To find the mode of the given data first we have to arrange it in a increasing order then find out mean and median of the given data
0.7,1.7,3,3.2,4.1,5.9,6.6,8.9 is in increasing order
For finding the median we need to take the average of 4th and 5th terms because we have the no of terms in the sequence is even not odd so we need to take the average the 4th term=3.2 and the 5th term =4.1
so average =(3.2+4.1)/2=3.65
so the median is equal to 3.65
For mean we have to take the average of the data
so mean= sum of all data /no of data
mean =(0.7+1.7+3+3.2+4.1+5.9+6.6+8.9)/8=4.26
so by using the formula we can get mode
<em>Mode=3×Median-2×Mean</em>
Mode=3×3.65-2×4.26=2.43
∴The value of Mode is given as 2.43

Answer:

150m^2

Step-by-step explanation:

Given data

a=8m

b=17m

h=12m

We know that the expression for the area of a trapezoid is given as

Area= (a+b/2)*h

substitute

Area= (8+17/2)*12

Area= 25/2 *12

Area= 12.5*12

Area= 150 m^2

Hence the area is 150m^2
