storchak [24]3 years ago
4 0

9,11,13,20

20 -9 = 11

Range: 11 so its not 17

11 + 13 = 24

24/2 = 12

Median: 12 so its not 10

9+ 11 + 13 + 20 = 53

53/4= 13.25

Mean: 13.25 so its not 12

IQR: 6.5 so its not 7 or 12

1).3x-y=5
solmaris [256]

Answer:

1). y= -5+3x

2). y= -2x-13

3). y= -6x+2

4). y= -x+4

5). y≈ 0.57x

6). y=2x-9

7). Equation incomplete

8). y=3x+23

Step-by-step explanation:

1).

3x-y=5

<em>Subtract 3x from both sides</em>

-y=5-3x

<em>Multiply both sides by -1</em>

y= -5+3x

2).

y+7= -2(x+3)

y+7= -2x-6

<em>Subtract 7 from both sides</em>

y= -2x-13

3).

y= -10-6(x-2)

y=  -10-6x+12

y= -6x+2

4).

3x=12-3y

<em>Add 3y to both sides</em>

3x+3y=12

<em>Subtract 3x from both sides</em>

3y=12-3x

<em>Divide both sides by 3</em>

y= -x+4

5).

-4x-7y=0

<em>Add 4x to both sides</em>

-7y= -4x+0

<em>Multiply both sides by -1</em>

7y= 4x

<em>Divide both sides by 7</em>

y≈ 0.57x

6).

4x-2y=18

<em>Subtract 4x from both sides</em>

-2y= -4x+18

<em>Multiply both sides by -1</em>

2y=4x-18

<em>Divide both sides by 2</em>

y=2x-9

7).

y= 5-

Equation is incomplete.

8).

y-2=3(x+7)

y-2=3x+21

<em>Add 2 to both sides</em>

y=3x+23

A plant cell has a diameter of 1.3 x 10^-8 kilometer.Is it more appropriate to report the diameter of the plant cell as 1.3 x 10
Andre45 [30]
A plant cell has a diameter of 1.3 x 10^-8 kilometer. It is more appropriate to report the diameter of the plant cell as 1.3 x 10^-2 millimeter because it is easier to understand or to write in a non-scientific form since you just move the decimal place twice to the left. Hope this helps.
