g) c=1.98w is your answer
w = weight = 5.5
c = cost = 10.89
10.89 = 1.98(5.5)
10.89 = 10.89 (true)
hope this helps
To get slope use
y2 - y1 / x2 - x1
10 - 8 / 1 - 0 = 2/1 = 2
Slope = 2
The y-intercept is the coordinate point that has 0 as the x value.
(0, 8) is the y-intercept.

Deviation, d = x -y
Sample mean for the deviation


Standard deviation: 


SD =2.93
Under the null hypothesis, the formula for the test statistics will be given by:


Answer:
Step-by-step explanation:
The total surface area of the sphere = 2πr²
Total surface area of the cylinder = 2πr²+2πrh
Total surface area of the solid = 4πr²+2πrh
r is the radius of the sphere and the cylinder
h is the height of the cylinder
Total surface area of the solid = 2πr(r+h)
If the total height of the solid is 18 cm, then r+h = 18cm
Given the Total surface area of the solid = 205π cm
205π = 2πr(r+h)
205π = 2πr(18)
205π = 36πr
205 = 36r
Divide both sides by 36
205/36 = 36r/36
r = 5.69cm
Since r+h = 18cm
5.69+h = 18
h = 18-5.69
h = 12.31cm
