Answer:

1.) n = - 5/2

2.) No solution

3.) n = - 2/5

Step-by-step explanation:

1.) n(- 2) = - 1 - (- 2) + 4

- 2n = - 1 + 2 + 4

- 2n = 5

n = - 5/2

2.) n(0) = - 1 - (0) + 4

0 = - 1 - 0 + 4

0 = 3

No solution

3.) n(5) = - 1 - (5) + 4

5n = - 1 - 5 + 4

5n = - 2

n = - 2/5

Can someone please put 1 1/4 cups 0.4 L 950 mL and 0.7 gallons in greatest to least

Yuliya22 [10]

Answer:

0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups

Step-by-step explanation:

First we need to convert the information given into one unit, in this case I will convert it into liters (L)

CUPS

1 cup is equal to 236.588 ml and is the same as .236 L using this information and knowing that 1 1/4 cup is the same as 1.25 cups we have that

$x=\frac{1.25\times .236}{1}$

x=.295 L

LITERS

0.4 L will stay the same

MILILITERS

1 liter is 1000 ml so 950 ml is the same as

$x=\frac{950 \times 1}{1000}$

x=.950 L

GALLONS

1 gallon is 3.78541 L so 0.7 gallons are

$x=\frac{0.7 \times 3.785}{1}$

x=2.649 L

arranging the data from greatest to least we have that 0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups

Identify the slope and y-intercept of the line x+2y=−2.

Reil [10]

Answer:

slope: -1/2

Y-intercept: -1

Step-by-step explanation:

Get Y by itself by subtracting x on both sides

2y= -x -2

Now divide both sides by 2 to cancel the two connected to the y:

Y = -1/2x -2/2

So y= -1/2x -1

Y=mx+b so m is the slope and b represents the y-intercept

What is the median for the given set of data?

Naily [24]

Step-by-step explanation:

Arranging in ascending order, we get

13 , 22 , 30 , 33 , 40 , 54 , 55

no of data (N) = 7

Now Position of Median

= {(N +1 ) / 2}th item

= {(7+1) / 2 } that item

= 4 that item

So now exact median = 33
