To fine the mean for a first add up all the players heights then divide by the number of players.
Mean=(198+199+200+201+202)÷5
=1000÷5
=200
The answer to a is 200
For question be were gonna say for now that the height of our new player is represented by x. So we know that together there is 6 players and we know our answer so it should look something like this
201= (199+198+199+200+201+202+x) ÷ 6
201=1000+x ÷ 6
Then Im going to multiply 201 by 6 to get rid of the 6 on the other side.
1206=1000+x
Then I’m going to subtract 1000 from both sides to get x by itself
206=x
So the new players height is 206 .

I hope this is right!
Answer:
x=44
Step-by-step explanation:
By the exterior angle theorem, we know that
x+4+82=3x-2
simplify
x+86=3x-2
subtract x from both sides
86=2x-2
add 2 to both sides
88=2x
divide 2 from both sides
44=x
Answer:
1440
Step-by-step explanation:
The sum of the exterior angles of a regular polygon of 10 sides = 360 deg. The sum of the interior angles of a regular polygon of 10 sides = 10*[180 - (360/10)] = 10(180–36) = 10*144 = 1440 deg.
