Answer:
The probability is 28 % ( approx )
Step-by-step explanation:
Since, there are only two possible outcomes in every trails ( residents are in their forties or not ),
So, this is a binomial distribution,
Binomial distribution formula,
Probability of success in x trials,
Where, 
p and q are probability of success and failure respectively and n is the total number of trials.
Let X be the event of resident who are in his or her forties.
Here, p = 12% = 0.12,
⇒ q = 1 - p = 1 - 0.12 = 0.88,
n = 9,
Hence, the probability that two or three of the people in the group are in their forties = P(X=2) + P(X=3)
Answer: 818.4
Step-by-step explanation:
Using the area of a sector formula, we get the area of the entire sector is 
.
Using the formula 
, we get the area of the triangle is 
.
So, the area of the shaded sector is

I believe the missing number is 65
Step-by-step explanation:
The Linear inequality holds true for 21 ≥ x;
What is Linear Inequality?
The mathematical expression with unequal sides is known as inequality in mathematics. Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. In this instance, any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to a symbol (), less than or equal to a symbol (), or not equal to a symbol (), is used in place of the equal sign "=" in the expression. Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics. The symbols "" and ">" signify tight inequalities, while "" and "" signify slack inequalities.
In the given question, the given inequality given is:
-3(2x-11) ≥ 8x-9;
Solving the Inequality:
⇒-6x + 33 ≥ 8x - 9;
⇒33 + 9 ≥ 8x - 6x;
⇒ 42 ≥ 2x;
⇒ 21 ≥ x;
Hence,
The Linear inequality holds true for 21 ≥ x;
