How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
We are given that;
The point at (60, 55)
Now,
This means that customers who enter the special discount code can save $5 on this particular item.
In general, the point (x, y) on the graph represents an item with an original price of x dollars that is being sold at a sale price of y dollars. The graph is showing how the sale price of items changes as the original price increases.
Therefore, by the graph the answer will be $60 and $55.

The Answer is 1/4
Step-by-step explanation:
The required constant of variation for given data is k = 1/4
The correct option is (a)
What is constant of variation?In a direct variation, the product of two variables; in an inverse variation, the ratio of two variables, is called constant of variation
Formula:
k = \(\frac{n}{fg}\)
How calculate constant of variation?Here we have given that n = 4, f = 2 and g = 8

En un triatlón, Jenny nadó durante 1 hora, anduvo en bicicleta durante 1,75 horas y corrió durante 1 hora. Su velocidad promedio en bicicleta fue 2 veces su velocidad promedio para correr, y su velocidad promedio para correr fue 8 veces su velocidad promedio para nadar. La distancia total del triatlón fue de 55,5 kilómetros. Escribe una ecuación y resuélvela para encontrar la velocidad de nado promedio de Jenny en kilómetros por hora. Explique su ruta de solución y el razonamiento detrás de su trabajo.
Jenny's Average swimming speed is 1.5 km/h.
Jenny's average swimming speed as S (in km/h). We can then use the given information to set up equations and solve for S.
We know that Jenny swam for 1 hour, so the distance she swam is given by the formula: Distance = Speed * Time.
Thus, the distance she swam is S * 1 = S km.
Next, we know that her average running speed is 8 times her average swimming speed. Therefore, her average running speed is 8S km/h.
Since she ran for 1 hour, the distance she ran is 8S * 1 = 8S km.
Furthermore, we are given that her average bicycling speed is 2 times her average running speed. Therefore, her average bicycling speed is 2 * 8S = 16S km/h.
She biked for 1.75 hours, so the distance she biked is 16S * 1.75 = 28S km.
The total distance of the triathlon is the sum of the distances for each segment: Distance(swimming) + Distance(running) + Distance(biking) = 55.5 km.
Therefore, we can write the equation:
S + 8S + 28S = 55.5.
Simplifying the equation, we get:
37S = 55.5.
To solve for S, we divide both sides of the equation by 37:
S = 55.5 / 37 = 1.5.
Thus, Jenny's average swimming speed is 1.5 km/h.

Which graph is growing at a slower rate?
graph a or b
Answer:
B.
Step-by-step explanation:
The graph of b is a linear graph, meaning it's value will increase at the same rate. The graph of a, however, appears to be exponential. This means that a will increase at a rapidly higher rate that b over time. You can also tell by just looking. You can see graph a has overtaken b in the same amount of time.

For 100 chemistry tests, the mean score was 40 and the standard deviation was 10. However, two tests were wrongly scored as 30 and 70 in place of 3 and 27 respectively. Find the correct standard deviation.
The correct standard deviation here is 24.25
How to find the standard deviation?You can adjust the standard deviation accurately, using a VERY useful algebraic identity.
Given that we don’t have all the xi or the xi - mean, but here’s a nice identity:
sum( (xi - mean )2) = sum(xi2) - (1/n)( sum(xi) )2
in other words,
(sum of the squares) minus (1/n)*(square of the sum)
We will start with the original numbers before the error was detected:
STD = 10
Sum(xi) = 4000
using the new identity,
std = \(\sqrt\)(sum(xi2) - (1/n)( sum(xi) ))2
From this, we can solve for sum(xi2)
std2= sum(xi2) - (1/n)(( sum(xi) )2)
sum(xi2) = std2 + (1/n)( (sum(xi))2 )
100 + 40002/100 = 160100
Now we can change those numbers to make the new standard deviation
The new sum(xi ) is the old sum minus the erroneous scores (30 and 70) plus the correct values (3 and 27) =
4000 -30 -70 + 3 + 27 = 3930
The new sum(xi2) Is the old sum minus the squares of the erroneous scores (900 and 4900) plus the squares of the correct scores (9 and 729) = 160100 -5800 + 738 = 154300+738 = 155038
Now the new standard deviation is
std = \(\sqrt(sum(xi2)\) - (1/n)( (sum(xi))2)
= \(\sqrt( 155038 - 39302/100)\\= \sqrt( 155038 - 15444900/100)\\= \sqrt( 155038 - 154449)\\= \sqrt( 589 )\)
= 24.25
Therefore, the correct standard deviation is 24.25

