Answer:

1st  Qtrl:  11

Median:  20.5

3rd Qtrl:  25.5

Range:  22

Step-by-step explanation:

Median = average of 2 middle values (18 + 23) / 2

1st Qtrl = average of 10 and 12 (the lower half of data)

3rd Qtrl = average of 25 and 26 (the upper half of data)

Range = largest value - smallest value;  30 - 8 = 22

An employee at a fireworks company is designing a rocket. The rocket will consist of a cardboard circular cylinder with a height
Andreyy89

The radius of the cylinder should be approximately 2.040 inches long.

<h3>How to calculate the radius of a rocket to contain a required quantity of powder</h3>

The volume required to store the powder is the sum of the volumes of the cylinder and the cone, whose expression is in this case:

204 in³ = (π/3) · r² · (4 in) + π · r² · h

204 in³ = (4/3 + h) · π · r²

204 in³ = (4/3 + 7 · r) · π · r²

204 = (4π/3) · r² + 7π · r³

7π · r³ + (4π/3) · r² - 204 = 0

The <em>positive</em> roots of the <em>cubic</em> equation are:  

r ≈ 2.040 in

The radius of the cylinder should be approximately 2.040 inches long.

How does one solve this question, any help would be appreciated! I feel this has a really easy solution and I've decided to sign
arsen [322]
Hello,

a)
the gradient is the slope:

y+2=3(x-0) or y=3x-2

b) slope is -5 (parallele to y=-5x+4)

y+1=-5(x-0) or y=-5x-1
