If the population of Alaska in 2000 was
madreJ [45]

Using mathematical operations, the population of Alaska in 2050 will be 8,99,500.

<h3>What are mathematical operations?</h3>
  • An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
  • The operation's arity is determined by the number of operands.
  • A mathematical action is called an operation. Mathematical operations include addition, subtraction, multiplication, division, and finding the root.

So, the population in 2050:

  • Population increases from 2000 to 2020:
  • 733,000 - 622,000 = 1,11,000
  • Population change in 20 years = 1,11,000
  • In 10 years = 1,11,000/2 = 55,500

So, poulation in 5050:

  • 2020 (20 years) ⇒ 2040 (00 years) ⇒2050
  • = 733,000 + 1,11,000 + 55,500
  • = 8,99,500

Therefore, using mathematical operations, the population of Alaska in 2050 will be 8,99,500.

A backyard pool has a concrete walkway around it that is 5' wide on all sides the total area of the pool and the walkway is 950'
Soloha48 [4]

The dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0

<h3>How to determine the dimension</h3>

For the pool, we have that;

Let the width = x feet

Length = (x+8) feet

The pool alongside the walkway gives;

Width = x + 5 + 5 = (x + 10) feet

Length = x + 8 + 5 + 5 = (x + 18) feet

Total area of the pool with walkway = 950 square feet

Note that formula for area is given as

Area = length * width = 950

Equate the length and width

(x+18)  × (x + 10) = 950

Using the  FOIL method, we have;

(x × x )+ (x × 10) + (18 × x) + (18 × 10) = 950

x² + 10x + 18x + 180 -950 = 0  

collect like terms

x² + 28x - 770 = 0

Thus, the dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0

The following chart represents the record high temperatures recorded in Phoenix for April - November. Select the answer below th
svetlana [45]

Answer:

C. The mean is 111.9F and the median is 114.5F.

Step-by-step explanation:

The mean is 111.9 given that (105 + 113 + 122 + 121 + 116 + 118 + 107 + 93)/8 = 111.875 which can be rounded to 111.9 F.

Organizing the values we have:

[93, 105, 107, 113, 116, 118, 121, 122]

We find that the median is going to be between 113 and 116. Therefore:

(113 + 116) / 2 = 114,5

Therefore, the correct answer is option C.
