Answer:

The median is 58

<h2>Step-by-step explanation:</h2>

To calculate the median, you must put the series of numbers in chronological order (smallest to biggest), then find the number in the middle. If there are two numbers, add them up and divide by two.

<h2>For this question:</h2>

<u>Step one; put them in order</u>

56 65 62 53 68 58 65 52 56

52 53 56 56 58 62 65 65 68

<u>Step two; find the middle</u>

52 53 56 56 58 62 65 65 68        

                     58      

<u>The answer</u>

Because there is an impair number, there is a number in the middle.

<em>58 is the median retirement age.</em>

Find the angle between 450 and 630 that has the same sine as -60
Maksim231197 [3]

Answer:

The angle is of 600º.

Step-by-step explanation:

Angle of -60:

An anle of -60 is the same as an angle of -60 + 360 = 300º, which is in the fourth quadrant. In the fourth quadrant, just like in the third, the sine is negative.

Equivalent of an angle of 300º in the third quadrant:

The equivalent of an angle of 300º in the third quadrant(between 180 and 270) is given by: 270 - (300 - 270) = 270 - 30 = 240º. That is, they have the same sine.

Angle between 450 and 630:

This is on the second lap of the trigonometric circle, that is, we take the original measures and add 360º(length of a lap). So

240 + 360 = 600º

The angle is of 600º.
