What is the recursive for 2, 8, 14, 20
Answers
Answer:
It's linear and it stays constant with every number it increases by 6 you will notice that almost immediately therefore making this simplistic and unworthy of my time no offense I'm only here for the points.
Step-by-step explanation: I hope this helps!
The recursive formula is \(a_n\\\) = 6n - 4.
What is Recursive formula?Any term of a series can be defined by its preceding term in a recursive formula (s).
A recursive formula consists of two parts: a declaration of the first term and a declaration of the formula connecting the succeeding terms.
For example: The recursive formula of an arithmetic sequence is,
an = an-1 + d.
Given:
2, 8, 14, 20
The above data shows Arithmetic Progression series.
a = 2
d = 8-2
d= 6
So, using Arithmetic Progression
\(a_n\) = a+ (n- 1) d
\(a_n\\\) = 2+ (n- 1)6
\(a_n\\\) = 2+ 6n - 6
\(a_n\\\) = 6n - 4
Hence, the recursive formula is \(a_n\\\) = 6n - 4.

Answers
The length of the displaced threshold for runway 22 at Toledo (TDZ) is 380 feet. Option C) is correct.
What is displaced threshold?A displaced threshοld is a designated pοrtiοn οf a runway where the starting pοint fοr landing aircraft is mοved further dοwn the runway. It is typically marked by white arrοws οr οther markings οn the pavement. The purpοse οf a displaced threshοld is tο create a clear area fοr οbstacles, such as buildings οr terrain, at the beginning οf the runway, allοwing aircraft tο apprοach the runway at a safer pοint.
This can be necessary due tο the presence οf οbstructiοns οr tο meet certain οperatiοnal requirements. When a displaced threshοld is present, the pοrtiοn οf the runway befοre the threshοld is nοt available fοr landing and takeοff οperatiοns.
Displaced threshold is half of clearance,
Therefore, we calculate the clearance and divide it by 2
(1000 - 620) / 2 = 380

Scenario 1B:
Remaining amount for Insurance and patient to pay is $350
Coinsurance amount is $70
Total paid by patient is $170
Medicare payment is $280
Provider write-off is $370
Scenario 1A:
Submitted charge: $650
Medicare participating physician fee schedule (PFS): $450
Coinsurance amount (20% paid by patient): $
Medicare payment (80% of the PFS): $
Provider write-off: $
To calculate the missing amounts, we can use the provided information:
Coinsurance amount (20% paid by patient):
Coinsurance amount = 20% of the Medicare participating physician fee schedule (PFS)
Coinsurance amount = 0.2 * $450 = $90
Medicare payment (80% of the PFS):
Medicare payment = 80% of the Medicare participating physician fee schedule (PFS)
Medicare payment = 0.8 * $450 = $360
Provider write-off:
Provider write-off = Submitted charge - Medicare payment
Provider write-off = $650 - $360 = $290
Scenario 1B:
Submitted charge: $650
Medicare participating physician fee schedule (PFS): $450
Patient pays $100 remaining on their deductible

To calculate the missing amounts, we can use the provided information:
Remaining amount for Insurance and patient to pay:
Remaining amount for Insurance and patient to pay = PFS - remaining deductible
Remaining amount for Insurance and patient to pay = $450 - $100 = $350
Coinsurance amount (20% of remaining amount):
Coinsurance amount = 20% of the remaining amount
Coinsurance amount = 0.2 * $350 = $70
Total paid by patient (deductible & 20% of remaining):
Total paid by patient = remaining deductible + coinsurance amount
Total paid by patient = $100 + $70 = $170
Medicare payment (80% of the remaining amount):
Medicare payment = 80% of the remaining amount
Medicare payment = 0.8 * $350 = $280

the half life of radium is 1690 years if 8 grams are present now how many grams will be present in 100 years
Answers
So, approximately 7.71 grams of radium will be present after 100 years.
To calculate the remaining amount of radium after 100 years, we will use the half-life formula:
Remaining Amount = Initial Amount * (1/2)^(time passed / half-life)
Here, the initial amount is 8 grams, the half-life is 1690 years, and the time passed is 100 years.
Step 1: Plug in the values
Remaining Amount = 8 * (1/2)^(100 / 1690)
Step 2: Calculate the exponent
Exponent = 100 / 1690 ≈ 0.05917
Step 3: Calculate the base raised to the exponent
(1/2)^0.05917 ≈ 0.9634
Step 4: Multiply the initial amount by the base raised to the exponent
Remaining Amount = 8 * 0.9634 ≈ 7.7072
So, approximately 7.71 grams of radium will be present after 100 years.

Answer:
66⁰ + x = 111⁰
x = 111⁰ - 66⁰
x = 45⁰
Answer:
First, I am taking the interior angle E as 'y' to be able to use the angle sum property to find 'x'.
So we can find 'y' by using 'linear pair'.
So Exterior angle 'E'+y=180 Degree.
= 111+y=180
By transposing: y=180-11
And y= 69 degrees.
And now have angles y & 'Angle G' we can use Angle sum property to find 'x'
ACCORDING TO ANFLE SUM PROPERTY OF TRIANGLE: "THE SUM OF ALL THE ANGLES OF A TRIANGLE IS 180 DEGREE"THEREFOR, y+x+angle G=180 degrees.
= 69 degrees+66 degrees+x=180 degrees
= 135 degrees+x=180 degrees
by transposing,
x= 180 degrees-135 degrees
And, x= 45 degrees
ANOTHER METHOD:BY USING EXTERIOR ANGLE PROPERTY.
ACCORDING TO EXTERIOR ANGLE PROPERTY OF TRIANGLE: "An exterior angle of a triangle is equal to the sum of its interior opposite angles"
So, Exterior Angle E= x+ Angle G
= 111 degrees= x+ 66 degrees
By transposing, x= 111 degrees-66 degrees
= x=45 degrees.
So no matter whichever method is used, the value of x= 45 degrees.

