiling point of water is 100oc, while at 2 kilometers of elevation (about 6550 feet) the boiling point of water is 94oc. the function that gives the boiling point of water in oc, b
b
, at an elevation of x
x
kilometers is b(x)=100−3.5x
b(x)=100-3.5x
.

determine the elevations at which the boiling point of water is between 84 oc and 96 oc. give your answer accurate to 1 decimal place.

the 3rd on is correct

step-by-step explanation:

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
