Answer:

you can go on a maximum of 11 rides

Step-by-step explanation:

you first have to subtract 30 from 100 since that is the admissons fee.

So now you are left with 70 dollars.

You divide 70 by 6 since you need 6 dollars to go on each ride.

and 70 divided by 6 is 11.6666666667 but round it to 11 since that the whole number you're left with.

Given:

Required:

We have to find the height of the mountain and the distance between A and B.

Answer:

Area is 126.5 inches^2

Step-by-step explanation:

Mathematically, to calculate the area of the trapezoid, we use the following mathematical formula;

A = 1/2(a + b) h

here, a and b represents the two parallel sides which is 9 and 14 inches here and h which is the height is 11

Plugging these values into the equation, we have

A = 1/2(9 + 14)11

= 1/2(23)11 = (23*11)/2 = 126.5 inches^2

Answer:

8x+5=133

8x=128

x=16

Step-by-step explanation:

16 books

Answer:

He bought 16 books

Step-by-step explanation:

cost = flat fee + books * cost per book

133 = 5 +b*8 where b is the number of books

133 = 5+8b

Subtract 5 from each side

128 = 8b

Divide each side by 8

128/8 = 8b/8

16 = b

He bought 16 books

what is measure of variability ?

In statistics, the measure of variability is a term that refers to how spread out or dispersed a set of data is. In other words, it is a measure of how much the data points in a given set differ from each other.

In the given question,

Question 10: The answer is Burger Quick, because it has a larger median.

Question 11: The answer is Histogram, because it is the best graphical representation for displaying continuous data, like the number of carbohydrates in tortilla sandwich wraps.

Question 12: The answer is Bus 18, with a median of 12, because the median is the best measure of center to use for skewed data, and Bus 18 has a lower median than Bus 14.

Question 13: The answer is the IQR is the best measure of variability, and it equals 2.5, because the IQR is the best measure of variability to use for skewed data, and it is calculated as the difference between the 75th percentile and the 25th percentile, which in this case is 9 - 6.5 = 2.5.

Question 14: The answer is Paddleboarding, because the central angle can be calculated as (54/100) * 360 = 194.4°, and Paddleboarding has the closest central angle to 39.6°.

Question 15: The answer is 2,100, because you can use proportions to estimate that 63/150 of the sample prefers ketchup their hot dog, and then apply that proportion to the total attendance: (63/150) * 5,000 = 2,100.

The value of x at which the minimum value of y occurs in [0, 1] is B) 1/8

Given y = 3x^(4/3) - 2x

We are asked to determine the value of x at which the minimum value of y occurs in [0, 1].

                                    Now, dy/dx = 0

                                     4x^(1/3) - 2 = 0

                                             x^(1/3) = 1/2

                                                     x = 1/8

Here, dy/dx = 0 when x = 1/8

So calculating y at x = 0, 1/8, 1

y(x = 0) = 0

y(x = 1/8) =3 (1/8)^(4/3) - 2/8 =  -1/16

y(x = 1) = 1

Hence, y has a minimum value of -1/16 at x = 1/8

An Experiment is repeated 10 times compared to just 3 times, the results from the 10 repetitions would generally be considered more reliable.

True.

In general, conducting an experiment multiple times increases the reliability of the results. The more times an experiment is repeated, the greater the opportunity to collect data and observe patterns or trends. This allows for a more robust analysis and reduces the impact of random variations or errors that may occur in a single trial.

When an experiment is repeated multiple times, it helps to reduce the effects of outliers or anomalies that may occur in a single trial. By averaging the results over multiple repetitions, the overall outcome tends to be more representative and reliable.

In the context of statistical analysis, increasing the sample size (number of repetitions) can lead to more precise estimates of parameters and reduce the margin of error. It provides a better understanding of the underlying phenomenon being studied and allows for more confident conclusions.

Therefore, if an experiment is repeated 10 times compared to just 3 times, the results from the 10 repetitions would generally be considered more reliable. The larger sample size provides a stronger basis for drawing conclusions and making inferences about the population or phenomenon under study.

To perform the opposite translation, we add the opposite of the translation vector to the image point A': the coordinates of point A are (16, 5).

what is a vector?

In mathematics, a vector is an object that represents a quantity having both magnitude (or length) and direction. Vectors can be represented geometrically as arrows, where the length of the arrow represents the magnitude of the vector and the direction of the arrow represents the direction of the vector.

