Answer:

Marcus will walk 38/3 miles.

Step-by-step explanation:

Given data

Rate of hiking (r): 2 miles per hour = 2 mi/h

Time elapsed (t): 19/3 hours

6 1/3 = 6 + 1/3 = 18/3 + 1/3 = 19/3

We can find the distance (d) that he walks using the following expression.

r = d/t

d = r × t = 2 mi/h × 19/3 h = 38/3 mi = (36 + 2)/3 mi = 12 2/3 mi

Marcus will walk 38/3 miles.

Answer: c. Nominal

Step-by-step explanation:

Level of measurement determines the nature of description .

The four levels of measurements scales are

1. Nominal scale

Categorize the data on the basis of the quality such as Gender, color, etc.

2. Ordinal scale

Order attributes according to their ranks. For example : 1 < 2 < 3 .

3. Interval scale

Describe the feature of the difference between any two categories. For example : Fahrenheit scale to measure temperature.

4. Ratio scale

Consist of the features of nominal, ordinal, and interval measures but in includes a "true zero" point.

For example : Age.

∴ A nominal variable is a qualitative variable such that there is no meaningful ordering or ranking of the categories.

Hence, the correct answer is c. Nominal .

ASHA 777 [7]

Answer:

$n=\frac{8}{3}$ or $n = 2\frac{2}{3}$

Step-by-step explanation:

Multiply both sides of the equation by $\frac{10}{3}$

$(\frac{10}{3}) (\frac{3}{10})*n= (\frac{10}{3})(\frac{4}{5})$

Simplify both sides of the equation.

$n=\frac{8}{3}$ or $n = 2\frac{2}{3}$

hope this helps :)

10 = x + 8

minus 8 from the both sides

10 - 8 = x
