You see, that it's divided into triangles. Find the area of each triangle using the formula: the area of triangle is base*height*1/2. Then, add all the areas altogether.
39x98 is 3,822. do you need to know how I got that?
Answer:
x mean x-mean (x-mean)^2
4.45 8.74 -4.29 18.44
5.50 8.74 -3.24 10.52
5.50 8.74 -3.24 10.52
6.30 8.74 -2.44 5.97
7.80 8.74 -0.94 0.89
11.0 8.74 2.26 5.09
12.2 8.74 3.46 11.95
17.2 8.74 8.46 71.51
mean = average / (n-1) = 69.95 / (8-1) = 8.74
Ok after you do the above table
Add up the last column that will yield: 134.89
Sample variance = 134.99/(n-1) = 134.99/7 = 19.27
Standard deviation is square root of sample variance sqrt(19.27) = 4.39
Step-by-step explanation:
Answer:
-16755
Step-by-step explanation:
3(15 - 5600)
multiply 15 and 5600 by 3
45 - 16800
subtract 45 by 16800
-16755
