Answer: 35.12\text{ persons per square mile}

Step-by-step explanation:

Given: The area of a city = 598 square miles

The population of city = 21,500 people.

The population density for a city is given by :-

\text{Population density }=\frac{\text{Number of people }}{\text{Land area}}\\\\\Rightarrow\ \text{Population density }=\frac{21000}{598}\\\\\Rightarrow\ \text{Population density }=35.11705\approx35.12\text{ persons per square mile}

Hence, the population density of a city  = 35.12\text{ persons per square mile}

Step-by-step explanation:

7 -sqrt(10)

-----------------------

3 sqrt(5) *sqrt(3)

7 -sqrt(10)

-----------------------

3 sqrt(15)

Multiply the top and bottom by sqrt(15)/ sqrt(15)

7 -sqrt(10)               sqrt(15)

----------------------- * ------------

3 sqrt(15)                 sqrt(15)


(7 -sqrt(10))* sqrt(15)

-----------------------------------

3 *15

Distribute


7sqrt(15) - sqrt(150)

------------------------------

45

sqrt(ab) =sqrt(a) sqrt(b)

150 = 25*6

7sqrt(15) - sqrt(25)sqrt(6)

------------------------------

45

7sqrt(15) - 5sqrt(6)

Step-by-step explanation:

Given value:

\to \mu= 711\\\\\to \sigma= 80\\\\\to P(Z >0.84) = 0.20\\\\\to z = 0.84

The formula for z-score:

\to x = z \times  \sigma + \mu \\\\\to x = 0.84 \times 80 + 711 \\\\ \to x=67.2 +711\\\\ \to x=  778.2\\\\ \to x= 778
