The answer is mean 15 median 15.5 mode 16
4+3+2=9
216/9=24
(A)- 4 x 24= £96
Hope this helps!☺
Because the boat travels the distance twice as fast when going 3 three miles/hour faster the original speed must be 3 miles/hour. so the distance upstream would be 21 miles/hour.
We know that the sum of all the exterior angles will add up to 360°.
We can solve this using an expression:
360/n
n = the number of sides (in the problem, we are given 19 sides)
Solve with the given value:
360/19
18.947368
Round to the nearest tenth:
18.947368 → 18.9
Therefore, the answer is 18.9
Best of Luck!
