We are given a sequence of five non-zero numbers, where the sum of each term and its neighboring terms is 15 or 25. Find the sum of all the terms in the sequence.
We have a sequence that meets the given criteria, and with that information, we want to get the sum of all the terms in the sequence.
We will see that the sum tends to infinity.
So we have 5 terms;
A, B, C, D, E.
We know that the sum of each term and its neighboring terms is 15 or 25.
then:
A + B + C = 15 or 25B + C + D = 15 or 25C + D + E = 15 or 25Now, we want to find the sum of all the terms in the sequence (not only the 5 given).
Then let's assume we write the sum of infinite terms as:
[tex]a_1 + a_2 + a_3 + a_4 + a_5 + a_6 + ...[/tex]
Now we group that sum in pairs of 3 consecutive terms, so we get:
[tex](a_1 + a_2 + a_3) + (a_4 + a_5 + a_6) + ...[/tex]
So we will have a sum of infinite of these, and each one of these is equal to 15 or 25 (both positive numbers). So when we sum that infinite times (even if we always have the smaller number, 15) the sum will tend to be infinite.
Then we have:
[tex](a_1 + a_2 + a_3) + (a_4 + a_5 + a_6) + ... \to \infty[/tex]

The family purchased refreshments and spent a total of $18.50. If the total amount of money spent
on tickets and refreshments was $94.50, use an equation to find the cost of one regular admission
ticket.
How would you write the equation?
(94.50 - 18.50) ÷ f = a
f=family members

What is the slope of the line?
3(y- 1) = 2x + 2
Answer:
2/3
Step-by-step explanation:
1. The easiest way to find the slope of the line is by converting this equation into slope-intercept form (y = mx + b).
y = y-coordinatem = slopex = x-coordinateb = y-intercept2. (Solving)
Step 1: Simplify both sides of the equation.
[tex](3)(y) + (3)(-1) = 2x + 2[/tex] [tex]3y - 3 = 2x + 2[/tex]Step 2: Add 3 to both sides.
[tex]3y - 3 + 3 = 2x + 2 + 3[/tex] [tex]3y = 2x + 5[/tex]Step 3: Divide both sides by 3.
[tex]\frac{3y}{3} = \frac{2x+5}{3}[/tex] [tex]y = \frac{2}{3}x + \frac{5}{3}[/tex]3. Since 2/3 is in place of m, the slope, the slope of the line is 2/3.

You mowed 2.25 yards in 1.5 hours. How many yards did you mow in 1 hour?
Answer:
1.5
Step-by-step explanation:
to find one hour you divide both answers by 1.5 giving you one hour and 1.5
1.5 yards did you mow in 1 hour when, You mowed 2.25 yards in 1.5 hours.
What is division?Division is the process of splitting a number or an amount into equal parts.
Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
You mowed 2.25 yards in 1.5 hours.
in 1 hours I mowed = 2.25/1.5

Which equation demonstrates the additive identity property?
0 (7+4i)+(7-4i) = 14
O (7+4i)+ 1 = 7+4i
(7+4)(1) = 7+4)
O (7+4i)+(-7-4i)= 0
Answer:
A
Step-by-step explanation:
The Explication 0 (7+4i)+(7-4i) = 14
The correct equation which demonstrates the additive identity property is,
⇒ (7 + 4i) + 0 = 7 + 4i
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Now, If we add a real number to zero or add zero to a real number, then we get the same real number back.
Hence, The number zero is known as the identity element, or the additive identity.
For example: a + 0 = a
Hence, we can see that;
⇒ (7 + 4i) + 0 = 7 + 4i
Since, 0 is the additive identity here.
Thus, The correct equation which demonstrates the additive identity property is,
⇒ (7 + 4i) + 0 = 7 + 4i

Answer:
69.9 (nice)
Step-by-step explanation:
To solve this, use the order of operations: PEMDAS (Parenthasis, exponents, Multiplication/Division, Addition/subtraction) In order.
1. Solve in the parenthasis, (2+3³). 3³ = 27, so 2+27 is 29. Plug in 29 to the equation: 5³-29×1.9
2. Next is exponents. 5³ has an exponent, which equals 125. Now you plug that into the equation to be 125-29×1.9
3. Now comes multiplication/division. In this case, it's multiplication. -29×1.9 . This equals -55.1, and you once again plug this into the equation to simplify which gives you 125 - 55.1
4. Last in the order of PEMDAS is addition/subtraction. The final simplification of the equation is 125 - 55.1 which is subtraction and this equals 69.9 (nice)
So in conclusion, your answer is 69.9 (nice)

1) (1,9) ; slope = 2
Point slope form:
y - y₁ = m(x - x₁)
y - 9 = 2(x - 1)
Slope intercept form:
y - 9 = 2x - 2
y = 2x - 2 + 9
y = 2x + 7
3) (-4 , -5) ; slope = 3/5
Point slope form:
y - y₁ = m(x - x₁)
[tex]y - [-5] = \dfrac{3}{4}(x - [-4])\\\\\\y + 5 = \dfrac{3}{4}(x + 4)[/tex]
Slope intercept form:
[tex]y + 5 = \dfrac{3}{4}x + 4*\dfrac{3}{4}\\\\y + 5 =\dfrac{3}{4}x + 3\\\\y = \dfrac{3}{4}x +3 -5 \\\\\\y = \dfrac{3}{4}x - 2[/tex]

You are recently promoted as the chief traffic management officer of a major city in the country. Based on recent data, you learned that one of the leading causes of road accidents is over speeding.
In your desire to minimize road accidents, you went out to observe how traffic management rules are implemented on the streets. Your attention was caught by a fast - moving car that seemed to be breaking the speed limit of 100 kilometers per hour(km/hr.), and so you followed it along the highway. After a short time, the driver of the car noticed you and started to slow down. Eventually, he stopped on the side of the road.
Supposed the speed of the car had been noted during this time and is modeled by the quadratic equation y = 3x² + 17x - 20, where y represents the speed of the car in km/hr. and x represents the number of minutes after you started following the car. How long did it take for the car to be under surveillance before it could finally stop on the side of the road? Did the driver of the car really break the speed limit of 100 km/hr.? Explain. The result of your observation will be presented to the students in your section and will be graded by your teacher.

what value of durbin–watson statistic indicates no autocorrelation is present?
Answer:
2
Step-by-step explanation:
when the value is below 2
a situation in which no identifiable relationship exists between the values of the error term.
The value of Durbin–Watsons statistic indicates no autocorrelation is present is 2.
What is Durbin–Watsons statistic?The output of a regression model is tested for autocorrelation using the Durbin-Watson statistic. Zero autocorrelation is indicated by a value of 2.0 in the DW statistic, which has a range of zero to four. Positive autocorrelation is indicated by values below 2.0, and negative autocorrelation is shown by values over 2.0.
As, The range of the Durbin-Watson statistic is 0–4. There is no first-order autocorrelation when the number is 2 or close to 2.
The range of 1.50 to 2.50 is suitable.
A number between 0 and 4 will always be assigned to the Durbin-Watson statistic.
A value of 2.0 means that no autocorrelation in the sample was found. Positive autocorrelation is shown by values between 0 and less than 2 whereas negative autocorrelation is indicated by values between 2 and 4.
