In mathematics, a sequence is an ordered list of elements, often denoted by brackets or parentheses.
What the meaning of "a sequence of length n"?The term "a sequence of length n" refers to a sequence that contains a specific number of elements, where the number of elements is denoted by "n."
When the domain of a function is the set of natural numbers (N), it is called an infinite sequence. An infinite sequence can be thought of as an ordered list that continues indefinitely.

x-y=3. 2x-3y=4
Answers
Answer:
x - y = 3
2x - 3y = 4
Igualación
Despejamos una de las incógnitas en cada ecuación e igualamos. (En este caso la x)
3y + 4
x = y + 3 x = ---------------
2
3y + 4
y + 3 = ---------------
2
2 (y + 3 ) = 3y + 4
2y + 6 = 3y + 4
se pasan las incógnitas a un lado y lo que cambia de lado se cambia de signo
3y - 2y = 6 - 4 ⇒ y = 2
sustituimos el valor de y en cualquiera de las dos para obtener el valor de x
x - 2 = 3 ⇒ x = 5
Solución
x = 5
y =2

Is the line through points P(3, -5) and Q(1, 4) parallel to the line through points R(-1, 1) and S(3, -3)? Explain.
Answers
Given parameters:
Coordinate of line 1 = P(3, -5) and Q(1, 4)
Coordinate of line 2 = R(-1, 1) and S(3, -3)
To know if the two lines are parallel, it must hold that both lines must have the same amount of slope.
Parallel lines are lines that do no intersect at any point.
So we must find the slope of the both lines given.
The formula of the slope of line is:
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
For line 1, P(3, -5) and Q(1, 4) and line 2 R(-1, 1) and S(3, -3)
x₁ = 3, y₁ = -5
x₂ = 1, y₂ = 4
So;
Slope of line 1 = [tex]\frac{4-(-5)}{1-3}[/tex] = [tex]\frac{-9}{2}[/tex]
For line 2 R(-1, 1) and S(3, -3)
x₁ = -1, y₁ = 1
x₂ = 3, y₂ = -3
Slope of line 2 = [tex]\frac{-3-1}{3-(-1)}[/tex] = [tex]\frac{-4}{4}[/tex] = -1
Since both slopes are different, they are not parallel lines. Parallel lines have the same slope.

A goodness of fit test will be conducted for the following hypotheses. This type of test is always an upper tail test. The p-value approach will be used, meaning that the given level of significance, α = 0.01, will be compared to the area under the curve to the right of the calculated test statistic.
H0 : pA = 0.40, pB = 0.40, and pC = 0.20
Ha : The population proportions are not pA = 0.40, pB = 0.40, and pC = 0.20.
The goal of the hypothesis test is to determine if the observed proportions are significantly different from the given proportions. A sample size of 200 yielded 20 in category A, 100 in category B, and 80 in category C. Assuming the hypothesized proportions are true, then the expected frequencies in each category will be the product of the hypothesized proportions and the sample size.
expected frequency = category proportion(sample size)
The proportion for category A is assumed to be 0.40. Use the sample size of 200 to find the expected frequency for this category, eA.
expected frequency = category proportion(sample size)
eA = ( _____ ) (200)
The proportion for category B is assumed to be 0.40. Use the sample size of 200 to find the expected frequency for this category, eB
expected frequency = category proportion(sample size)
eB = ( ______ ) (200)
The proportion for category C is assumed to be 0.20. Use the sample size of 200 to find the expected frequency for this category, ec expected frequency = category proportion(sample size)
eC = ( ______ )(200)
Answers
Answer:
1. 80
2. 80
3. 40
Step-by-step explanation:
The question requires us to Use the sample size of 200 to find the expected frequency for categories A, B and C
1. (Category proportion)(sample size)
eA = 0.40x200
= 80
2. (Category proportion)(sample size)
eB = 0.40x200
= 80
3. (Category proportion)(sample size)
eC = 0.20 x 200
= 40
The answers are 80, 80 and 40 respectively.
28. Kay is saving $200 a month into an account earning 5% interest. How long will it
take her to save $20,000?
Answers
Step-by-step explanation:
Accumulated value = $20,000.
A = P + I, P = principal, I = Interest.
I = 200*5*t/100
I = 1000t/100 = 10t
2000 = P + I = 200 + 10t
2000 - 200 = 10t
1800 = 10t, t = 180.
Therefore, it would take her 180 years to save $20,000.

