The function in option number C is a linear function.
Here, we are given 4 functions. Let us check them one by one to see if they are linear or not-
A. In this function, if x = 0, y =11
if x = 1, y = 7
Thus, if x increases by 1, y increases by 4.
but now if we see when x = 2, y = 5 which is not an increase of 4.
Thus, the given function is not linear.
B. In this function, if x = 0, y = 0
if x = 1, y = 0
Thus, if x increases by 1, y increases by 0.
but now if we see when x = 2, y = -1 which is not an increase of 0.
Thus, the given function is not linear.
C. In this function, if x = 0, y = 6
if x = 1, y = 12
Thus, if x increases by 1, y increases by 6.
when x = 2, y = 18 which is an increase of 6.
similarly, when x = 3, y = 24 which is an increase of 6.
Thus, the given function is linear.
Hence function in option number C is a linear function.

According to Euclidean geometry, how many lines can pass through a given pair of two distinct points?
GEOMETRIC : Only 1 straight line can pass through two distinct points simultaneously.
NONSENSICAL : Infinite lines can pass through two distinct points to be exact - (2*Infinite - 1)
Explanation.
Let the points be A and B
A can have infinite lines pass through it
B can have infinite lines pass through it
A & B together has one line pass through them
A+B = A + B - (A&B) = Inf + Inf - 1 = 2*Inf - 1 (Approx Inf).
According to Euclidean geometry two distinct points determine a unique straight line.
According to Euclidean geometry, two distinct points determine a unique straight line. This fundamental concept is known as the "line postulate" or the "two-point postulate." In Euclidean geometry, a straight line is the shortest path between two points, and it's determined by those two points.
To put it simply, given two distinct points, there is one and only one straight line that can pass through both of them. This is a foundational principle in Euclidean geometry and plays a crucial role in defining various geometric concepts and theorems.

Line q passes through points (10, 9) and (4, 2). Line r passes through points (8, 8) and (2, 1). Are line q and liner parallel or perpendicular?
Answer: Parallel
Step-by-step explanation:
To solve this question, we need to find the slopes of both lines q and r.
First, let's find the slope of line q.
Δx/Δy=-7/-6 = 7/6
Next, the slope of line r.
Δx/Δy=-7/-6 = 7/6
Both lines have the same slope.
Therefore, they are parallel.

Alaina has 7 in her bank account and earns 6 each day . joel has 48 in his banck account and earn 8 earch day in how many days will joel have as much money alaina
Answer:
I think you wrote something wrong.
Step-by-step explanation:
If Alaina has $7 in her bank account and Joel had $48 in his Joel already has more then Alaina but I will attempt to teach you how to solve these types of problems.
for this example I'm giving Alaina 79 dollars.
First we know were starting with 79 dollars and increasing 6 dollars each day so the equation for this is; y = 6x + 79 that is Alaina's equation.
For Joel our equation will be; y = 8x + 48.
Since they already have 79 and 48 dollars in their bank we put those as our B in the equation cause they are our y-intercepts. (Y = mx + b) Next we know their increasing by 6 and 8 dollars a day so we make those our m. Once we have these equations we can plot them and see where the lines meet. (thats our answer) I plotted them on desmos graphing calculator.
They crossed at (15.5, 172) Which means it will take 16 days for Joel to catch up they will both have 172 dollars in the bank account on the 16th day.

C.
The expected frequencies are variables, as they are determined by the sample size and the distribution in the alternative hypothesis.
D.
The expected frequencies are not variables, as they are determined by the sample size and the distribution in the null hypothesis.
The observed frequencies are variables as they vary from sample to sample. The expected frequencies are not variables as they are determined by the sample size and the distribution in the null hypothesis.
The observed frequencies are variables because they can vary from sample to sample.
In statistical analysis, observed frequencies represent the actual frequencies or counts of events or occurrences observed in a sample.
These frequencies are obtained through data collection and can differ between different samples due to random sampling variability.
Therefore, the observed frequencies are considered as variables that can change from one sample to another.
On the other hand, the expected frequencies are not variables. They are determined by the sample size and the distribution assumed in the null hypothesis.
Expected frequencies are the frequencies that would be expected under the assumption of a particular statistical model or hypothesis.
These frequencies are calculated based on the expected proportions or probabilities predicted by the null hypothesis and the sample size.
Once the sample size and the distribution in the null hypothesis are determined, the expected frequencies become fixed values and do not vary across different samples.
They provide a baseline against which the observed frequencies can be compared to assess the agreement between the observed data and the expected distribution.
In summary, the observed frequencies are considered variables as they vary from sample to sample, while the expected frequencies are not variables but are determined by the sample size and the distribution assumed in the null hypothesis.

