The given scales which measure the attitude of a person is an ordinal scale such as a Likert scale

<h3>What is an ordinal scale?</h3>

An ordinal scale provides a report of the rating, order or rank of a data without stating the extent of variation between the categories.

There are many types of rating scales used to directly measure the attitude of a person towards a subject matter.

The Likert scale which is the most widely used rating scale, when applied, consists of a five or seven point scale, that empowers the subject of the survey to express how much they agree (or disagree) with a specified statement.

Generally, five options, graded from, mild to extreme are provided so that the survey subject can indicate (express), their strength of how much they agree with or feel about the statement or question

The assumptions of the Likert scale includes;

The ability to measure attitudes.
The intensity or strength of an attitude is linear, such that the attitude varies linearly from strongly agree to strongly disagree

Based on the perception of the subject, Likert scale can be used to also measure the variations of the following subject matters;

Likelihood of an event or occurrence
The importance of a product or service
The quality perception of an object
The frequency of an event

Solve each equation using the quadratic formula. Find the exact solution, then approximate the solution to the nearest hundredth

Anika [276]

Answer:

$x_1=\frac{5+\sqrt{33}}{4}$ ≈2.69

$x_2=\frac{5-\sqrt{33}}{4}$ ≈-0.19

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have that the quadratic formula is:

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

2. To solve the quadratic equation you must substitute the values. So, you have that:

Rewrite the equation:

$2x^{2}-5x-1=0$

$a=2\\b=-5\\c=-1$

Then you have:

$x=\frac{-(-5)+/-\sqrt{(-5)^{2}-4(2)(-1)}}{2(2)}$

3. Therefore, you obtain the following result:

$x_1=\frac{5+\sqrt{33}}{4}$ ≈2.69

$x_2=\frac{5-\sqrt{33}}{4}$ ≈-0.19

a mailing tube in the shape of cylinder has a height of 24 inches and a radius of 3 inches. what is the volume, in cubic inches,

TiliK225 [7]

ANSWER

The volume of the mailing tube is 678.6 square inches to the nearest tenth.

EXPLANATION

The volume of a cylinder is calculated using the formula;

$V=\pi \: {r}^{2} h$

Since the mailing tube is in the form of a cylinder, we use this formula to find its volume.

We substitute h=24 and r=3 to obtain,

$V=\pi \times {3}^{2} \times 24$

$V=216\pi {in}^{2}$

$V=678.6{in}^{2}$