The temperature unit of Kelvin is used to determine the absolute temperature scale. such as “absolute zero" or “infinite cold." The formula to convert Fahrenheit to Kelvin can be expressed as K = 5/9(F - 32) + 273. where K is the degrees in Kelvin and F is the temperature in Fahrenheit.
Rearrange the formula to find the temperature of Fahrenheit in terms of Kelvin.
Solve for F, keeping the answer in fraction form
Answers
Answer:
[tex]F = 32 + \frac{9}{5}(K - 273)[/tex]
Step-by-step explanation:
Given
[tex]K = \frac{5}{9}(F - 32) + 273[/tex]
Required
Solve for F
[tex]K = \frac{5}{9}(F - 32) + 273[/tex]
Subtract 273 from both sides
[tex]K - 273= \frac{5}{9}(F - 32) + 273 - 273[/tex]
[tex]K - 273= \frac{5}{9}(F - 32)[/tex]
Multiply through by [tex]\frac{9}{5}[/tex]
[tex]\frac{9}{5} *(K - 273)= \frac{9}{5} * \frac{5}{9}(F - 32)[/tex]
[tex]\frac{9}{5}(K - 273)= F - 32[/tex]
Add 32 to both sides
[tex]32 + \frac{9}{5}(K - 273)= F - 32 + 32[/tex]
[tex]32 + \frac{9}{5}(K - 273)= F[/tex]
[tex]F = 32 + \frac{9}{5}(K - 273)[/tex]
The cost of printing T-shirts is defined by the equation C = 250+5.5n, where C represents the total
cost and I represents the number of T-shirts. If the school paid $965.00, how many T-shirts were
printed?
Answers
Answer:
The school paid for printing 130 T-shirts
Step-by-step explanation:
Function Models
We are given the cost of printing n T-shirts as the equation:
[tex]C=250+5.5n[/tex]
For example, if 10 T-shirts were printed, the school would pay:
[tex]C=250+5.5(10)=250+55=\$305[/tex]
We know the school paid $965 and are required to find the number of T-shirts that were printed. If we use the equation with C=965, we can solve it for n:
[tex]965=250+5.5n[/tex]
[tex]965-250=5.5n \Rightarrow 5.5n=715[/tex]
Solving:
[tex]n=715/5.5=130[/tex]
The school paid for printing 130 T-shirts

If Jay runs for 20 minutes and burns 112 calories. How many calories will he burn if he ran for 45 minutes? Pls help me Imao im dying inside ;_;
Answers
Jay burns 252 calories in 45 minutes
Step-by-step explanation:
This is proportions so put 20/45 represents minutes and 112/x represents calories. Jay runs 20 minutes and burns 112 calories. so if Jay runs for 45 minutes so he burns 252. so x=252
20/45 112/x multiply 45 and 112 and then divide 20 and you get an answer of 252. To double check if you got the right answer you multiply 20 and 252 and you get the same answer as 45 x 112
I know this because I am learning about proportions so it is simple to me to answer.
Find (9.3 × 106) + (1.8 × 104). Express your answer in scientific notation.
Answers
Answer:
(9.3 × 106) + (1.8 × 104) =
985.8 + 187.2 =
1173
Step-by-step explanation:
The required scientific notation of (9.3 × 10^6) + (1.8 × 10^4) is 93.18E+5.
To find (9.3 × 106) + (1.8 × 104) and express the answer in scientific notation.
An expression in the form of abE+5 is scientific notation.
To Write the expression in the scientific notation, for example, 12.34 * 10^6
First, put the non-zero digit with desired decimal points in order to show a more simple value, and Put E after the digit and add + and - sign after it which shows the 10 exponents of the digit positive or negative. Then put the value of the exponent. eg 12.34E+6.
⇒(9.3 × 106) + (1.8 × 10^4)
⇒ (9.3 × 106) + (0.018 × 10^6)
⇒ (9.3 + 0.018)× 10^6
⇒ (9.318)× 10^6
For scientific notation
=93.18E+5
Thus, the required scientific notation of (9.3 × 10^6) + (1.8 × 10^4) is 93.18E+5.
