Answer:

Step-by-step explanation:

480 = 100%

72  =   ?       you can find it doing  (72(100))/480

72(100)= 7200      

7200/480= 15

sveta [45]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data :

Technician __Shutdown

Taylor, T___4

Rousche, R _ 3

Hurley, H__ 3

Huang, Hu___2

Gupta, ___ 5

The Numbe of samples of 2 possible from the 5 technicians :

We use combination :

nCr = n! ÷ (n-r)!r!

5C2 = 5!(3!)2!

5C2 = (5*4)/2 = 10

POSSIBLE COMBINATIONS :

TR, TH, THu, TG, RH, RHu, RG , HHu, HG, HuG

Sample means :

TR = (4+3)/2 = 3.5

TH = (4+3)/2 = 3.5

THu = (4+2) = 6/2 = 3

TG = (4 + 5) = 9/2 = 4.5

RH = (3+3) = 6/2 = 3

RHu = (3+2) /2 = 2.5

RG = (3 + 5) = 8/2 = 4

HHu = (3+2) = 2.5

HG = (3+5) = 8/2 = 4

HuG = (2+5) / 2 = 3.5

Mean of sample mean (3.5+3.5+3+4.5+3+2.5+4+2.5+4+3.5) / 10 = 3.4

Population mean :

(4 + 3 + 3 + 2 + 5) / 5 = 17 /5 = 3.4

Population Mean and mean of sample means are the same.

This distribution should be approximately normal.

Solve using any method. All work must be shown and handwritten.
Rashid [163]

Answer:

x =  - 3

y = 1

Step-by-step explanation:

Write the system

3x - y =  - 10

x + y =  - 2

Solve by Elimination.

multiply the second equation by -3.

3x - y =  - 10

-3x   - 3y =  6

Add the Equations.

- 4y =  - 4

y = 1

Plug this back in one of the equations.

x + 1 =  - 2

x =  - 3

The system with one and only one solution set is called a/an system
beks73 [17]

Answer:

Consistent and Independent System

Step-by-step explanation:

A system with at least one solution is a consistent system.  A consistent system is said to be independent if it has <u>exactly one solution</u> (often referred to as the <em>unique</em> solution).  The graphs intersect at exactly one point, which gives an ordered-pair (x, y) as the solution of the system.

12. (07.06 LC) A library building is in the shape of a rectangle. Its floor has a length of (3x + 5) meters and a width of (5x −
Goshia [24]

ANSWER

15 {x}^{2} + 22x - 5

EXPLANATION

It was given that, the length of the rectangular building is

(3x + 5) \: meters

and the width of the is

(5x - 1) \: meters

The area of a rectangular building is calculated using the formula for finding the area of a rectangle.

A = l \times w

Since the dimensions are given in terms of x, the area is also a function of x,

A(x) = (3x +5 )(5x - 1)

We expand to get,

A(x) = 3x(5x - 1) + 5(5x - 1)

A(x) = 15 {x}^{2}  - 3x + 25x - 5

A(x) = 15 {x}^{2} + 22x - 5

meters square
