z varies directly with x and inversely with y. When x = 6 and y = 2, z = 15. What is the value of z when x = 4 and y = 9?
cupoosta [38]

Answer: z =2.22

Step-by-step explanation:first determine the constant. Z= K(X/Y) if z is 15, x is 6 and y is 2 then 15= K(6/2) then K is 5.

When x is 4 and y is 9 . k is 5 then

Z ,= 5(4/9) = 2.2.

Descubriendo los triples pitagóricos – Explicado

El Teorema de Pitágoras es ciertamente uno de los teoremas más famosos en todas las matemáticas. Tanto los matemáticos como los laicos lo han estudiado durante siglos, y la gente lo ha demostrado de muchas maneras diferentes. (Incluso al presidente James Garfield se le atribuyó una prueba nueva y original.) Así que sin más preámbulos, aquí está:

El Teorema de Pitágoras: La suma de los cuadrados de las piernas (los dos lados más cortos) de un triángulo recto es igual al cuadrado de la hipotenusa (el lado más largo).

Si usted escoge cualquier número antiguo para dos de los lados de un triángulo rectángulo, el tercer lado usualmente termina siendo irracional – usted sabe, la raíz cuadrada de algo. Por ejemplo, si las patas son 5 y 8, la hipotenusa termina siendo la raíz cuadrada de 89, o aproximadamente 9.43398 ….. (el decimal continúa para siempre sin repetirse). Y si escoges números enteros para la hipotenusa y una de las patas, la otra pata suele terminar siendo la raíz cuadrada de algo.

Answer:

9.9676 - 2.326*0.5904 =8.594

9.9676 + 2.326*0.5904 =11.341

Step-by-step explanation:

Notation

\bar X represent the sample mean

\mu population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size  

Solution to the problem

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

For this case the 9% confidence interval is given by:

8.8104 \leq \mu \leq 11.1248

We can calculate the mean with the following:

\bar X = \frac{8.8104 +11.1248}{2}= 9.9676

And we can find the margin of error with:

ME= \frac{11.1248- 8.8104}{2}= 1.1572

The margin of error for this case is given by:

ME = t_{\alpha/2}\frac{s}{\sqrt{n}} = t_{\alpha/2} SE

And we can solve for the standard error:

SE = \frac{ME}{t_{\alpha/2}}

The critical value for 95% confidence using the normal standard distribution is approximately 1.96 and replacing we got:

SE = \frac{1.1572}{1.96}= 0.5904

Now for the 98% confidence interval the significance is \alpha=1-0.98= 0.02 and \alpha/2 = 0.01 the critical value would be 2.326 and then the confidence interval would be:

9.9676 - 2.326*0.5904 =8.594

9.9676 + 2.326*0.5904 =11.341
