Slope 6; through (0,4)
Agata [3.3K]

Answer:

Y=6X+4

Step-by-step explanation:

Para este ejercicio solo disponemos de dos datos conocidos que son la pendiente que es 6 y un punto de la recta (0,4)

Para hallar la ecuación de la recta usaremos la conocida ecuacion punto pendiente:

Y-Yo=m(X-Xo)

Donde Xo y Yo son respectivamente las coordenadas del punto dado (0,4)

Xo=0

Yo=4

m=6----> m es la pendiente

Entonces remplazamos

Y-4=6(X-0)------>Remplazamos los valores dados

Y-4=6X-0-------->Destruimos los parentesisi aplicando distributiva

Y=6X+4 ----------->Finalmente despejamos el 4 que acompaña a la Y

Step-by-step explanation:

The calculation of sides of a rectangular triangle can be done by applying the Pythagorean theorem (the sum of the squares of the legs is equal to the square of the hypotenuse), both legs must form a right angle, and the value of the hypotenuse must be different from the legs. In the example what you give could be a value of one leg and the other of the hypotenuse.

The historical U.S. mean unemployment insurance benefit was reported to be $238 per week. A researcher in the state of Virginia
prisoha [69]

Answer:

The appropriate alternative hypothesis if he wanted to substantiate his suspicion would be H_{a}: \mu > 238

Step-by-step explanation:

At the null hypothesis, we test that the mean is equal to a certain value.

At the alternate hypothesis, we test that the mean is different, less than or more than the mean value tested at the null hypothesis.

The historical U.S. mean unemployment insurance benefit was reported to be $238 per week.

This means that the null hypothesis is:

H_{0}: \mu = 238

A researcher in the state of Virginia anticipated that sample data would show evidence that the mean weekly unemployment insurance benefit in Virginia was above the national level.

This means that the alternate hypothesis is:

H_{a}: \mu > 238
