Answer:
The answer is 20
Step-by-step explanation:
When you take the height of the triangle (which is 4) you take that and divide it by 2 or multiply by 1/2 which gets you 2. Then you take the two bases of the trapizoid and add them up to get 10 and then you multiply the two from earlier by 10 to get 20.
Answer:

Step-by-step explanation:
<u><em>the mean in period</em></u> 1 :
(2.3+2.1+2.2+2.2+2.2+2.1+2.4+2.5+2.2+2.0+1.9+1.9+2.1+2.2+2.3)÷15=21.733...
<u><em>the mean in period</em></u> 2 :
(2.3+2.1+3.3+1.5+3.6+1.6+3.0+1.1+4.7+2.1+2.4+1.9+2.8+0.5+2.3)÷15=23.466...
Since 23.466 > 21.733 then “The mean in period 2 is higher than the mean in period 1”.
