Answer:
C) The mean is about 100.
Step-by-step explanation:
We see that the best fit line (out of the options listed) would be y=100. The mean can also be algebraically calculated with the following equation:
Let be the mean (average) of the values:
, which is closest to answer choice C) The mean is about 100.
Given:
The base of the triangle = 8.6 yd
The height of the triangle = 10.9 yd
To find the area of the triangle.
Formula
The area of a triangle with b as base and h as height is
Now,
Taking, b= 8.6 and h = 10.9 we get,
sq yd
or, sq yd
Hence,
The area of the given triangle is 46.87 sq yd.
