Add all the numbers together, then divide by how much numbers were in the set.

5 + -11 + 7 + 12 + -1 = 12

There are SIX numbers in this set

12/6 = 2

Answer: 2 is the mean

If you add all the numbers, you get 12. divide this number by the number of numbers there are in total and you get 12 divided by 6. So the mean is 2.

Find the lateral area of the prism. 4cm 3cm 6cm 5cm Lateral Area = [?]cm2

kolbaska11 [484]

Answer:

The lateral surface area of a prism is the sum of the surface areas of the sides of the prism.

Since the bases of the prism are triangles, there are three sides. The area of each lateral is the product of a side of the triangle times the height of the prism.

We can express this as Lateral Surface Area LSA = (s1xh) + (s2xh) + (s3+h), where "s1, s2, s3" are the lengths of the sides of the triangle and "h" is the height of the prism.

We can factor out "h" to get LSA = hx(s1+s2+s3) where the factor "s1+s2+s3" is the perimeter of the triangle.

Solving for "h", we get h = LSA / (s1+s2+s3)

For your specific problem, h = 300 / (4 + 5 + 6) = 300 / 15 = 20
