Daejoy and damian collect fossils. before they went on a fossil-hunting trip, daejoy had 25 fossils in her collection, and damian had 16 fossils in his collection. on a 10-day fossil-hunting trip, they each collected 2 new fossils each day.
a. make a table showing how many fossils each person had in their collection at the end of each day.
b. if this pattern of fossil finding continues, how many fossils does damian have when daejoy has f fossils?
c. if this pattern of fossil finding continues, how many fossils does damian have when daejoy has 55 fossils?

a) 45, 36 respectively, b) F-9, c) 46

Step-by-step explanation:

Since we have given that

Number of fossils Daejoy had in her collection = 25

Number of fossils Damian had in her collection = 16

On a 10 day fossil hunting trip, number of new fossils on each day = 2

a) So, Total number of fossils Daejoy had after 10 days is given by

Total number of fossils Damian had after 10 days is given by

b) If Daejoy had F fossils, then we need to find the number of fossils Damian had.

Since difference between Daejoy and Damian is

So, Number of fossils Damian had is F-9.

c. If this pattern of fossil finding continues, how many fossils does Damian have when Daejoy has 55 fossils?

Number of fossils Daejoy had = 55

So,  the number of fossils Damian had

Hence, a) 45, 36 respectively, b) F-9, c) 46

answer:

a=9

step-by-step explanation: lmk if you need a 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
