Bruce added some chlorine to the water in a pool. the chlorine evaporated at a fixed rate every week. the table below shows the amount of chlorine f(n), in ounces, that was left in the pool after n weeks:
n f(n)
1 54
2 27
3 13.5
4 6.75
which function best shows the relationship between n and f(n)?

f (n) = 54 (0.5)^(n-1)   is your answer !

step-by-step explanation:

to solve this problem, let us first remember that the formula for this rate is:

rate = f (n) = a (r)^(n-1)

where as,

a = the 1st term

r = fractional rate of evaporation

n = number of terms

now let us calculate for the fraction rate of evaporation, r.

since it is stated that the evaporation is happening at a fixed rate, therefore

we can use any two given f (n) values to find for r. in this case, let us use

when n=1 and 2.

r = 27 / 54

r = 0.5

the first term in the series is when n = 1 and that is:

a = 54

therefore substituting all known values to the equation:

f (n) = 54 (0.5)^(n-1)     - this will be your final answer !

dont think so

step-by-step explanation:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
