Whats a+2 over 2=-1 ??

tia_tia [17]

Not sure what exactly you meant, so i solved for both possibilities...

Answer: a=-2

assuming you mean a+2/2=-1.....

a+2/2=-1
simplify..
a+1=-1
subtract 1 from both sides
a=-2
____________________

Answer: a=-4

assuming you mean (a+2)/2=-1...

(a+2)/2=-1
simplify...
a/2+2/2=-1
simplify
a/2+1=-1
subtract 1 from both sides
a/2=-2
multiply both sides by 2
a=-4

Looking at the means of these samples, which value is most likely to be the mean of the population from which the samples were t

eduard

Answer:

We are given the below data:

Sample Number Sample Mean

1 11.8

2 12.5

3 15.1

4 14.3

5 13.0

6 12.9

7 10.2

8 11.5

9 12.9

10 15.4

Now the most likely mean of the population can be found by finding the mean of given sample means. It is given below:

$Mean = \frac{11.8+12.5+15.1+14.3+13.0+12.9+10.2+11.5+12.9+15.4}{10}$

$=12.96$

Therefore, the most likely mean of the population from which the samples were taken is 12.96
