The range of scores in each interval of a grouped frequency distribution is called the

1 answer:

3 0

The answer is class intervals. A big set of data are grouped into different classes to get a hint of the distribution, and the range of such class of data is known as the Class Interval. In other words, these are range of scores in a group frequency distribution. Class intervals are commonly equal in width and are mutually exclusive. The middle of an interval is called a class mark and the ends of a class interval are called class limits. To calculate the class interval, divide the range by the number of classes.

An obtuse triangle is formed if there is an angle that has a measure of more than 90 degrees. You can determine if an obtuse angle is formed by two sides of a triangle if it meet this condition:

Let a and b be two sides of a triangle and c is the longest side:
$a^{2} + b^{2} \ \textless \ c^{2}$

So taking your given:

$10^{2} + 15 ^{2}$ < $c^{2}$
100 + 225 < $c^{2}$
325 < $c^{2}$

To get the smallest possible number, just get the square root of both sides:

$\sqrt{325}$ < $\sqrt{c^{2} }$
18.03 < c

So your smallest possible whole number is 19

Solve sin x + 2 sin x cos X = for 0°

solniwko [45]

Answer:

Step-by-step explanation:

hello :

sin x + 2 sin x cosx = 0 equivalent to : sinx(1+2cosx) =0

sinx=0 means : general solution is : x= kπ....k in Z

1+2cosx=0 means : cosx= -1/2 general solution is : x= ±π/6+kπ...k in Z
