Mean is a problem of addition and division.
It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
We can consider the following set of numbers.
= 1, 2, 3, 4, 5
The mean of 1, 2, 3, 4, 5.
= (1 + 2 + 3 + 4 + 5) / 5
= 15/5
= 3
We see that,
While calculating the mean we add all the given values and divide by the number of values added.
Thus,
Mean is a problem of addition and division.

than 1.
Answer:
Because of the range of the sine function.
Step-by-step explanation:
The reason why the value of the sine ratio for an acute angle
of a right triangle must always be a positive value less
than 1 has to do with the the range of the sine function.
The range of the sine function is
But in the first quadrant all y-values are positive and acute angles are less than 90°.
Therefore the range will now be 0≤y<1 for acute angles.
Sample Response: The sine ratio is the length of the side opposite a given acute angle divided by the length of the hypotenuse. Because the hypotenuse is the side opposite the largest angle, the 90° angle, it has to be the longest side. Thus, the ratio will have a denominator that is larger than the numerator, and the ratio will be less than 1.
