The first two numbers in a sequence h are h(1)=2 and h(2)=6
If h is an arithmetic sequence, write a definition for the nth term of h explain or show your reasoning.
Answers
An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference. The nth term of the arithmetic series can be defined as hₙ = 4n - 2.
What is an arithmetic sequence?An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.
If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:
a, a + d, a + 2d, ... , a + (n+1)d, ...
The nth term of an arithmetic sequence is given by the formula,
aₙ = a₁ + (n-1)d
Since the first term of the arithmetic sequence is 2, while the difference is 4. Therefore, the definition for the nth term of arithmetic sequence,h can be written as,
hₙ = 2 + (n-1)4
hₙ = 2 + 4n -4
hₙ = 4n - 2
Hence, the nth term of the arithmetic series can be defined as hₙ = 4n - 2.

Calculating Binomial Probabilities - Suppose you work for an airline and you are taking reservations for a flight on an aircraft that has 152 seats. You know, based on historical flights trends, that if you sell a single ticket there is a 91% chance that the person with the ticket will actually show up for the flight. You decide to try to make a little extra money by overbooking your flight and you sell 160 tickets hoping that not more than 152 people will actually show up for the flight (note: this is a common business practice! Click here to watch a video that explains why)
Explain how this scenario meets the four requirements in the definition of a Binomial Distribution.
Identify what n and p are in this example
Use technology (StatCrunch, Statdisk, or Excel) to calculate the probability that if you sell 160 tickets for your flight, more passengers will show up than there are seats available (again, the plane has 152 seats total). Post an image of your technology output using the Insert/Edit Image feature in Blackboard (no attachments!)
Based on this probability, do you think it is a wise business practice to oversell your flight in this manner? Explain.
Answers
The probability that if you sell 160 tickets for your flight, more passengers will show up than there are seats available is 0.02
How the scenario meet the requirements?The scenario meets the following requirements
The value of n is fixed i.e. 160The outcome has two possible values i.e. seats available or notThe chance that a person shows up is the same for each outcome i.e. p = 91%Each observation is independent.Identify n and pThe given parameters are:
n = 160
p = 0.91 i.e. 91%
x = 152
How to determine the probability?The distribution is a binomial distribution, and it is calculated using:
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n -x}[/tex]
The probability is represented as:
P(x > 152) = P(153) + ..... P(160)
Using a technology tool, we have:
P(x ≤ 152) = 0.02
Conclusion on the calculationProbability values less than 0.25 are unlikely probabilities.
Because the probability value 0.02 is less than 0.25, then we can conclude that it is a wise business practice to oversell your flight in this manner.

Find x and y.
Answers
(3y + 40) + (130 -2x) = 180 because the angles are supplementary
plug in x
3y + 40 + 130 - 2(65/3) = 180
so 3y = 95/3
therefore y = 95/6
x = -25
y = -13.33
Step-by-step explanation
To find x
(130 - 2x)° + 4x° = 180°
130 - 2x + 4x = 180
130 - 2x = 180
130 - 180 = 2x
x = -50 ÷ 2
x = -25 answer
To find y
(130 - 2x)° + (3y + 40)° = 180°
130 - 2x + 3y + 40 = 180
170 - 2x + 3y = 180
By putting the vaue of x in the equation
170 - 2(-25) + 3y = 180
170 + 50 + 3y = 180
3y = 180 - 170 - 50
y = -40 ÷ 3
y = -13.33 answer

- If five is subtracted from a number, the result is two.
- Five less a number is equal to two.
please send help :')
Answers
Answer:
Answer would be B
Step-by-step explanation:
First, A doesnt make sense, since it isn't a ineqality.
C doesnt make sense because if 5 is subtracted form a number n, it is -2, not 2.
D doesnt work because 5 less a number (-5) is not 2, it is -2.
So B works, because the difference between n and 5 (n-5) is -2.

What is the median?A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

As we know, the range = Max value—Min value
Here, Max = $2.42
Min = $2.03
Range = 2.42 - 2.03 = $0.39
Thus, the range is $0.39 which is the difference of the max value and min value.
