Answer:

1. Nominal Scale; 2. Ordinal Scale; 3. Ordinal Scale; 4. Nominal Scale.

Step-by-step explanation:

<h3>Q1 and Q4</h3>

The variable in Question 1 (Q1)<em> </em>could be described as <em>The</em> <em>attributes of the restaurant, </em>with possible values<em>: </em>service, prices, quality of food, menu options (four values).

The variable in Question 4 (Q4) could be mentioned as <em>Eaten before in the restaurant</em>, with possible values: yes or not (two values).

These values are, in fact, simply names, and although they can be represented using numbers, they have no numerical meaning at all.

For instance, the values in Q1 can be labeled by 0 (service), 1 (prices), 2 (quality of food), 3 (menu options) and 0 (not) or 1 (yes), in Q4; for purposes of data analysis, 3 (menu options) is a label and does not mean a higher score than 1 or 0. <em>These numbers are labels rather than meaningful numbers</em>, and this is a characteristic of the Nominal Scale of measurement. Then, the possible response for questions Q1 and Q4 is the Nominal Scale.

<h3>Q2 and Q3</h3>

The variable in Q2 is the <em>Rating of the restaurant</em>, with possible values: excellent, good, fair, poor.

The variable in Q3 is <em>Prices, </em>with possible values: high, average, low.

As can be seen, any possible value in either question, like excellent or high, has a greater value than fair or low, respectively. In other words, they have different values concerning others, but we do not the <em>distance</em> among them. <em>High</em> is greater than <em>Average</em>, and the latter is greater than the <em>Poor </em>value, but we do not know what distance separates one value from the other, and this is a characteristic of the Ordinal Scale of measurement. Thus, the possible response for questions Q2 and Q3 is the <em>Ordinal Scale</em>.

The Halloween conical hat, with given height, circular base and brim

extension has the following calculated parameters;

Part a. The slant height is <u>18.2 inches</u>

Part b. The volume of the cone is 37\frac{1}{2}  \cdot \pi in.³

Part c. The area of the brim, <em>A</em> = <u>36·π in.²</u>

Part d. The area of the brim is found by <u>subtracting the area of the base of the cone from the area covered by the perimeter of the brim</u>

Reasons:

Known parameters;

Height of the conical portion, h = 18 inches

Base circumference, C = 5·π inches

Part a. Slant height of the conical portion; Required

Solution:

The circumference of a circle, C = 2·π·r

Therefore;

r = \dfrac{C}{2 \cdot \pi}

Which gives;

r = \dfrac{5 \cdot \pi}{2 \cdot \pi} = \dfrac{5}{2} = 2.5

Radius, r = 2.5 inches

According to Pythagoras's theorem, we have; s² = r² + h²

Where;

s = The slant height of the cone

s² = 2.5² + 18² = 330.25

s = √(330.25) ≈ 18.2

  • The slant height, <em>s</em> ≈ <u>18.2 inches</u>

Part b. The measure in cubic inches of candy that exactly fills the conical portion of the hat is the volume of the cone.

Volume \ of \ a \ cone = \dfrac{1}{3} \cdot \pi \cdot r^2 \cdot h

Therefore;

V = \dfrac{1}{3} \times \pi \times 2.5^2 \times  18 = 37\frac{1}{2}  \cdot \pi

  • The volume of the cone, V = 37\frac{1}{2}·π in.³

Part c. The extension of the brim from the base of the cone = 4 inches

The radius of the brim, R = Radius of the base of the cone + 4 inches

∴ <em>R</em> = 2.5 inches + 4 inches = 6.5 inches

Area of the brim, <em>A</em> = Area of the 6.5 inch circle - Area of the circular base of the cone

∴ A = π × 6.5² - π × 2.5² = 36·π

  • The area of the brim, <em>A</em> = <u>36·π in.²</u>

Part d. The procedure for solving the question in part c, is described as follows;

  • The area of the brim can be found by finding the entire area of the circle formed by the perimeter of the brim, then subtracting the area of the base of the cone from that area.

Cayden wants to buy a television that costs $600, including taxes. To pay for the television, he will use a payment plan that re
kobusy [5.1K]

well, the regular cost of the TV is 600 bucks, that includes taxes already, so is just 600 flat.

the payment plan makes Cayden pay 225 first, leaving 375 for periodic payments for 6 months, each payment of 74.50.

well, 74.5*6 = 447, so Cayden is paying 225 + 447 = 672, so the increase is 72 bucks.

If we take 600 to be the 100%, how much is 72 off of it in percentage?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 600&100\\ 72&x \end{array}\implies \cfrac{600}{72}=\cfrac{100}{x}\implies \cfrac{25}{3}=\cfrac{100}{x} \\\\\\ 25x=300\implies x=\cfrac{300}{25}\implies x=12

Can someone please help me <br> Step-by-step explanation please
-Dominant- [34]

Answer:

x=3

Step-by-step explanation:

AB+BC>AC

2x + 3 + x + 1 > x + 10

we correct like terms

2x + x + 3 + 1> x+ 10

3x + 4> x + 10

3x - x > 10-4

2x > 6

divide both sides by 2

2x÷2 > 6÷2

x = 3

serious [3.7K]

Answer:

x = -1

Step by step explanation:

Distribute 6

6x-12= -18

Add 12 to both sides

6x= -6

Divide both sides by 6

x= -1

What is the next step
iragen [17]

Answer:

measure of angle ABC is 6 degree.

Step-by-step explanation:

After you found x, you'll plug it in the equation of the angle it's asking for.

Measure of angle ABD, and you know measure of angle ABC = 4x-1.

4(1)-1 = 4-1 = 3

Measure of angle CBD = 2x+1.

2(1) +1 = 3

Measure of angle ABC is ABD + CBD

3 + 3 = 6
