Choose the correct equation type for each system.
Lunna [17]

Answer:

Inconsistent= 1, & 3

Equivalent= 2&6

Consistent= 4&5

Step-by-step explanation:

Equivalent means both sides of the equation has similar results

Consistent means the equation has an order pair of x, y that make it true

Inconsistent means impossible to solve using a set of values for the variable

1. y=3x-2

  3x-y=4----------------make y subject of equation as 3x-4=y

Equate the two equation

y=3x-2

y=3x-4

3x-2=3x-4---------------collect like terms

3x-3x=-4+2

0=-2---------------inconsistent

2. 1/2 y=-x+5------------multiply by 2 both sides to have y=-2x+10

    2y=-4x+2

we have

y=-2x+10----------------------use y in this equation in the second equation

2y=-4x+20

2(-2x+10)=-4x+20

-4x+20=-4x+20----------------Equivalent

3. y=-x+4----------------use this in the second equation as

   x=-y-6

x= - (-x+4)-6

x= x-4-6

x=x-10--------------collect like terms

x-x= -10

0= -10--------------inconsistent

4. y=4x+2

   y=6x-10-----------equate the two

4x+2=6x-10----------collect like terms

4x-6x=-10-2

-2x=-12

x=6---------------------use to find y

y=4(6)+2=24+2=26

(x,y)=(6,26)---------consistent

5. y=2x+1

   y=-2x+3

Equate the two equation

2x+1=-2x+3-------------collect like terms

2x+2x=3-1

4x=2

x=1/2----------use to find y

y=2 *1/2 +1 =1+1=2

(x,y) = (1/2, 2)---------------consistent

6. -2x +5y=0

   y=2/5x-------------------use this in the first equation

   -2x + 5(2/5 x)=0

   -2x+2x =0

0=0-----------------------Equivalent

Normal Distribution
MariettaO [177]

Answer:

No

Step-by-step explanation:

<u>Explanation</u>:-

  • The graph of the normal distribution y = f(x) in the x y- plane is known as normal curve.The curve is bell shaped and symmetrical about the line x = μ

        So The first statement is not true because symmetrical about the line        x = μ not 'm'

  • Area under normal curve represents the total population

so the total area under the curve is 100 or one so  The second statement is true

  • The normal distribution for mean is zero and standard deviation is one is known as standard normal distribution.
  • 95 percentage within two standard deviations
  • 99.7 percentage of the data are within three standard deviations of the mean.
  • 68 percentage of the data are within one standard deviation

All above points are true so In given data the third statement is not true

95 percentage within two standard deviations not one

  • The fourth statement is false because 68 percentage of the data are within one standard deviation not 34 percentage.
  • All data sets are normally distributed its depend on given data
