The number of ways 5 suspects can be selected from 9 by the police is 126.
The number of ways the police can select 5 suspects from 9 is calculated using combinations. In this case, it is a combination problem because the order in which the suspects are selected does not matter. The formula for combinations is:
C(n, k) = n! / (k! * (n - k)!)
where n is the total number of suspects and k is the number of suspects to be selected.
Therefore, substituting n = 9 and k = 5 into the formula:
C(9, 5) = 9! / (5! * (9 - 5)!)
C(9, 5) = 126 ways

find four consecutive even integers such that 2 times the sum of the first and second is 14 more than 3 times the fourth.
The required four consecutive even integers are given as 28, 30, 32, and 34.
Given that,
Four consecutive even integers such that 2 times the sum of the first and second is 14 more than 3 times the fourth.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let, the first term be a, and the common difference be d,
And series 2n, 2n + 2, 2n +4, 2n + 6
According to the question,
2[2n + 2n + 2] = 14 + 3[2n + 6]
8n + 4 = 14 + 6n + 18
2n = 28
n = 14
Series can be given as,
28, 30, 32, 34
Thus, the required four consecutive even integers are given as 28, 30, 32, and 34.

Mitch refuses to dine at a certain restaurant because he recalls reading two or three negative reviews of its service on a popular website. Mitch is falling prey to:
In this situation, we can actually see that Mitch was simply basing her taste on the information that is readily available to her. She does not even consider whether those reviews are legit or reliable. Mitch is falling into what we call as:
“the availability heuristic”
Mitch is falling prey to the bandwagon effect, where he avoids dining at a restaurant based on a few negative reviews he read online. The bandwagon effect is a cognitive bias that leads us to adopt beliefs or behaviors because we think everyone else is doing the same.
Explanation:Mitch is falling prey to the bandwagon effect. The bandwagon effect is when someone adopts a certain belief or behavior because they believe that everyone else is doing it too. In this case, Mitch refuses to dine at a certain restaurant because of negative reviews he read on a popular website, assuming that those reviews reflect the majority opinion.
The bandwagon effect is a cognitive bias that can influence our decision-making process. It is important to be aware of this bias and make decisions based on objective information rather than simply following the crowd.

The new shanghai restaurant offers a choice of five appetizers, two choices of soups, and eleven choices of entrees for its lunch special. how many different complete lunches can be ordered from the restaurant's lunch special menu?
Final answer:
Using the Multiplication Principle, a customer can choose from 110 different complete lunch combinations by selecting one of each option (appetizer, soup, and entrée) from the menu at the New Shanghai restaurant.
Explanation:
To determine the total number of different complete lunches that can be ordered from the restaurant's lunch special menu, we apply The Multiplication Principle of counting. The principle states that if one event can occur in m ways and another independent event can occur in n ways, then the total number of ways both events can occur together is the product of m and n. In the context of ordering a lunch, each choice (appetizer, soup, and entrée) represents an independent event.
For appetizers, there are 5 choices.
For soups, there are 2 choices.
For entrées, there are 11 choices.
Following the Multiplication Principle, the total number of different complete lunches is calculated as follows:
5 appetizers × 2 soups × 11 entrées = 110 different complete lunches.
Therefore, customers have the opportunity to choose from 110 unique complete lunch combinations at the New Shanghai restaurant.

How long is the minute hand on a clock whose tip travels 15 cm from 1:15 to 1:30 to the nearest tenth?
Answer:
The length of minute hand is 9.5 cm
Step-by-step explanation:
We are given the minute hand move from 1:15 to 1:30
Time for 1:30 to 1:30 = 15 minutes
Tip of minute hand move 15 cm in 15 minutes.
In 60 minutes = 360°
In 1 minute = 6°
In 15 minutes = 90°
Formula: [tex]\theta=\dfrac{L}{r}[/tex]
[tex]\theta=90^\circ[/tex]
Now we change [tex]\theta=90^\circ[/tex] into radian
[tex]Radian=\dfrac{\pi}{180^\circ}\times 90^\circ=\dfrac{\pi}{2}[/tex]
L=15 cm
R = Length of minute hand.
[tex]\dfrac{\pi}{2}=\dfrac{15}{R}[/tex]
[tex]R=\dfrac{30}{\pi}\approx 9.5[/tex]
Hence, The length of minute hand is 9.5 cm
Which algebraic expression is a polynomial with a degree of 2?
a)4x3 − 2x
b10x2 −
c)8x3+ + 3
d)6x2 − 6x + 5
Answer:
D) 6x² − 6x + 5 has degree 2.
Step-by-step explanation:
Given : Polynomial .
To find : Which algebraic expression is a polynomial with a degree of 2.
Solution: We have given polynomial
Degree : The highest power of the polynomial is called degree.
We can see from the given polynomials two polynomial have 2 power
first is [tex]10x^{2} -\sqrt{x}[/tex].
Second is 6x² − 6x + 5.
But the first term have root so, it is not a polynomial.
So 6x² − 6x + 5 has degree 2
Therefore, D) 6x² − 6x + 5 has degree 2.
