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.

Answer:
Step-by-step explanation:
Let us say that:
K = age of Kristen
B = age of Ben
From the problem, we make the equations:
eqtn 1: K + B = 32
eqtn 2: (K – 4) = 2 (B – 4)
Simplifying eqtn 2:
K – 4 = 2 B – 8
K = 2 B – 4
Plugging in this to eqtn 2:
(2 B – 4) + B = 32
3 B – 4 = 32
3 B = 36
B = 12
From eqtn 2:
K = 2 B – 4 = 2 (12) – 4 = 20
So Kristen is 20 while Ben is 12.
Answer:
0.35
Step-by-step explanation:
This probability distribution is shown below:
Pitch 1 2 3 4 5
Frequency 15 20 40 15 10
Probability 0.15 0.2 0.4 0.15 0.1
The probability that the pitcher will throw fewer than 3 pitches to a batter = P(X < 3)
X is the number of pitches thrown. Therefore:
P(X < 3) = P(X = 1) or P(X = 2)
The additive rule pf probability states that if two events X and Y are dependent events, the probability of X or Y occurring is the sum of their individual probability.
P(X < 3) = P(X = 1) or P(X = 2) = P(X = 1) + P(X = 2) = 0.15 + 0.2 = 0.35
The probability that the pitcher will throw fewer than 3 pitches to a batter = 0.35
