Based οn bοth the median and mean values, it appears that Bus 47 typically has the faster travel time cοmpared tο Bus 18.
We know that
Statistics is the discipline of mathematics concerned with data collection, analysis, interpretation, presentation, and organisation. It includes approaches for summarising and describing data, as well as inferring and forecasting based on the data.
Tο determine which bus typically has the faster travel time, we need tο cοmpare the measures οf center (mean and median) οf the twο buses.
The median represents the dataset's midway, where half of the values are above and half are below. The mean represents the dataset's average value, which is computed by adding all of the values and dividing by the total number of values.
When the medians are compared, we can see that Bus 47 has a higher median of 16, while Bus 18 has a lower median of 13. This shows that Bus 47 may have a faster average trip time.
However, we must also consider the methods. When the means are compared, we can see that Bus 47 has a higher mean of 16, whereas Bus 18 has a lower mean of 13. This lends credence to the notion that Bus 47 may have a faster average travel time.
Therefοre, based οn bοth the median and mean values, it appears that Bus 47 typically has the faster travel time cοmpared tο Bus 18.

During the first week of the "Cash for Clunkers" program, the average increase in gas mileage for the new car purchased versus the car traded in was 61%. If the average gas mileage of the new cars was 25.4 miles per gallon, what was the average gas mileage of the cars traded in? Round the answer to the nearest tenth.
The average gas mileage of the cars traded is 15.8 miles per gallon round to the nearest.
Let's assume that the average gas mileage of the cars traded in is x miles per gallon. According to the problem, the average increase in gas mileage for the new car purchased versus the car traded in was 61%. This means that the new car gets 61% more miles per gallon than the car traded in. We can express this relationship mathematically as:
25.4 = x + 0.61x
Simplifying the right-hand side of the equation, we get:
25.4 = 1.61x15.78
Dividing both sides by 1.61, we get:
x = 15.78
Therefore, the average gas mileage of the cars traded in was approximately 15.8 miles per gallon, rounded to the nearest tenth.
To understand this result, we can interpret it as follows: for the first week of the "Cash for Clunkers" program, the average gas mileage of the new cars purchased was 25.4 miles per gallon, which is 61% higher than the average gas mileage of the cars traded in. This suggests that the program was successful in incentivizing people to trade in their old, less fuel-efficient cars for new, more fuel-efficient cars.

If m<6= 97°, what is m<5
The measure of value of ∠5 is 83°.
Now, It is given that;
Two Lines m and n are parallel with each other and l is the transversal crossing the two given parallel lines.
And, m∠6 = 97°,
Since, Two rays combined into an angle have a single terminal. The point is known as the vertex of the angle, while the rays are known as its sides, occasionally as its legs, and occasionally as its arms.
Hence, Then by using the property of liner pair angles, we have
⇒ m∠5 + m∠6=180°
(Because they form a linear pair angles.)
⇒ m∠5 + 97 = 180
Subtract 97 both side, we get;
⇒ m∠5 + 97 - 97 = 180 - 97
⇒m∠5 = 180 - 97
⇒m∠5 = 83°.
Therefore, the value of the measure of ∠5 is,

2 defective screws out of 100 packs them in boxes of 500 probability of 15 defective screws
The term (100 C 15) represents the number of ways to choose 15 defective screws out of 100 packs.
In a scenario where there are 2 defective screws out of 100 packs, each containing 500 screws, we can calculate the probability of obtaining 15 defective screws. Let's assume that each pack is independent of the others.
The probability of a single screw being defective is 2/500, as there are 2 defective screws out of 500 in each pack.
Conversely, the probability of a screw being non-defective is 498/500.
To find the probability of obtaining exactly 15 defective screws, we can use the binomial distribution formula. The probability (P) can be calculated as follows:
P = (100 C 15) * (2/500)^15 * (498/500)^85
The term (100 C 15) represents the number of ways to choose 15 defective screws out of 100 packs.
By plugging these values into the formula and performing the calculations, the probability of obtaining exactly 15 defective screws can be determined. However, I am unable to perform the calculation for you within the given word limit.

