There are three nursing positions to be filled at Lilly Hospital. Position 1 is the day nursing supervisor; position 2 is the ni

Stels [109]

Answer:

There are 1716 ways the three positions can be filled by these applicants.

Step-by-step explanation:

Permutation is the number of arrangement of <em>k</em> items from <em>n</em> distinct items.

$^{n}P_{k}=\frac{n!}{(n-k)!}$

For example, permutation can be used to compute the number of ways to arrange 4 mathematics books together when arranging all the 7 books on a shelf.

In this case there are 3 available nursing positions to be filled.

A total of 13 candidates are qualified for all the three positions.

Then the number of ways the 3 positions can be filled by the 13 candidates can be determine using permutation.

Compute the possible number of selections as follows:

$^{13}P_{3}=\frac{13!}{(13-3)!}=\frac{13!}{10!}=\frac{13\times 12\times 11\times 10!}{10!}=1716$

Thus, there are 1716 ways the three positions can be filled by these applicants.

What is the completely factored form of x4y – 4x2y – 5y? y(x2 – 5)(x2 1) y(x2 5)(x2 – 1) (x2y – 5)(x2 1) (x2y 5)(x2 – 1)

Gala2k [10]

Answer:

y (x² + 1) (x² - 5)

Step-by-step explanation:

<h3>Factorization:</h3>

Take 'y' from each term.

x⁴y - 4x²y - 5y = y[x⁴ - 4x² - 5]

Now factorize x⁴ - 4x² - 5.

Sum = -4

Product = -5

Factors = -5 , 1

When we add (-5) + 1, it gives (-4) and when we multiply (-5)*1, gives (-5).

x⁴ - 4x² - 5 = x⁴ + x² - 5x² - 5

= x²(x² + 1) -5(x² + 1)

= (x²+ 1) (x² - 5)

x⁴y - 4x²y - 5y = y (x² + 1) (x² - 5)

Find the volume of the figure. Round your answer to the nearest tenth if necessary

malfutka [58]

Answer:

The volume of the figure is $8\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a triangular pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base

H is the height of the pyramid

Find the area of the triangular base B

$B=\frac{1}{2}(3)(4)=6\ ft^{2}$

we have

$H=4\ ft$

substitute the values

$V=\frac{1}{3}(6)(4)=8\ ft^{3}$
