The length of the cable will be 6 feet which can be installed  120-volt/15-amp circuit.

<h3>What is an ampere circuit?</h3>

Ampere's circuital law states that “the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.”

Here we have a cable rating of 120-volt/15-amp so if the 1-ampere circuit means 1 watt per foot cable will be used for the 1-ampere circuit.

A Total of the 15-ampere circuit means 15 watts needed so we are using 2.5 watts per foot.

\rm Length \ of\  Cable =\dfrac{15}{2.5}=6 \ \ foot

Hence the length of the cable will be 6 feet which can be installed  120-volt/15-amp circuit.

Which of the following is NOT true about​ P-values in hypothesis​ testing? Choose the correct answer below. A. If the P is​ high
pashok25 [27]

Answer:

Step-by-step explanation:

In statistical hypothesis testing we use p values.  For any test we select significance level alpha as 5% or 1% or 10%

Whenever p < alpha we reject our null hypothesis.  Otherwise we accept our null hypothesis.

Hence p should be high to accept null hypothesis

Option A is incorrect

B is correct

C is wrong as p is the probability

D False

Option B is right.

On a coordinate plane, 2 polygons are shown. Polygon A B C D has points (1, negative 6), (5, negative 6), (6, negative 2), and (
irga5000 [103]

Answer:

The correct option is;

Use a scale factor of 2

Step-by-step explanation:

The parameters given are;

A = (1, -6)

B = (5, -6)

C = (6, -2)

D = (0, -2)

A'' = (1.5, 4)

B'' = (3.5, 4)

C'' = (4, 2)

D'' = ( 1, 2)

We note that the length of side AB in polygon ABCD = √((5 -1)² + (-6 - (-6))²) = 4

The length of side A''B'' in polygon A''B''C''D'' = √((3.5 -1.5)² + (4 - 4)²) = 2

Which gives;

AB/A''B'' = 4/2 = 2

Similarly;

The length of side BC in polygon ABCD = √((6 -5)² + (-2 - (-6))²) = √17

The length of side B''C'' in polygon A''B''C''D'' = √((4 -3.5)² + (2 - 4)²) = (√17)/2

Also we have;

The length of side CD in polygon ABCD = √((6 -0)² + (-2 - (-2))²) = 6

The length of side C''D'' in polygon A''B''C''D'' = √((4 -1)² + (2 - 2)²) = 3

For the side DA  and D''A'', we have;

The length of side DA in polygon ABCD = √((1 -0)² + (-6 - (-2))²) = √17

The length of side D''A'' in polygon A''B''C''D'' = √((1.5 -1)² + (4 - 2)²) = (√17)/2

Therefore the Polygon A B C D can be obtained from polygon A''B''C''D'' by multiplying each side of polygon A''B''C''D'' by 2

The correct option is therefore;

Use a scale factor of 2.
