You have to rearrange this so the equation will equal y :

$x + 2y = 5$
Now take away x from both sides. This will leave you with :
$2y = 5 - x$
As you can see the equation is equal to y, however, there is a 2 next to the y so we need to get rid of that.
So 2y basically means : 2* y
And the opposite of * is divide, which means we have to divide both sides by 2, which will leave us with our answer :
$y = (5 - x) \div 2$

In a random sample of 70 people, it was found that 44 of them were fans of the New York Yankees. What is the margin of error for

Veronika [31]

The general formula for the margin of error would be:

z * √[p (1-p) ÷ n]

where:
z = values for selected confidence level
p = sample proportion
n = sample size

Since the confidence level is not given, we can only solve for the
<span>√[p (1-p) ÷ n] part.
</span>
p = 44/70
n = 70

√[44/70 (1 - (44/70) ÷ 70]

√[0.6286 (0.3714)] ÷ 70

√0.2335 ÷ 70

√0.0033357 = 0.05775 or 0.058 Choice B.

Ok, primero haces estas hostilidades de considerable duración y magnitud. En el uso de las ciencias sociales, se agregan ciertas calificaciones. Los sociólogos suelen aplicar el término a tales conflictos sólo si se inician y conducen de acuerdo con formas socialmente reconocidas. Tratan la guerra como una institución reconocida en la costumbre o en la ley. Los escritores militares suelen limitar el término a las hostilidades en las que los grupos contendientes tienen el mismo poder para hacer que el resultado sea incierto durante un tiempo. Los conflictos armados de estados poderosos con pueblos aislados e impotentes suelen denominarse pacificaciones, expediciones militares o exploraciones; con los estados pequeños, se les llama intervenciones o represalias; y con grupos internos, rebeliones o insurrecciones. Tales incidentes, si la resistencia es lo suficientemente fuerte o prolongada, pueden alcanzar una magnitud que les dé derecho al nombre de "guerra".

HELP PLEASE! Thank you

Lostsunrise [7]

Answer:

2000

Step-by-step explanation:

Hello,

A or C means 2 ways

and then a digit means 10 ways 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

so in total we have 2*10*10*10 = 2000 possible codes

Hope this helps

A group of waitresses share tips equally at a local restaurant. All patrons are charged 15% of their total bills in tips for the

ch4aika [34]

Answer:

$88.65

Step-by-step explanation:

To find the amount of total tips, multiply 3,546.12 by 0.15 (the decimal conversion of 15%).

3546.12(0.15) = 531.918

This is the total amount of tips for the night. This is divided evenly between 6 waitresses.

531.918 / 6 = 88.65

EXPLAIN why we placed the value of x= 4/3( the minimum value) into the equ of gradient(dy/dx) [in the answer, marking scheme att

aliina [53]

$y=x(x-2)^2$
$\implies y'=(x-2)^2+2x(x-2)=3x^2-8x+4=(3x-2)(x-2)=0$
$\implies x=\dfrac23,x=2$

are the critical points, and judging by the picture alone, you must have $b=\dfrac23$ and $a=2$ . (You might want to verify with the derivative test in case that's expected.)

Then the shaded region has area

$\displaystyle\int_0^2x(x-2)^2\,\mathrm dx=\dfrac43$

I'll leave the details to you.

Now, for part (iv), you're asked to find the minimum of $\dfrac{\mathrm dy}{\mathrm dx}=y'$ , which entails first finding the second derivative:

$y'=3x^2-8x+4$
$\implies y''=6x-8$

setting equal to 0 and finding the critical point:

$6x-8=0\implies x=\dfrac86=\dfrac43$

This is to say the minimum value of $\dfrac{\mathrm dy}{\mathrm dx}$ *occurs when $x=\dfrac43$ *, but this is not necessarily the same as saying that $\dfrac43$ is the actual minimum value.

The minimum value of $\dfrac{\mathrm dy}{\mathrm dx}$ is obtained by evaluating the derivative at this critical point:

$m=\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{x=4/3}=3\left(\dfrac43\right)^2-8\left(\dfrac43\right)+4=-\dfrac43$
