The ratio of the angles of a triangle is 5: 2/3: 1 Then the measure of all three angles are 135, 18, 27 respectively.
<u>Solution:</u>
Given that, the ratio of the angles of a triangle is
We have to find what are the measures of all three angles.
Let us suppose, "x" is the highest common factor of three angles.
Then, the three angles will be
Now, we know that, sum of angles of a triangle equals to 180
So, the three angles will be,
Hence, the angles of the triangle are 135, 18, 27 respectively.
In statistics, when you gather data points for the same test, you construct a distribution graph. For example, you make a statistics based on the score of a class for a 145-item test. You graph it based on frequency such as, 10 students got 50 points and so and so forth. When that test have a few outliers and have more or less the same score, you form a normal distribution graph. It is more commonly known as the Gaussian Bell Curve. An example would be shown in the picture.
A normal distribution curve is symmetric about the mean. As a result, the area under the curve on the left side of the mean would be equal to the area under the curve on the right side of the mean. So, each would constitute 50%.