Test 1 A 19.5% discount on a flat-screen TV amounts to $490. What is the list price? The list price is (Round to the nearest cent as needed.)
The list price of the flat-screen TV, rounded to the nearest cent, is approximately $608.70.
To find the list price of the flat-screen TV, we need to calculate the original price before the discount.
We are given that a 19.5% discount on the TV amounts to $490. This means the discounted price is $490 less than the original price.
To find the original price, we can set up the equation:
Original Price - Discount = Discounted Price
Let's substitute the given values into the equation:
Original Price - 19.5% of Original Price = $490
We can simplify the equation by converting the percentage to a decimal:
Original Price - 0.195 × Original Price = $490
Next, we can factor out the Original Price:
(1 - 0.195) × Original Price = $490
Simplifying further:
0.805 × Original Price = $490
To isolate the Original Price, we divide both sides of the equation by 0.805:
Original Price = $490 / 0.805
Calculating this, we find:
Original Price ≈ $608.70
Therefore, the list price of the flat-screen TV, rounded to the nearest cent, is approximately $608.70.

which of the following is a divergent series? the harmonic series a p-series with p=14 a p-series with p=π i only i only ii only ii only i and ii only i and ii only i, ii, and iii
The harmonic series and a p-series with p=14 are both divergent series. Therefore, the correct answer is (I) and (II).A series is said to be divergent if its terms do not approach a finite limit as the number of terms increases.
(I) The harmonic series is given by the sum of the reciprocals of positive integers: 1 + 1/2 + 1/3 + 1/4 + ... This series is well-known to be divergent, meaning that the sum of its terms becomes arbitrarily large as more terms are added.
(II) A p-series with p=14 is given by the sum of the reciprocals of the positive integers raised to the power of 14: 1/1^14 + 1/2^14 + 1/3^14 + ... Similar to the harmonic series, this series is also divergent. As the exponents are larger than 1, the terms decrease at a slower rate, leading to an infinite sum.
(III) A p-series with p=π is not provided, so we cannot determine its convergence or divergence. Based on the explanations above, the correct answer is (I) and (II) since the harmonic series and a p-series with p=14 are both divergent series.

Step-by-step explanation:
Recurrence: Expansion or Tree approach (Point 4) Solve the following recurrence, and prove that T(n)=Θ(n). (Need to mathematically explain all the steps) T(n)=T(n/2)+n, where n is a power of 2 . That means, let n=2k for integer k>0. You can only use expansion or tree approach. You can not use induction or master theorem here.
The solution to the recurrence relation T(n) = T(n/2) + n is T(n) = Θ(n).
To solve the given recurrence relation T(n) = T(n/2) + n, where n is a power of 2 (n = 2^k), we can use the expansion or tree approach.
Expanding the recurrence relation:
T(n) = T(n/2) + n
= T(n/4) + (n/2) + n
= T(n/8) + (n/4) + (n/2) + n
= T(n/2^k) + n/2^(k-1) + n/2^(k-2) + ... + n/2 + n
We can observe that the expansion continues until n/2^k = 1, which means k = log2(n). Therefore, the expansion becomes:
T(n) = T(1) + n/2^(k-1) + n/2^(k-2) + ... + n/2 + n
Now, let's simplify the expression by substituting k = log2(n):
T(n) = T(1) + n/2^(log2(n)-1) + n/2^(log2(n)-2) + ... + n/2 + n
Since n is a power of 2, we can rewrite the expression as:
T(n) = T(1) + n/2^(log2(n)-1) + n/2^(log2(n)-2) + ... + n/2 + n
= T(1) + n/2^(log2(n)) + n/2^(log2(n)-1) + ... + n/2 + n
We can see that the sum of the terms in the expression is a geometric series with a common ratio of 1/2. The sum of a geometric series can be calculated as:
S = a(1 - r^m) / (1 - r)
where a is the first term, r is the common ratio, and m is the number of terms.
In our case, the first term a is n, the common ratio r is 1/2, and the number of terms m is log2(n) + 1. Therefore, the sum of the terms is:
S = n(1 - (1/2)^(log2(n)+1)) / (1 - 1/2)
= n(1 - (1/2)^log2(n)*(1/2)) / (1/2)
= 2n(1 - (1/2)*1/n) / (1/2)
= 2n(1 - 1/2n) / (1/2)
= 4n(1 - 1/2n)
= 4n - 2
Hence, the solution to the recurrence relation T(n) = T(n/2) + n is T(n) = Θ(n).
By the above mathematical derivation, we have proved that T(n) = Θ(n) for the given recurrence relation using the expansion or tree approach.

