Area = 1/2 x base x height
120 = 1/2 x 15 x base = 15/2 x base
base = (2 x 120)/15 = 16 in.

A population has parameters
Ket [755]

Based on the population mean, the mean of the distribution sample means would be 204.6. The standard deviation would be 0.22.

<h3>What are the mean and standard deviation of the distribution?</h3>

The mean of the distribution sample means is the same as the population means which is 204.6.

The standard deviation can be found as:

σₓ = σ / √n

= 3.1 / √197

= 0.22

What is the volume of a cone with a height of 10.5 inches and a radius of 8 inches? cone v = 1 3 bh 1. rewrite the formula for t
bonufazy [111]

The volume of the cone that has a radius of 8 in. and a height of 10.5 in. is: 703.7 in.³

<h3>What is the Volume of a Cone?</h3>

Volume = 1/3πr²h

Given the parameters:

  • Height (h) = 10.5 in.
  • Radius (r) = 8 in.

Volume of the cone = 1/3πr²h = 1/3π(8²)(10.5)

Volume of the cone = 1/3π(64)(10.5)

Volume of the cone = 703.7 in.³

4. The revenue of a company for a given month is represented as ????(x) = 1,500x − x^2 and its costs as ????(x) = 1,500 + 1,000x
mrs_skeptik [129]

Answer:

The profit will be maximum on x = 250.

Step-by-step explanation:

From the given information:

Revenue = 1500x - x²

Cost = 1500 + 1000x

As we know that

Profit = Revenue - Cost ; Let say it equation 1

Then after putting the values of revenue and cost in equation 1 we have:

Profit = (1500x - x²) - (1500 + 1000x)

Profit = 1500x - x² - 1500 - 1000x

Profit = -x² + 500x - 1500

We know that at the max or min the slope of the graph formed by the profit function will be zero, therefore we find the slope of profit function by taking the first derrivative w.r.t. x as under:

d(Profit)/dx = d/dx(-x² + 500x - 1500)

d(Profit)/dx = -2x + 500

By putting the above slope equal to zero we get:

d(Profit)/dx = -2x + 500 = 0

-2x + 500 = 0

-2x = -500

x = 250

Therefore it is concluded that the profit will be maximum when x will be equal to 250.

In 1992, the population of Seoul. South Korea was 17,334,000. In 1995, the population of Seoul was 19,065,000. Find the average
gizmo_the_mogwai [7]
577,000, there is an average change of 577,000 people per year.

To find the average rate of change of the population of people per year, we first need to find the population change per any amount of time, and then divide by how much time that is (in this case, three years). We can find the population change by <u>subtracting </u>the values 17,334,000 and 19,065,000. Subtracting them, we get a change of 1,731,000 in three years. Now, to find the average rate of change of the population in people per year, we divide by three, which gives us our answer of 577,000 people, on average, per year.
