The following is a list of 11 measurements: -2,82,87,-1,-51,-2,53,87,-20,32,35

Suppose that these 11 measurements are respectively labeled. x1,x2¡¦¡¦¡¦¡¦¡¦x11.(Thus,-2 is labeled x1,82 is labeled x2 and so on.)
find ¢²_(i=1)^11¢Æx1/49

Round your answer to at least two decimal places.

I get

add -2,82,87,-1,-51,-2,53,87,-20,32,35=300

300/49=6.12244

Round two decimals = .061244 or 61.22? I don't know which way I should go.

Maybe if you would repost (again) and this time proofread for nonsense symbols that only you know what they mean.

What is
"x1,x2¡¦¡¦¡¦¡¦¡¦x11.(Thus,-2 is labeled x1,82 is labeled x2 and so on.)
find ¢²_(i=1)^11¢Æx1/49"

Your question is not clear.

What are you supposed to do with this list of numbers?

To find the value of (x1/49) for the given sequence of measurements, we need to first calculate the value of x1 and then divide it by 49.

The formula (x1/49) asks for the value of the first measurement, x1, divided by 49.

Given that the first measurement is -2, we can substitute it into the formula as follows:

(-2)/49

Now, we can divide -2 by 49 using a calculator or perform the division manually to get the result.

Using a calculator, the value of (-2)/49 is approximately -0.04082.

Therefore, the value of (x1/49) for the given sequence of measurements is approximately -0.04082.
