Answer:

x = sqrt(17)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2

Let the unknown side be x

8^2 + x^2 = 9^2

64 + x^2 = 81

Subtract 64 from each side

x^2 = 81-64

x^2 =17

Taking the square root of each side

x = sqrt(17)

Answer:

x = √17

Step-by-step explanation:

Your question have a right triangle.

So, we could use the Pythagorean Theorem.

Pythagorean Theorem is a² + b² = c².

So, 8² + n² = 9².

8² is 64, and 9² is 81.

So, 'n' is 81 - 64.

Let's see... 81 - 64 is 17.

So, It is √17.

Because when you use the Pythagorean Theorem, it is 8² + (√17)² = 9².

Otherwise, 64 +  (√17)² = 81.

And, √17 is 4.12 when rounding to a hundredth.

Hope it helps!

Bye!

the number of steps per day is said to be related to fitness level (as measured with vo2 testing). which type of validity is des
taurus [48]

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:

  1. Ask the same group of employees to respond to your new survey as well as an earlier (validated) survey. then contrast the outcomes.
  2. 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.

To know more about the concurrent validity, here

I need help with my math work.
Lesechka [4]

There's not much math work here, they just want you to eyeball the graph and give the closest grid point to where the two lines meet.

Let's translate the question.

Solution to the system

That's the x and y values where the two lines cross.  That's because the meeting point is the value of x and y that satisfies both equations.

Approximation ... to the nearest integer values

Where two integer grid lines cross is called a lattice point.  It's a point with integer coordinates.  Our solution, the meet of these two lines, doesn't fall exactly on a lattice point.  The nearest integer values means the closest lattice point to our intersection of lines.

Eyeballing the graph, I'd say (x,y)=(2,3) is the closest point.

Answer: (2,3)   second choice
