8 0

Answer:

1) 70 for both of them

2) Plot A's range is 100-50 = 50, Plot B's range is 100 - 40 = 60 so Plot A has the lesser range

3) Plot B's IQR is 85 - 60 = 25, Plot A's IQR is 80 - 65 = 15 so Plot B has the greater IQR

4) A: 80, B: 85

5) A: 65, B: 60

6) 50

7) 100

8) Plot B, see #2 for work

What value of x is in the solution set of –5x – 15 > 10 + 20x? –2 –1 0 1
stealth61 [152]

Answer:

-2

Step-by-step explanation:

5x – 15 > 10 + 20x

Subtract 5x from each side

5x – 15-5x > 10 + 20x-5x

-15 > 10+15x

Subtract 10 from each side

-15-10 >15x

-25 > 15x

Divide each side by 15

-25/15 > x

-5/3 > x

X must be less than -1  2/3

The only value that is less than -1 2/3 is -2

bricks having volume 500cm^3 each are selected to construct a compound wall of 200m×0.5m×1.5.If theprice of the brick is Rs.14,f
maria [59]

Answer:

Rs. 4,200,000

Step-by-step explanation:

Given :

Volume of brick = 500cm³

Dimension of wall : 200m×0.5m×1.5m

Converting to cm

Volume of compound wall:

(200 * 100) * (0.5 * 100) * (1.5 * 100)

20000cm * 50cm * 150cm=

= 150000000cm³

Volume of compound wall / volume of brick

1500000000 cm³ / 500 cm³

= 300000

Price per brick = Rs. 14

Total price = 14 * 300000 = Rs. 4,200,000

Surface area of a triangular prism = 2B+ph

B is the base area = 6cm²

perimeter p = 12cm

altitude h = 4cm

Substitute

Surface area = 2(6) + 12(4)

Surface area = 12 + 48

Surface area = 60cm²

-5 = -y - 3x<br> Write the equation in slope-intercept form. Please help me. :)​
DaniilM [7]

Answer:

y = -3x + 5

Step-by-step explanation:

You want it in y = mx + b  form

-5 = -y - 3x

Add y to both sides

-5 + y = -y + y - 3x

-5 + y = -3x

Add 5 to both sides

- 5 + 5 + y = -3x + 5

y = -3x + 5
