Explanation:
<u>Pie Charts</u>
They are graphic representations of quantitative results from experimental or theoretical experiences. Instead of showing a table, it's usually preferred to show a graph where the viewer can easily understand the relative relations between the parameters under study.
The chart pie is a circular shape divided into sectors whose areas are proportional to the proportions between each parameter and the total. Since the whole sector of a circle has 360°, each sector will be a proportion or ratio of that angle.
The outcome shown in the table gives us these statistics:
Small Cell Carcinoma
: 15%
Non-Small Cell Carcinoma
: 85%
Each category has the following angles in the chart pie
Small Cell Carcinoma
: 15%*360°=54°
Non-Small Cell Carcinoma
: 85%*360°=306°
The first category is shown in blue and the second in green. Please check the image below.
Explanation:
The 15th Amendment to the U.S. Constitution granted African American men the right to vote by declaring that the "right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude." Although ratified on February 3, 1870, the promise of the 15th Amendment would not be fully realized for almost a century. Through the use of poll taxes, literacy tests and other means, Southern states were able to effectively disenfranchise African Americans. It would take the passage of the Voting Rights Act of 1965 before the majority of African Americans in the South were registered to vote.
Answer:
<em>The angle introduces an error on the mesure of the weight</em>
Explanation:
<u><em>Weight and Normal Forces</em></u>
When an object is resting on a horizontal surface, its weight is directed downwards and the normal force has the same magnitude and opposite direction, i.e. directed upwards. When some angle α exists between the surface and the horizontal plane, the scale keeps 'feeling' the Normal force, but it's not equal to the weight anymore, but to the perpendicular component of the weight to the surface where the scale is placed. It can be found that the component of the weight is m.g.cosα
If, for example
, the real measure is

That is, 98.5% of the correct weight. So it's important to measure weight on horizontal surfaces
