Answer:

In the state of Kansas, the density of people per square mile is 34.3

Step-by-step explanation:

According to US topographers, the state of Kansas has an area of 213 096 km².

If 1 km² is equal to 0.39 mi², then how much is 213 096 km².

If 1 km² : 0.39 mi².

213,096 km² : 83,107.44 mi²

If the state of Kansas has a population of 2.85 million people, then:

2.85 x10^6 people / 83 107.44 mi² =

34.3 people per square mile.

Alona [7]

Answer:

X is a discrete random variable.

X can take values from 0 to 12:

$X\in[0,1,2,3,4,5,6,7,8,9,10,11,12]$

Step-by-step explanation:

(a) X = the number of unbroken eggs in a randomly chosen standard egg carton

X is a discrete random variable.

The minimum amount of eggs broken is 0 and the maximum amount of eggs broken is 12 (assuming a dozen egg carton).

Then, X can take values from 0 to 12:

$X\in[0,1,2,3,4,5,6,7,8,9,10,11,12]$

About the probability ditribution nothing can be said, because there is no information about it (it can be a binomial, uniform or non-standard distribution).

-14x + 15y = 15 -21x - 20y = -10 Use substitution to find the x and y coordinates.

denis-greek [22]

          -14x + 15y = 15
      -14x + 14x + 15y = 14x + 15
         15y = 14x + 15
          15    15
         y = ¹⁴/₁₅x + 1
   -21x - 20y = -10
   -21x - 20(¹⁴/₁₅x + 1) = -10
-21x - 20(¹⁴/₁₅x) - 20(1) = -10
       -21x - 18²/₃x - 20 = -10
      -39²/₃x - 20 = -10
      + 20 + 20
      -39²/₃x = 10
       -39²/₃   -39²/₃
   x = ⁻³⁰/₁₁₉
         y = ¹⁴/₁₅x + 1
   y = ¹⁴/₁₅(⁻³⁰/₁₁₉) + 1
   y = ⁻²⁸/₁₁₉ + 1
   y = ⁹¹/₁₁₉
      (x, y) = (⁻³⁰/₁₁₉, ⁹¹/₁₁₉)

The area of a square is 64n36 square units. What is the side length of one side of the square?

storchak [24]

Answer:

Step-by-step explanation:

Since the formula for the area of a square is A = x^2, where x is the side length, x = √A.

If A = 64 square units, the side length is √64 units (8 units)

If A = 36 square units, that length is √36 units (6 units)
