Determine which of the four levels of measurement​ (nominal, ordinal,​ interval, ratio) is most appropriate for the data below.

Social security numbers Choose the correct answer below. A. The interval level of measurement is most appropriate because the data can be ordered comma differences (obtained by subtraction )can be found and are meaningful comma and there is no natural starting point. B. The ratio level of measurement is most appropriate because the data can be ordered comma differences (obtained by subtraction )can be found and are meaningful comma and there is a natural starting point. C. The ordinal level of measurement is most appropriate because the data can be ordered comma but differences (obtained by subtraction )cannot be found or are meaningless. D. The nominal level of measurement is most appropriate because the data cannot be ordered. nothing nothing nothing nothing nothing nothing nothing

Answer:

option D

Step-by-step explanation:

Social security numbers involves numerical quantities but these are only use for identification. Thus, the average social security numbers and other mathematical operations on social security numbers have no significance.

Further, social security numbers doesn't involve order and thus the appropriate measure of scale for this variable in nominal scale.

Constraints are Y <= 40 bags and X=Y in quantity. Nothing else matters.  That's a bad decision unless the chicken farmer lost a poker hand to store X.

A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18pi meters. Wh
ella [17]

Answer

Circumference(C) of a circle is given by:

C = 2\pi r

where r is the radius and value of \pi = 3.14

As per the given statement:

A building engineer analyzes a concrete column with a circular cross section.

The circumference of the column is 18 \pi meters.

then;

18 \pi= 2\pi r

Divide both sides by 2 \pi we have;

9 = r

or

r = 9 meters

We have to find the area of the cross section of the column

Area of a circle is given by:

A = \pi r^2

then;

A = \pi \cdot 9^2 = 81 \pi meter square.

therefore, the area A of the cross section of the column is 81 \pi meter square.

In a right triangle, angle A measures 20°. The side opposite angle A is 10 centimeters long. Approximately how long is the hypot
lubasha [3.4K]
Given that the angle measure 20 and the side opposite to that angle measures 10 cm, suppose this is the height of the triangle, the hypotenuse
Such that
sin theta=opposite/hypotenuse
opposite=a=10 cm
sin 20=10/h
multiplying both sides by h we get
hsin20=10
hence;
h=10/sin20
h=29.24 cm
h=29.2 cm

tino4ka555 [31]

Answer:

0.3425 = 34.25% probability it will be off probation in February 2020

Step-by-step explanation:

We have these desired outcomes:

Off probation in July 2019, with 0.25 probability, then continuing off in January, with 1 - 0.08 = 0.92 probability.

Still in probation in July 2019, with 1 - 0.25 = 0.75 probability, then coming off in January, with 0.15 probability.

What is the probability it will be off probation in February 2020?

p = 0.25*0.92 + 0.75*0.15 = 0.3425

0.3425 = 34.25% probability it will be off probation in February 2020

Agata [3.3K]

Answer:

John ski down the mountain is 1285.37 feet.

Step-by-step explanation:

Given : John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21.

To find : About how far does  John ski down the mountain ?

Solution :

We draw a rough image of the question for easier understanding.

Refer the attached figure below.

According to question,

Let AB be the height of mountain i.e. AB=1200 feet

The angle of depression is 21 i.e. \theta=21^\circ

We have to find how far does  John ski down the mountain i.e. AC = ?

Using trigonometric,

\cos\theta = \frac{AB}{AC}

\cos(21)= \frac{1200}{AC}

AC=\frac{1200}{\cos(21)}

AC=1285.37

Therefore, John ski down the mountain is 1285.37 feet.
