The answer is D.

The equation for inverse variation is y=k/x

This can also be represented by ky=x

This is because k varies inversely with x

Just as well as x varies inversely with y

There for since the equation is y=1/4x

We can assume k=1/4

Hope this helps and please give a rate, thanks, and, brainliest. I only need two more to reach virtuoso I would really appreciate it ;)

Please solve this equations y=6x²-5,y=17x-6/x

Amiraneli [1.4K]

Answer:

$x=3, y = 49\\x=0.5, y = -3.5\\x=-0.67, y = -2.31$

Step-by-step explanation:

$y=6x^2-5\\y=17x-\frac{6}{x}$

Let's substitute the first equation into the second one.

$6x^2-5=17x-\frac{6}{x}$

$6x^3-17x^2-5x+6=0$ - Multiply by $x$ and bring all the terms to one side.

I'll use my graphical calculator to solve this but you could factor:

$x=3\\x=0.5\\x=-0.67$ (All rounded to 2 decimal places)

Now we can substitute these $x$ values into an equation for $y$ .

$y=6x^2 - 5$

$x=3, y = 49\\x=0.5, y = -3.5\\x=-0.67, y = -2.31$

Use the Euclidean algorithm to find the greatest common divisor d of 313,626 and 152,346. Then use this algorithm to find intege

Marat540 [252]

313,626 = 2 * 152,346 + 8934

152,346 = 17 * 8,934 + 468

8,934 = 19 * 468 + 42

468 = 11 * 42 + 6

6 divides 42, so the GCD of 313,626 and 152,346 is 6.

Lilit [14]

Answer:

it cannot be considered unusual if there was 1 telephone user in this sample without a landline

Step-by-step explanation:

Given that a recent survey found that 30% of telephone users have switched completely to cell phone use (i.e. they do not have landlines in their homes)

Each telephone user is independent of the other and hence prob for switching to cell phone has constant probability 0.30

X the no of customers who switch to cell phones from the sample of 10 is

Binomial with n =10 and p = 0.30

Prob (x=1) = Prob there was 1 telephone user in this sample without a landline

= $10C1 (0.3)^1 (0.7)^9\\= 0.1211$

This is not very near to 0.

Hence this is not a rare event.

So it cannot be considered unusual if there was 1 telephone user in this sample without a landline
