Orthocenter. The orthocenter is the place where the altitudes intersect in a triangle. The altitude of a triangle is a line that connects to a vertex and is perpendicular to the base opposite to that vertex.
Note that 72-68 = 4, and that 4 is 2 std. dev. from the mean.
68 would be 2 std. dev. below the mean. Alternatively, we could say that the z-score corresponding to a raw score of 68 is -2.
Using either a calculator with built-in stat. functions, or a table of z-scores, we can find the area under the curve to the left of 68. That area is 0.023.
We could also use the Empirical Rule here. That Rule states that 95% of data whose distribution is normal lie within 2 std. dev. of the mean.
This means that (95%/2), or 47.5% of the data lies between 68 and the mean. To the left of the mean is 0.5 of the total area under the curve. So the percentage of males whose heights are no more than 68 inches is 50% less 45.5%, or 2.5% (answer, just slightly different from the previous result).
Answer:
52 1/2
Step-by-step explanation:
105 divided by 2 is 52.5 because it's in halves or in 1/2 you would just put 1/2 next to the 52 I guess.
