Range = 79

9. Mean = 31.57

Median = 32

Mode = 46

Range = 34

10. Mean = 42.11

Median = 36

Mode = 51

Range = 51

Step-by-step explanation:

Mean is the average. Mode is the number that appears the most. Median is the middle number. Range is the biggest number minus the smallest number.

Simplify the expression. Write the answer using scientific notation. 0.3(8.2 x 10^-3)

olchik [2.2K]

Answer:

0.3(8.2 x 10^-3) = 2.46 X 10 ^ -3

Step-by-step explanation:

We need to solve the equation 0.3(8.2 x 10^-3) and write answer in scientific notation.

Solving,

= 0.3(8.2 x 10^-3)

= 0.3 * 0.0082

= 0.00246

Writing in scientific notation

= 2.46 X 10 ^ -3

So, after solving the expression 0.3(8.2 x 10^-3) the result is 2.46 X 10 ^ -3.

Answer: The state with the second lowest population has the lowest population density.

Step-by-step explanation:

Since, Density = Population / Area

The population of state A = 1,055,173

Its area = 2677 square km

Thus, the density of state A = $\frac{1055173}{2677}$ = 394.162495,

The population of state B = 1,333,089

Its area = 36,418 square km

Thus, the density of state B = $\frac{1,333,089}{36,418}$ = 36.6052227,

The population of state C = 3,596,677

Its area = 5543 square km

Thus, the density of state C = $\frac{3,596,677}{5543}$ = 648.868302,

The population of state D =6,745,408

Its area = 10555 square km

Thus, the density of state D = $\frac{6,745,408}{10555}$ = 639.072288,

Since, by the above explanation,

The state in increasing order of the populations,

State A < State B < State C < State D,

Also, the state in increasing order of density,

State B < State A < State D < State C

⇒ Second option is correct.
