Step-by-step explanation:
The formulae for standard error = standard deviation/√n
But population standard deviation = 1.8 and sample size = n = 81
Standard error = 1.8/√81 = 1.8/9 = 0.2
Answer:
Using the equation y = abx , substitute both of your given points into that equation.
2 = ab2 and 4 = ab3 Solve each equation for a.
2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3
Cross multiply: 2b3 = 4b2 Divide both sides by b2
2b = 4 a = 2/4 = 1/2
b = 2
y = 1 (2)x
2

Answer: Volume of the cone = 47.12 cubic feet.
Step-by-step explanation:
You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.
To solve for the full volume including the cylinder, use the cylinder's volume formula.
Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.
Volume of a cone is pi(r^2)(h/3)
plug and chug!
h stands for height and r stands for radius.
