BaLLatris [955]

Answer:

20,158 cases

Step-by-step explanation:

Let t=0 represent year 2010.

We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.

Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.

We can represent this information in an exponential decay function as:

F(t)=102,390(1-0.15)^t

F(t)=102,390(0.85)^t

To find number of cases in 2020, we will substitute t=10 in our decay function as:

F(10)=102,390(0.85)^{10}

F(10)=102,390(0.1968744043407227)

F(10)=20,157.970260446597\approx 20,158

Therefore, 20,158 cases  will be reported in 2020.

Stacy is having a party. She puts 6 six-packs of diet soda in a cooler for her guests. At the end of theparty, she finds that 8
andreev551 [17]
So since each pack has 6 packs we need to multiple. 6x8= 48.

There were 48 diet sodas in the cooler. 40 were drank. The fraction would be 40/48 were drank or 8/48 cans were not drunk.

For the lowest term, it would be 1/6 for 8/48 and 5/24 for 40/48.

Good luck with your studies! <3
