The answer is 35 because 2^3 = 8 and 3^3 = 27 so 27 + 8 = 35
The area of any triangle is (1/2) x (length of the base) x (height) .
In this problem, we know the triangle's height,
but what is the length of the base ?
The base is the side that the triangle is sitting on. This particular triangle
is an equilateral one, and its perimeter is 60m. So each side must be 20m.
No matter which side the triangle is sitting on, the length of the base is 20m.
Area = (1/2) x (base) x (height)
Area = (1/2) x (20m) x (17.3m) = <em>173 m²</em>
Answer: A. The difference in the sample size of the two groups makes a conclusion impossible.
The statement in letter A is very true. It is impossible to come up with a credible conclusion knowing the fact that the sample size for the two groups is not the same. The sample size affects the rate of the mean systolic blood pressure on both groups.
