Answer:
C. c(t) = 5 + 15t
Step-by-step explanation:
Well because the initial fee is $5, the answer must have the value of 5 without a variable next to it because this is the y-intercept.
(Only the slope will have the t next to it.)
Because $15 is charged <u>EACH HOUR</u> this would be the slope because there is a constant increase
Therefore c(t) = 5 + 15t
Answer:
First piece: 6,5
Second piece: 19,5
Step-by-step explanation:
"Cut 25 into 2 pieces" = "divide 25 by 2"
So, we must divide 25 into 2 unequal pieces, where the first piece is 13 less than the second one (x).
What we could do is simply get a random number, preferably close to 12,5 (the half of 25), and add a number to the first piece and decrease a number from the second one; these two numbers, though, must add to 13 (or any other number you choose) together.
25 / 2 = 12,5
12,5 - 6 = 6,5 (this would be x - 13)
12,5 + 7 = 19,5 (this would be x)
19,5 - 6,5 = 13 or x - (x - 13) = 13 (there is indeed a difference of 13).

I never been good at that either
C. would be the correct device to use in trials.
But the actual probability is:
(1-1/4)^5
243/1024
(about 23.73% chance none of the five chose vanilla)
