A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone i
kondaur [170]
Given:
Volume of the cone = π r² h/3

radius of the cone is half the radius of the cylinder ⇒ r/2
height of the cone is equal to the radius of the cylinder. ⇒ r

V = 3.14 * (r/2)² * r/3
V = 3.14 * r²/4 * r/3
V = 3.14r³ / 12

kumpel [21]

Writing in scientific notation is writing in power form.

Writing in power form is usually in the form:

X.y × 10ⁿ

We now write 3 920 000 000 000 in this form.

3.92 × 10¹²

Answer :

3.92 × 10¹²

This is the scientific notation.

Hope I helped :)

The difference between the sample statistic and population parameter is called:_______
myrzilka [38]

Answer:

The difference between the sample statistic and population parameter is called sampling error.

Step-by-step explanation:

We are given the following in the question:

  • A sample is a part of population, it is a subset of population.
  • A sample statistic describes the sample. It is a characteristic of sample and different from the population.
  • A parameter describes the population. It is characteristic of a population.
  • A sample may not be able to represent the whole population and this may lead to error.
  • Thus, sampling error is the difference between the sample statistic and population parameter.
  • It arises when the sample is not able to describe the population.

The difference between the sample statistic and population parameter is called sampling error.

Josephine has a rectangular garden with an area of 2x2
sergeinik [125]

Answer:

Fourth example, (2x - 3) and (x + 2), are possible dimensions

Step-by-step explanation:

Let's go through all the responses one by one;

First of all the area of the rectangular garden can be computed through length times width, such that:

(x^2 - 3) * (2) = 2x^2 + x - 6,

(2x + 3) * (x-2) = 2x^2 + x - 6,

(2x + 2) * (x-3) = 2x^2 + x - 6,

(2x - 3) * (x + 2) = 2x^2 + x - 6

Now in each of these examples, it should be that the products are equivalent to the area according to the length by width rule, so let's see which is truly the correct dimensions by justifying whether the product is truly equivalent to the area.

First example:

2 * (x^2 - 3) = 2x^2 - 6

Now 2x^2 - 6 ≠ 2x^2 + x - 6 so the first example is not a possibility,

Second example:

(2x + 3) * (x-2) = 2x^2- x - 6

Now 2x^2- x - 6 ≠ 2x^2 + x - 6 so the second example is not a possibility,

Third example:

(2x + 2) * (x-3) = 2x^2 - 4x - 6

Now 2x^2 - 4x - 6 ≠ 2x^2 + x - 6 so the third example is not a possibility,

Fourth example:

(2x - 3) * (x + 2) = 2x^2 + x - 6

Here 2x^2 + x - 6 = 2x^2 + x - 6 so the fourth example can act as possible dimensions
