A group of students was asked, "How many hours did you watch television last week?" Here are their responses.
6, 16, 5, 16, 13, 12, 20
Find the mean number of hours for these students.
If necessary, round your answer to the nearest tenth.

12.6

Step-by-step explanation:

6+16+5+16+13+12+20

=22+21+25+20

=43+45

=88

There are 7 responses.

88/7=12.6  (rounded to the nearest tenth.)

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
