There are 12 jurors sitting in a circle

1 answer:

3 0

I believe you are asking in how many ways they can sit. If so:
The 1st can sit anywhere: he has only 1 way to sit
The 2nd can sit in 11 ways, since one seat is already occupied
The 3rd can sit in 10 ways, since 2 seat are already occupied
The 4th can sit in 9 ways, since 3 seat are already occupied
The 5th can sit in 8 ways, since 4 seat are already occupied
--------------------------------------------------------------------------------
The 12th can sit in 1 way, since11 seat are already occupied
General formula for a circular table:

Number of ways they n persons can be seated: (n-1)!
and the 12 can be seated in (12-1)! = 11! = 39,916,800 ways.
This is called circular permutation

Find the mean of the data set: 9 4 7 3 10 9

almond37 [142]

To find the mean, add up at the numbers and divide by the number of numbers in the set (6)

9 + 4 + 7 + 3 + 10 + 9 =
9 + 11 + 12 + 10
20 + 22
42

42 / 6 = 7

the mean is 7.

Hiroto paid $4.28 in sales tax for the items that he purchased.

Katena32 [7]

Answer:

$68.48

Step-by-step explanation:

You want to find cost such that ...

6.25% × cost = $4.28

Dividing by the coefficient of cost, we get ...

cost = $4.28/0.0625 = $68.48

I only really need the domain and range, intervals, and end behavior. My Precalculus class never covered piecewise functions so

Serjik [45]

(a)

Domain:

we know that domain is all possible values of x for which any function ios defined

Here, curve is defined for all values of x

so, domain is

$(-\infty,\infty)$

Range:

Range is all possible values of y for which x is defined

minimum value of y is -4

maximium value of y is +inf

so, range is

$[-4,\infty)$

(b)

x-intercept:

It is the value of x where f(x)=0

so, the point where curve intersects on x-axis

and we get

$2x^2-4=0$

$x=\sqrt{2}$

and

$x=-5$

(c)

Increasing interval:

where curve is moving upward

we can see that

$(0,\infty)$

Decreasing interval:

where curve is moving downward

we get

$(-\infty,-1)U(-1,0)$

Constant:

constant means horizontal line

there is no horizontal line here

so, it does not exist

(D)

End behavior:

when x-->+inf

y is moving upward

so, y---->+inf

when x-->-inf

y is moving upward

so, y---->+inf

(E)

we can see that curve jupms at x=-1

so, there is discontinuity at x=-1

and this is jump type of discontinuity

(F)

For odd:

f(-x)=-f(x)

For even:

f(-x)=f(x)

we can see that none of them holds true

so, this is neither

Pls help

valina [46]

Answer:

Domain: {1, 2, 3, 4}

Step-by-step explanation:

The domain of the graph (input values) is the number of pizzas which are plotted on the x-axis while the range (output values) is the cost of pizza, plotted on the y-axis (vertical axis)

The domain therefore would consists of each x-coordinate that represent each point on the graph, which are {1, 2, 3, 4}

A large oak tree has 2 × 10 ^ 5 Leaves during its lifespan a large forest can have About 5 × 10 ^ 3 oak trees approximately how

irga5000 [103]

Answer:

1,000,000,000 leaves or 1 x 10^9 leaves

Step-by-step explanation:

One large oak tree has 2 x 10^5 leaves, so we can make that number to 200000

There are 5 x 10^3 oak trees in a forest, we can make that number to 5000

Since we want to find out how many leaves are in the whole forest we multiply: 200000 x 5000 = 1,000,000,000

So approximately there are 1 billion leaves or 1 x 10^9 leaves
