To conduct an experiment, the room temp in a lab needs to be as close as possible to -2 degrees Celsius. Any variation from its target temp, whether warmer or cooler, is considered an error that could affect the experiment. Function v gives absolute temp error as a function of the room temp in degrees Celsius, x.

Select all the statements that are true about the function and the situation.

A. When the room temp is 0 degrees Celsius, v(0) has a value of 2

B. When the room temp is -3 degrees Celsius, the absolute temp error, v(-3) is -1

C. When the room temp is 3 degrees Celsius, v(3) is 5

D. The equation v(x) = | x + 2 | gives the absolute temp error when the room is degrees Celsius

E. When v(x) = 0.5, the room temp could be -1.5, or -2.5 degrees Celsius

F. The equation v(x) = | x + 2 | gives us the absolute temp error when the room temp is x degrees Celsius

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

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

$25 becasue a 10 increase would make it from 80 to 50