Find all possible values of x.
Using the secant-secant theorem, the possible values of x are x = 6 and x = -10. -10 cannot be a value of x because length cannot be negative.
Secant-secant theorem: Calculating the value of of xFrom the question, we are to determine the value of x in the given diagram.
The Secant-secant theorem states that
"Given two secant segments which share an endpoint outside of the circle, the product of one secant segment and its external segment is equal to the product of the other segment and its external segment"
Thus,
We can write that
5 × (5 + 7) = x × (x + 4)
Simplifying
5 × 12 = x² + 4x
60 = x² + 4x
x² + 4x - 60 = 0
Solve the quadratic equation
x² + 4x - 60 = 0
x² + 10x - 6x - 60 = 0
x(x + 10) - 6(x + 10) = 0
(x - 6)(x + 10) = 0
x - 6 = 0 or x + 10 = 0
x = 6 or x = -10
Since x cannot be negative,
x = 6
Hence, the value of x is 6

The required derivative of f(x) = (3x² - 4x + 1)⁴ is f'(x) = 4(3x² - 4x + 1)³ * (6x - 4)
We can use the chain rule and power rule of differentiation to find the derivative of f(x).
Let u = 3x² - 4x + 1, then we have:
f(x) = u⁴
Using the chain rule, we get:
f'(x) = 4u³ * u'
To find u', we can differentiate u with respect to x using the power rule:
u' = d/dx (3x² - 4x + 1) = 6x - 4
Substituting u' and u into f'(x), we get:
f'(x) = 4(3x² - 4x + 1)³ * (6x - 4)

Answer: We can use both formulas to calculate the interest on an investment of $3500 at 2.75% for 3 years.
Using the formula A = P(1+r/n)^(nt), where A is the final amount, P is the principal amount, r is the annual interest rate as a decimal, n is the number of times interest is compounded per year, and t is the time in years, we have:
A = 3500(1+0.0275/1)^(1*3) ≈ $3843.84
Therefore, the interest earned is:
Interest = A - P = $3843.84 - $3500 = $343.84
Using the formula A = Pe^(rt), where A is the final amount, P is the principal amount, r is the annual interest rate as a decimal, t is the time in years, and e is the mathematical constant approximately equal to 2.71828, we have:
A = 3500e^(0.0275*3) ≈ $3843.84

Georgia will need [tex]\(\boxed{333}\)[/tex] square inches of cardboard to construct the square pyramid.
To calculate the amount of cardboard needed to construct the square pyramid, we need to find the surface area of each individual face and then add them together.
Given that the base of the pyramid is a square with side length [tex]\(b = 9\) inches[/tex] and the height of the triangular sides is [tex]\(a = 14\) inches[/tex], we can proceed as follows:
The surface area of the square base is [tex]\(b^2 = 9^2 = 81\)[/tex] square inches.
Each triangular face has a base equal to the side length of the square base, [tex]\(b = 9\) inches[/tex], and a height of [tex]\(a = 14\) inches[/tex]. Therefore, the surface area of each triangular face is [tex]\(\frac{1}{2} \times b \times a = \frac{1}{2} \times 9 \times 14 = 63\)[/tex] square inches.
Since there are four triangular faces in a square pyramid, the total surface area of the triangular faces is [tex]\(4 \times 63 = 252\)[/tex] square inches.
Adding the surface area of the square base and the total surface area of the triangular faces, we get [tex]\(81 + 252 = 333\)[/tex] square inches.
Therefore, Georgia will need [tex]\(\boxed{333}\)[/tex] square inches of cardboard to construct the square pyramid.

hat is the domain of the function on the graph?
Answer:
The domain of a function is the set of all possible input values for the function. In this case, the function is a graph, so the domain is the set of all possible x-values that correspond to points on the graph.
To find the domain, we need to consider all of the points on the graph. We can see that the graph extends infinitely to the left and right, so all real numbers are possible input values. Therefore, the domain of the function is all real numbers, or R.
Here is a more formal definition of the domain of a function:
The domain of a function is the set of all real numbers x for which the function f(x) is defined.
In other words, the domain is the set of all input values for which the function produces a valid output value.
