If x+3/3 = y+2/2 then x/3 =

1 answer:

5 0

I'd say first isolate the "x"
(x+3)/3=(y+2)/2
x+3=3*(y+2)/2
x=3(y+2)/2 -3

so we get "x" equals three times "y" plus two which is then divided by two and subtracted by three.

after that I would simply divide both sides by three as shown below

x/3=( 3*(y+2)/2 -3)/3

x/3 =(y+2)/2 -1 (answer simplified)

Answer: 9,000,000

Explanation: Using Pemdas, the first thing you do is solve the exponent, so 10^6 is 10 x 10 x 10 x 10 x 10 x 10 which is 1,000,00 and then you do the multiplication which makes the problem equal 9,000,000. Hope this helped!!

Paul [167]

Answer:

Una unidad rack o simplemente U es una unidad de medida usada para describir la altura del equipamiento preparado para ser montado en un rack de 19 ó 23 pulgadas de ancho. Una unidad rack equivale a 1,75 pulgadas (44.45 mm) de alto.

Una unidad de rack se escribe normalmente como "1U"; del mismo modo dos unidades se escribe "2U" y así sucesivamente. La altura de una pieza del equipamiento de un rack es frecuentemente descrita como un número en "U".

kirill115 [55]

Answer:

$0.60 - 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.570$

$0.60 + 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.630$

The 95% confidence interval for the true proportion would be given by (0.570;0.630) .

And if we convert this into % we got (57.0%, 63.0%)

Step-by-step explanation:

The information given we have the following info given:

$n = 1019$ represent the sampel size

$\hat p=0.6$ represent the sample proportion of interest

The confidence level is 95%, our significance level would be given by $\alpha=1-0.95=0.05$ and $\alpha/2 =0.025$ . And the critical value would be given by:

$z_{\alpha/2}=-1.96, z_{1-\alpha/2}=1.96$

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

$\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}$

Replacing the info given we got:

$0.60 - 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.570$

$0.60 + 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.630$

The 95% confidence interval for the true proportion would be given by (0.570;0.630) .

And if we convert this into % we got (57.0%, 63.0%)

Find the terminal point on the unit circle determined by 5pi/4 radians

zimovet [89]

The terminal point represented by P(x,y), is the coordinate where a certain point lies. Given is 5pi/4 radians - this will be our angle.

Evaluate the values of x and y using sin θ and cos θ

x = cos (5pi/4)
x = -√2/2

y = sin (5pi/4)
y = -√2/2

Therefore, (x,y) is (-√2/2, -√2/2)
