Answer:
Step-by-step explanation:
First thing is to remember the sin ratio. It is, by definition, the side opposite over the hypotenuse of the reference angle. In QIII the side opposite the angle is -8 which is one of the legs of a right triangle, and the hypotenuse, which is always positive, is 10. That means that if we are going to find the cosine of the angle, we need the other leg of the triangle. Using Pythagorean's Theorem, we find that
and
and
so
a = 6. But because we are QIII, that value is negative, because x is negative in QIII.
That leg happens to be the side adjacent to the angle. The cosine of the angle is the side adjacent over the hypotenuse. So now that we have the side adjacent as -6, we can say that the cosine of the angle is -6/10.

Step-by-step explanation:
The term "concurrent validity" refers to the relationship between step count with vo2 data.
<h3>Define the term concurrent validity?</h3>
- The degree of agreement between two measurements or assessments made at the same time is displayed by concurrent validity.
- It contrasts a brand-new test with one that has already undergone testing and been shown to be reliable.
You wish to evaluate a new survey that measures employee commitment's concurrent validity. In order to accomplish so, you may:
- Ask the same group of employees to respond to your new survey as well as an earlier (validated) survey. then contrast the outcomes.
- Obtain some staff responses to your new survey. The findings of a popular employee performance indicator, including a performance evaluation, should then be compared to the respondents' responses.
There is a connection between daily step count and fitness level (as collected with vo2 testing)
Thus, the term "concurrent validity" refers to the relationship between step count with vo2 data.