To find the coordinates of point A, we need to perform the opposite translation of moving along the vector 〈−6, 0〉 from the image point A'(10, 5). This is because a translation is a rigid motion that preserves the distance between points, so the distance between A and A' is the same as the distance between their respective translations.

To perform the opposite translation, we add the opposite of the translation vector to the image point A':

A = A' - 〈-6, 0〉 = (10, 5) - (-6, 0) = (16, 5)

Therefore, the coordinates of point A are (16, 5).

Sammy originally took out approximately $5357.14 to fund his education.

The rate of interest, also known as the interest rate, is the percentage amount charged by a lender or financial institution for the use of borrowed money or for the extension of credit. It is the cost of borrowing money, typically expressed as an annual percentage of the amount borrowed or owed.

Let X be the amount Sammy took out originally to fund his education.

After 5 years, the amount he has to pay back is X + (0.08X5) = X + 0.4X = 1.4X.

We know that 1.4X = $7500, so we can solve for X:

1.4X = $7500

X = $7500 / 1.4

X ≈ $5357.14

The four equilibria of  differential equation  x' = sin(2x) whose interval is x € [0, 3π/2] are:  x = kπ/2 for k = 0, 1, 2, 3 . The equilibria at x = π/2 and x = 3π/2 are unstable, and the equilibria at x = 0 and x = π are stable.

To find the equilibria, we need to set x' = 0 and solve for x. Thus, sin(2x) = 0, which implies 2x = kπ where k is an integer. Therefore, x = kπ/2 for k = 0, 1, 2, 3. These are the four equilibria of the differential equation.

To determine the stability of the equilibria, we need to examine the sign of x' near each equilibrium. We know that sin(2x) is positive for x in the intervals (kπ/2, (k+1)π/2) where k is an even integer, and negative for x in the intervals (kπ/2, (k+1)π/2) where k is an odd integer.

Thus, for x near x = kπ/2 where k is even, x' is positive, which means that x will increase and move away from the equilibrium. Similarly, for x near x = kπ/2 where k is odd, x' is negative, which means that x will decrease and move away from the equilibrium.

The general solution of the given problem is y = Ce^(-x) - x^3 - 6(x + 1)^2, where C is a constant. To find the general solution, we first rearrange the given equation to isolate the derivative term, which gives us y' = -[6(x + y)^2 + y^2e^xy + 12x^3]/[e^xy + xye^xy + cos y + 6(x + y)^2].

Next, we separate the variables by multiplying both sides of the equation by dx and dividing by the numerator on the right-hand side. Integrating both sides gives us ∫[1/(-[6(x + y)^2 + y^2e^xy + 12x^3]/[e^xy + xye^xy + cos y + 6(x + y)^2])]dy = ∫dx. Simplifying the integral on the left-hand side leads to ∫[e^xy + xye^xy + cos y + 6(x + y)^2]dy = ∫dx. Integrating each term separately and solving for y gives us the general solution y = Ce^(-x) - x^3 - 6(x + 1)^2, where C is a constant.

Abrasion is the process of scraping or wearing away something. If weathering has worn away the letters, it has been abrasion weathering.      

This is equal to 0.04 plus 1.96 into root over 0.04 into 0.96 divided by 400 point. This is equal to 0.059, which is equal to 5.9 percent. Therefore, double 0 to 5.9 percent represent babies born with defect.

According to one research, 28 out of every 400 kids born in the globe suffer some form of serious birth problem. To execute a simulation based on this data, the easiest approach to assign random numbers is to use 00-06 (7%) to identify the newborns with birth abnormalities.

It is to be noted that:

The sum total of births is: 400

The sum of defective babies = 28

Hence, the fraction or ratio of this is:

28/400

because it is the answer that I think of

a) No length that is the same as AD.

b) No length that is the same as BC.

a) To find a length definitely the same as AD, we need to identify a line segment that shares the same properties with AD.

Since the circle is centered at O, and A and D are points on the circle, we can conclude that AD is a chord of the circle. Another chord in the circle is BC, as both B and C are points on the circle as well.

However, without further information about the circle or the angles, we cannot determine if AD and BC are definitely the same length.

So, there is no length that is definitely the same as AD.
b) To find a length definitely the same as BC, we need to identify a line segment that shares the same properties with BC. As mentioned earlier, BC is a chord of the circle.

Another chord in the circle is AD, but as stated previously, we cannot determine if AD and BC are definitely the same length without additional information.

So, there is no length that is definitely the same as BC.
