X+y+z=6 2×+4y+2z=2 -×+8y-3z=-63

Mathematics
1 answer:
fenix001 [56]2 years ago
3 0

Answer: x=5, y=-5, z=6

Step-by-step explanation:

x+y+z=6 -> 2x+2y+2z=12

subtract 2x+4y+2z=2 from this, and you get -2y=10 -> y=-5

So, x+z=11 and -x-3z=-23

x+z=11

-x-3z=23

---------

-2z=-12

z=-6

Meaning x=5.

Find the domain and the range of the relation shown on the
irinina [24]

The domain of a graph is the possible values of x, the graph can take.

<em>(b) The domain of the relation is the interval [-10,10]</em>

From the attached graph, we have the following observations on the x-axis.

  • <em>The value of x starts from -10</em>
  • <em>The value of x ends at 10</em>

So, the domain of x is from -10 to 10

Using interval notation, the domain of the relation is: [-10,10]

Suppose you just received a shipment of twelve televisions. Three of the televisions are defective. If two televisions are rando
qwelly [4]

Answer: The probability that both televisions work is 0.5625 .

The probability at least one of the two televisions does not​ work is 0.4375.

Step-by-step explanation:

Given : Number of televisions received in shipment= 12

Number of defective televisions received in shipment= 3

Then proportion of defective televisions =\dfrac{3}{12}=0.25

Using binomial probability formula, the probability of getting success in x trials is given by :-

P(x)=^nC_xp^x(1-p)^{n-x}

If two televisions are randomly​ selected, then the probability that both televisions work will be :-

P(0)=^2C_0(0.25)^0(0.75)^2=(0.75)^2=0.5625

The probability at least one of the two televisions does not​ work will be :-

P(x\geq1)=1-P(0)=1-0.5625=0.4375

Find the area created by the overlapping circles given the following information.
lara31 [8.8K]

The area of a circular sector of central angle α (in radians) in a circle of radius r is given by

... A = (1/2)r²×(α - sin(α))


Your area is expected to be computed as the sum of the areas of a sector with angle π/3 in a circle of radius 8 and a sector with angle π/2 in a circle of radius 6.


... A = (1/2)8²×(π/3 - sin(π/3)) + (1/2)6²×(π/2 - sin(π/2))

... A ≈ 16.07


Radii are in inches so the units of area will be in². The appropriate choice is

... 16.10 in²


_____

It should be noted that the geometry described is impossible. Chord CD of circle A will have length 6√2 ≈ 8.4853 inches. Chord CD of circle B will have length 8 inches. They cannot both be the same chord.
