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.

Rashid [163]

Answer:

19.55\pm2.145

Step-by-step explanation:

We use the equation \bar x\pm z^*\sigma/\sqrt n, where \bar x=19.55, \sigma=6.33, n=41, and z^*=2.17. We obtain z^* from the z-score of a 0.97 confidence level.

m_a_m_a [10]

Answer:

6.25%

Step-by-step explanation:

Total = 1 ; as a decimal

1/2 = skittles

1/4 = M&Ms

Skittles +M&Ms = 1/2 + 1/4 = 3/4

Remainder = 1 - \frac{3}{4}

Remainder = \frac{1}{4}

Sour patch = \frac{1}{4} *\frac{1}{4} =\frac{1}{16}

As a percentage , multiply 1/16 by 100 and it becomes 6.25%