Let B and C be two ordered bases of R^3, and consider a linear transformation T : R^3 -> R^3. Suppose that the change of base matrix Ic, B is given by [-3 -1 1] [-1 2 -1] [-1 -3 -2] and the coordinate matrix Tc,c of T with respect to C is given by [2 -2 -2][-1 -3 -1] [2 0 -1] Use this to determine coordinate matrix TB,B of T with respect to B! [ __ __ __ ]TB,B = [ __ __ __ ][ __ __ __ ]
The coordinate matrix of T with respect to the base B is [-9 -11 -8].
What is coordinate?Coordinate in math is a pair of numbers that represent a specific point in a two-dimensional space or a three-dimensional space. In two-dimensional space, it is written in the form (x, y) where x is the horizontal coordinate and y is the vertical coordinate. In three-dimensional space, it is written in the form (x, y, z) where x is the horizontal coordinate, y is the vertical coordinate, and z is the depth coordinate. Coordinates are used to plot points on a graph, calculate the distance between points, and to identify the location of a point.
Solution:
To determine the coordinate matrix of T with respect to the base B, we need to multiply the change of base matrix Ic,B with the coordinate matrix Tc,c of T with respect to C.
Multiplying the two matrices, we get:
TB,B = Ic,B × Tc,c
= [-3 -1 1][2 -2 -2] + [-1 2 -1][-1 -3 -1] + [-1 -3 -2][2 0 -1]
= [-9 -9 -7] + [-2 -2 4] + [2 -3 -5]

There are two cameras that take pictures of a traffic intersection. Camera A starts taking pictures at 6 AM and takes a picture every 11 minutes. Camera B starts taking pictures at 7 AM and takes pictures every 7 minutes. Camera A and Camera B take a picture at the same time at four different times before noon. When Camera A and Camera B take their last picture together, how many minutes before noon is it?
Answer:
41 minutes before noon
Step-by-step explanation:
The given parameters are;
The time camera A starts taking pictures = 6 AM
The frequency of picture taking by camera A = Once every 11 minutes
The time camera B starts taking pictures = 7 AM
The frequency of picture taking by camera B = Once every 7 minutes
The number of times both cameras take a picture at the same time before noon = 4 times
Let the time the two cameras first take a picture the same time be x, we have;
11·y - 60 = x
7·z = x
Taking the number of times after 7 camera A snaps and noting that the first snap is 6 minutes after 7, we have
11·b + 6 = x
7·z = x
x is a factor of 7 and 11·b + 6 and x is some minutes after 7
By using Excel, to create a series of values for Camera A based, on 11·b + 6, and dividing the results by 7 we have the factors of 7 at;
28, 105, 182, and 259 minutes after 7
Given that there are 60 minutes in one hour, we have;
259/60 = 4 hours 19 minutes, which is 11:19 a.m. or 41 minutes before noon.
