Answer:Company Z provides electricity for 8 houses.

Step-by-step explanation:

The total number of houses in the neighborhood is 40.

Company X provides electricity to 1/5 of the houses. This means that the number of houses that Company X provides for would be

1/5 × 40 = 8

Company Y provides electricity to 3/5 of the houses. This means that the number of houses that Company Y provides for would be

3/5 × 40 = 24

Company Z provides electricity to the remaining houses. Therefore,

the number of houses that Company Z provides for would be

40 - ( 8 + 24) = 40 - 32 = 8

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.

If sine ⁡theta equals negative 8/17 and the terminal side of theta lies in quadrant IV, find cosine ⁡ theta .
Lelechka [254]
\sin^2\theta+\cos^2\theta=1\implies \cos\theta=\pm\sqrt{1-\sin^2\theta}

Since \sin\theta=-\dfrac8{17}, it follows that

\cos\theta=\pm\sqrt{1-\dfrac{64}{289}}=\pm\sqrt{\dfrac{225}{289}}=\pm\dfrac{15}{17}

where the sign depends on the location of the terminal side of the angle. Since the terminal side lies in the fourth quadrant, that means the cosine of the angle is positive, so

\cos\theta=\dfrac{15}{17}

Find (f°g)(x) f(x)=x^2-1, g(x)=3x-2
Bess [88]
F°g(x) = (3x-2)² -1
= 3x(3x-2)-2(3x-2) -1
= 9x² -6x-6x+2-1

Describe the faces, edges, verticals of each three dimensional figure. Then identify it.
EastWind [94]

When you have to describe a 3D shape you have to keep the following definitions in mind:

<em>1. The face of a 3D shape is a flat surface.</em>

The shape on the picture has 3 rectangular faces and 2 triangular faces, a total of 5 faces.

<em />

<em>2. The edge is where two faces meet.</em>

For the shape on the picture, there are 3 edges, where the rectangular faces meet each other, and then three edges where the rectangular faces meet each of the triangular faces, this shape has a total of 9 edges.

<em>3. The vertex is a corner, where the edges meet.</em>

There are three vertices on each end of the shape, so it has a total of 6 vertices.

A shape that has 5 faces, 9 edges, and 6 vertices is a triangular prism.
