Question no 2 please​

Mathematics
1 answer:
ELEN [110]3 years ago
3 0

Answer:

x=0 y=-3

Step-by-step explanation:

2x-y-3 =0

4x+y+3=0

Add the two equations together to eliminate y

2x-y-3 =0

4x+y+3=0

------------------------

6x +0y+0=0

6x = 0

Divide each side by 6

6x/6 =0/6

x =0

Now we can find y

2x-y-3 =0

2(0)-y -3 =0

-y-3 =0

Add y to each side

-y+y -3=0+y

-3 =y

Find the two inequalities that define the region on the grid that is not shaded
hoa [83]

Answer:

y 》 2

y > -x + 3

Step-by-step explanation:

Equation of the bold line:

m = (-3/3) = -1

y = -x + 3

Shaded region is below y=2 (dotted)

So, it's defined by y < 2

Also, it's below the bold line

y 《 - x + 3

Everything outside these is not shaded:

y 》2

and y > -x + 3

Answer:

CV for A = 21.8%

CV for B = 15.5%

Step-by-step explanation:

The formula for coefficient of variation is:

CV = Standard Deviation / Mean

So,

For A:

Mean = Sum/No. of items

= 391300/14

=$27950

and

SD = $6085.31

CV for A = 6085.31/27950 * 100

=21.77%

Rounding off to one decimal

CV for A = 21.8%

For B:

Mean = Sum/No. of items

= 43.58/11

=3.96

and

SD = 0.615

CV for B = 0.615/3.96 * 100

=15.53%

=15.5% ..
