Answer:

C) The survey is meaningless because of voluntary response bias.

Step-by-step explanation:

Voluntary response bias happens when the people that are surveyed volunteer themselves to answer the questions. Only people with a strong opinion, either in favor or against, tend to offer themselves as voluntary subjects.

This same problem happens when radio or TV hosts decide to solicit their audience participation, only people with strong feelings will participate since it is optional. People that are relatively indifferent to the subject will not participate in the survey. This is why most voluntary surveys tend to lean towards extreme answers.

Rasek [7]

Answer:

87 packages

Step-by-step explanation:

First we need to find the volume of the cone-shaped vase.

The volume of a cone is given by:

V_cone = (1/3) * pi * radius^2 * height

With a radius of 9 cm and a height of 28 cm, we have:

V_cone = (1/3) * pi * 9^2 * 28 = 2375.044 cm3

Each package of sand is a cube with side length of 3 cm, so its volume is:

V_cube = 3^3 = 27 cm3

Now, to know how many packages the artist can use without making the vase overflow, we just need to divide the volume of the cone by the volume of the cube:

V_cone / V_cube = 2375.044 / 27 = 87.9646 packages

So we can use 87 packages (if we use 88 cubes, the vase would overflow)

11. Sara borrowed *60,000 from a money lender at 15% rate of interest per annum. What is
patriot [66]

Answer:

<em>36000</em>

Step-by-step explanation:

Given the following

Principal = 60,000

Rate = 15%

Time = 4years

Using the simple interest formula

SI = PRT/100

SI = 60000*15*4/100

SI = 600 * 60

SI = 36,000

<em>Hence the interest paid after 4 years is 36000</em>

A square corner of 16 square centimeters is removed
oee [108]

Option C:

Area of the remaining paper = (3x – 4)(3x + 4) square centimeter

Solution:

Area of the square paper = 9x^2 sq. cm

Area of the square corner removed = 16 sq. cm

Let us find the area of the remaining paper.

Area of the remaining paper = Area of the square paper – Area of the corner

Area of the remaining = 9x^2-16

                                     = (3x)^2-(4)^2

Using algebraic formula: a^2-b^2=(a+b)(a-b)

                                     =(3x-4)(3x+4)

Area of the remaining paper = (3x – 4)(3x + 4) square centimeter

Hence (3x – 4)(3x + 4)  represents area of the remaining paper in square centimeters.