The visitor data is best modeled by a quadratic function, and the state park management should plan for more than 400 visitors next year.
How to determine the model of the function?To do this, we simply plot the points on a graph.
See attachment for the graph that represents the table.
From the attached graph, we can see that the points on the graph follows an approximately quadratic path
Hence, the visitor data is best modeled by a quadratic function
Also, the state park management should plan for more than 400 visitors next year.
This is so because the range of a quadratic function is the set of all real numbers.
This means that the table can accept a value of 400 (or greater) as one of its data points

They are the same because the probabilities of the x-values skew the values of the mean. If the probabilities were equal, the histograms would be different.
Answers
Option B- They are the same because, in this case, the means and medians are the same values is the correct answer.
It is specified that the means and medians are the same values. This suggests that the histograms of the two distributions have the same central tendency and are not impacted by the probabilities of the x-values. Hence, the means and medians will rise in this situation.
In statistics, the mean and median are measures of central tendency utilized to portray the normal or normal value of a dataset. Whereas they both give profitable data around the dataset, they can in some cases vary depending on the shape and distribution of the information.
Within the given situation, it is expressed that the means and medians are the same values. This suggests that the dataset incorporates a symmetric distribution with no skewness. When the distribution is symmetric, the mean and median will coincide, demonstrating that the information focuses are equally distributed around the centre.

Container I currently contain 4.6 gallons of water and is being filled at a rate of 1.2 gallons per minute. Container II currently has 54.6 gallons of water and is being drained at a rate of 0.8 gallons per minute. After how many minutes will both containers have the same amount of water?
Answers
Answer: After 25 minutes both containers will have the same amount of water.
Step-by-step explanation:
Let x = Number of minutes
y= Quantity of water
For container I, Quantity of water will be :
y = 4.6+ 1.2x
For container II, Quantity of water will be :
y = 54.6-0.8x
According to the question, we have
4.6+ 1.2x = 54.6-0.8x
Add 0.8x on both sides and subtract 4.6 on both sides , we get
1.2x+8x = 54.6-4.6
⇒ 2x = 50
Divide both sides by 2, we get
x= 25
So after 25 minutes both containers will have the same amount of water.

So this pattern is linear, that means the "rule" you are looking for does not have exponents or square roots or any very complicated stuff. You can use a guess and check method. Say to yourself how can I get a 7 out, when I put a 3 in? "times by2 and plus 1" works.

2(-1)+1 = -1
2(0)+1 = 1
2(1)+1 = 3
2(2)+1 = 5
It works for all the numbers.
You can calculate it also, using any two pairs of (x,y) from the data set. Put y-y on top of a fraction and x-x on the bottom. You will get the slope and that is the 2 in the "rule"
(3,7) and (2,5) for example. 7-5 so put 2 on top and 3-2 so put 1 on the bottom. 2/1 is just 2. From the point (0,1) we know the y-intercept is 1. This also gives the equation y=2x+1.
If you are just starting to learn this, probably just guess and check a rule. The rule has to work for all the points.

Answers
The number will be less than 1 because when adding the exponents, 11 (negative 14) result the negative 3, and a number in scientific notation with a negative exponent is less than 1.
Thus the option 4 is the correct option.
What is the exponent power with base 10?
To write the big number in short form, we write them in the positive power of 10.
To write the very small number, we write them in the negative power of 10.
Given information-
The number whose value Bethany wants to estimate is,
\((4.296\times10^{11})(1.8614\times10^{-14})\)
Here the power of the 10 is 11 and -14 for the two number.
First solve the number without the multiple of 10 or the power of 10 is zero as,
\((4.296\times1.8614)(10^{11}\times10^{-14})\\8\times(10^{11}\times10^{-14})\)
The power of the two numbers with same base is added in the multiplication. thus,
\(8\times(10^{11-14})\)
Solve it further,
\(8\times(10^{-3})\)
Thus,
The number will be less than 1 because when adding the exponents, 11 (negative 14) result the negative 3, and a number in scientific notation with a negative exponent is less than 1.
Thus the option 4 is the correct option.

the mean composite score for seniors who took the sat in 2018 was 1068. if the standard deviation for this same year was 180, what is the raw score for a person with a z score of –0.42?
Answers
A person with a Z-score of -0.42 would have a raw score of 992.4 on the SAT taken in 2018.
The standard deviation is a measure of how much the data varies from the mean. A Z-score is a standardized value that represents the number of standard deviations a raw score is from the mean.
To find the raw score given a Z-score, we can use the following formula:
raw score = mean + Z-score * standard deviation
For the mean composite score of 1068 and a standard deviation of 180, we can plug in the values for the Z-score of -0.42:
raw score = 1068 + (-0.42) * 180
raw score = 1068 - 75.6
raw score = 992.4
