Find the mean of the data set 31,31,22,28,23?

Lina20 [59]

The mean is 27
How you do this is you add all the numbers together even the ones that are duplicated like in this case 31. Now add em all up which equals 135. Now you take the number that they equal up to and divide by how many numbers are in the set of data in this case it is 5. After dividing you get 27.
I hope this helps!

Julli [10]

Answer:

-1.2

$10.9p+3.9=-9.18$

$10.9p=-13.08$

Divide -13.08 by 10.9

$-13.08/10.9=-1.2$

Ede4ka [16]

Answer:

effective annual rate is 6.16 %

Step-by-step explanation:

given data

rate = 6 % = 0.06

time 5 year = 10 semi annually

to find out

effective annual rate

solution

we know formula for annual effective rate of interest is

rate of interest = $(1+ r/n)^{n}$ -1

put here all value

rate of interest = $(1+ 0.06/10)^{10}$ -1

rate of interest = $(1+ 0.06/10)^{10}$ -1

rate of interest = 0.061646

so effective annual rate is 6.16 %
