Identify the data level (nominal, ordinal, interval, or ratio) that best describes each of the following cases: a. The title of a randomly selected individual's favorite book Nominal b. The height of a randomly selected semi tractor and trailer on I-70 Ratio c. Placement (1st, 2nd, etc.) within a video game tournament Ordinal d. The temperature in Paris, France at noon Interval

a. The title of a randomly selected individual's favorite book --> Nominal

b. The height of a randomly selected semi tractor and trailer on I 70 --> Ratio

c. Placement (1st, 2nd, etc.) within a video game tournament --> Ordinal

d. The temperature in Paris, France at noon --> Interval

Step-by-step explanation:

Required

The level of measurement of each

The question was submitted along with the (correct) answers; So, I will provide the explanations

(a) When data are measured using tags and labels; the level of measurement is Nominal

In (a), the data are measured using titles; this represents nominal level

(b) When data are measured using differences or intervals; the level of measurement is Ratio.

In (b), the data are represented using ratio such as 1 - 70 (i.e. 1 to 70); this represents ratio level

(c) When data are measured using orders such as first, second, etc.; the level of measurement is Ordinal

In (c), the data are categorized using 1st, 2nd, etc...; this represents ordinal level

(d) When data are measured using interpretable and meaningful intervals; the level of measurement is Interval;

In (d), the data are categorized using temperature at a certain interval; this represents interval level

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
