one year: 250/70=25/7 which will be rounded up to 4
250*2-(4*2)=500-8=492
492+300=792
Which means that around 792 chicken turtles in the habitat 12 years after the initial release.

The cost of a week long vacation in a city has a mean of 1000 and a variance of 1200. The city imposes a tax which will raise al

matrenka [14]

Answer:

The coefficient of variation after the tax is imposed is 0.033

Step-by-step explanation:

Given

$\mu =1000$ --- mean

$\sigma^2 = 1200$ --- variance

$tax = 10\%$

Required

The coefficient of variation

The coefficient of variation is calculated using:

$CV = \frac{\sqrt{\sigma^2}}{\mu}$

After the tax, the new mean is:

$\mu_{new} = \mu * (1 + tax)$

$\mu_{new} = 1000 * (1 + 10\%)$

$\mu_{new} = 1100$

And the new variance is:

$\sigma^2_{new} = \sigma^2 * (1 + tax)$

$\sigma^2_{new} = 1200 * (1 + 10\%)$

$\sigma^2_{new} = 1320$

So, we have:

$CV = \frac{\sqrt{\sigma^2}}{\mu}$

$CV = \frac{\sqrt{1320}}{1100}$

$CV = \frac{36.33}{1100}$

$CV = 0.033$

What is the range of Variable A for the cluster?

katovenus [111]

1. The range is the possible values for the y-coordinate in a relation or a set of data pairs.
The range is {nine, ten, eight, five, four, two}

2. If you plot the given points, then you'd see that that point
(three, nine) is far from the rest of the other points which makes it an outlier. Other methods can be used to determine whether or not the point is really and outlier. For now, a visual inspection is enough.

2x – 4y = 14<br> x = 2y – 2<br><br> What is the solution to the system?

AVprozaik [17]

Answer:

No Solution.

Step-by-step explanation:

2x-4y=14

x=2y-2

----------------

2(2y-2)-4y=14

4y-4-4y=14

-4=14

no solution