Ethan decides to type up some documents while waiting the meeting to start.He can type 2 pages every 1/8 hour.If the meeting started 3/4 hour later than the scheduled time,how many pages can he type before the meeting starts?
Answer: 4 pages
Step-by-step explanation:
To solve this problem, we need to use the formula:
Rate = Output/Time
Let's use "p" to represent the number of pages Ethan can type and "t" to represent the time he has before the meeting starts.
Rate = 2 pages/(1/8 hour) = 16 pages/hour
Since the meeting starts 3/4 hour later than the scheduled time, Ethan has t = 1 - 3/4 = 1/4 hour to type pages before the meeting starts.
Output = Rate * Timep = (16 pages/hour) * (1/4 hour) = 4 pages
Therefore, Ethan can type 4 pages before the meeting starts.
Answer: 4 pages
Please help I'm Timed Will Name Brainliest if Correct.
Answer:
A
Step-by-step explanation:
We can see that Function A's y coordinate doubles every time. The function A = f(x) = 5(2)^x. It is an exponential growth function, and therefore y can never be 0. This means that A does not have an x-intercept.
Function B is a rational function. x cannot be 0, since that would result in an undefined number. This also means that B does not have an x-intercept.

What is a triangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes.
In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane. In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle.
If all of geometry is the Euclidean plane, then all triangles are enclosed in a single plane, however in higher-dimensional Euclidean spaces, this is no longer the case. Except when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.

Diane will spend less than $27 on gifts. So far, she has spent $16. What are the possible additional amounts she will spend?
Use c for the additional amount (in dollars) Diane will spend.
Write your answer as an inequality solved for c.
Answer:
Step-by-step explanation:
Diane will spend less than $27 on gifts, and she has already spent $16. Therefore, the maximum amount she can spend on additional gifts is:
$27 - $16 = $11
Let c be the additional amount (in dollars) Diane will spend. Then, we can write the inequality:
c < $11
This means that the additional amount Diane spends (c) must be less than $11 in order for her total spending on gifts to be less than $27.

A number cube numbered 1-6 is rolled 30 times and lands on an even number 18 times.
How does this frequency compare to the expected frequency based on the probability of
the number cube landing on an even number?
The frequency is 15 more than expected.
The frequency is 13 more than expected.
The frequency is 9 more than expected.
The frequency is 3 more than expected.
Done →
Given statement solution is :- The correct answer is: The frequency is 3 more than expected.
To determine the expected frequency of landing on an even number when rolling a fair six-sided number cube, we need to calculate the probability of landing on an even number and multiply it by the total number of rolls.
The number cube has six possible outcomes: 1, 2, 3, 4, 5, and 6. Of these, three are even numbers: 2, 4, and 6. Therefore, the probability of rolling an even number is 3/6, which simplifies to 1/2 or 0.5.
The expected frequency can be found by multiplying the probability by the total number of rolls:
Expected frequency = Probability of landing on an even number × Total number of rolls
Expected frequency = 0.5 × 30 = 15
Now, we can compare the expected frequency (15) to the actual frequency (18) given in the problem statement.
The actual frequency is 18, and it is 3 more than the expected frequency (18 - 15 = 3).
Therefore, the correct answer is: The frequency is 3 more than expected.
