The average score is 87.17647058823529 or 87.17 or 87.2, because you add all of them together then you divide it by how many scores there are.

densk [106]

Answer:

4:7

Edit: I just saw the multiple choice options, in this case the right answer is:

<h2>8:14</h2>

but they're both equal

Step-by-step explanation:

The ratio you are looking for is

freestyle laps : (freestyle + butterfly) laps

so:

8 : (6+8)

8:14

Someone answer this please, I’ll give you brainliest and your getting a lot of points.
ANTONII [103]

Answer:

Step-by-step explanation:

Recursive formula

tn = t_n-1 / 4

t2 = t1 / 4

t2 = 10240

t1 = 10240 / 4 = 2560

Explicit formula

tn = 10240 / 4^(n-1)

t4 = 10240 / 4^(4 - 1)

t4 = 10240 / 4^3

t4 = 10240 / 64

t4 = 160

t8 = 10240 / 4^7

t8 = 0,625
