The following nine values represent race finish times in hours for a randomly selected group ofparticipants in an extreme 10k race (a 10k race with obstacles). which of the following is closest tothe mean of the following data set? 1.0, 1.2, 1.2, 1.3, 1.4, 1.5, 1.5, 1.7, 2.1

The mean for the given sample of finish race time is 1.43 hours.

Step-by-step explanation:

We are given the following in the data set:

1.0, 1.2, 1.2, 1.3, 1.4, 1.5, 1.5, 1.7, 2.1

Formula:

The mean for the given sample of finish race time is 1.43 hours.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
