Answer:

a) 64.37m^2   b) 15.71 meters

Step-by-step explanation:

Area of circle = \(\pi r^2\)

Rectangle: quadrilateral, parallelogram, all angles are 90 degrees

a) The area of the park not covered by the wading pool is equivalent to the area of the wading pool subtracted from the total area:

because the radius of the pool is 2.5

Area of wading pool = \(\pi 2.5^2=6.25\pi m^2\)

The total area of the park is length x width because it is a rectangle

Area of park = \(14*6=84m^2\)

Area of the park not covered by the wading pool = \(84-6.25\pi\) ≈ 64.37m^2

b) The meters of fence needed to surround the circular pool is the circumference of the circle

Circumference: \(2.5*2\pi=5\pi\) ≈ \(15.71\)

Step-by-step explanation:

Since V lies on UW,

UV + VW = UW

\(3x - 1 + x = 5x - 5 \\ 5x - x - 3x = 5 - 1 \\ x = 4\)

Therefore, VW = 4 units

We can answer the question by just looking at the horizontal line. The horizontal line goes through y = 5 where the values in the x-axis are between 1 and 4 without including them.

So, the only piecewise function that has one of the equations as:

f(x) = 4 for 1 < x < 4

is the option A.

We can also prove that for x less than 1, the equation of the line is f(x) = x+ 1 and for x greater or equal to 4, the equation of the line is f(x) = x - 1

For example: the first line goes through the point (0,1), so if x is equal to 0 (less than 1),

f(x) = x + 1 = 0 + 1 = 1

So, the answer is A

Answer:

Step-by-step explanation:

There are four 4s and four 7s in a deck of 52 cards, so the probability of drawing a 4 or a 7 is:

P(4 or 7) = P(4) + P(7) = 4/52 + 4/52 = 8/52

Simplifying this fraction, we get:

P(4 or 7) = 2/13

Therefore, the probability of getting a 4 or a 7 from a deck of 52 cards is 2/13, or approximately 0.1538 or 15.38%.

The probability of getting a 4 or a 7 is 2/13.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

You have a deck of 52 cards.

Number of cards which are 4 = 4

Number of cards which are 7 = 4

Number of cards which are either 4 or 7 = 4 + 4 = 8

Total number of cards = 52

Probability = 8/52 = 2/13

Hence the probability is 2/13.

The function is 130/2.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.

According to question,

In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1.

On average, it takes approximately 14 minutes for a plane to complete the entire arriving process, from radioing the control tower to landing on the runway, in the morning at Nogan Airport.

To determine the average time that elapses between a plane radioing the control tower and its completion of the entire arriving process in the morning, we need to consider the different steps involved in the process.

Radioing the control tower: The time between two consecutive arriving requests follows an exponential distribution with an average of 10 minutes. Hence, on average, it takes 10 minutes for a plane to radio the control tower after the previous plane.

Assigning position in queue: The air traffic controller assigns the plane a position in the queue on a first-come-first-serve basis, implying that there is no additional delay for this step.

Landing on the runway: Once the plane reaches the front of the queue, it lands on the runway. The time it takes for a plane to use a runway, either for landing or departing, follows an exponentially distributed process.

Since the runway dedicated to arrival can serve 15 flights per hour, the average time it takes for a plane to complete the landing process is 1/15 hour, or 4 minutes.

Considering these steps, the average time that elapses between a plane radioing the control tower and completing the entire arriving process in the morning can be calculated as follows:

Average time = Time to radio the control tower + Time to land on the runway

= 10 minutes + 4 minutes

= 14 minutes

The sample space for rolling a fair seven-sided die is S = {1, 2, 3, 4, 5, 6, 7}.

Given that,

A fair seven sided die is rolled.

We have to find the sample space of the rolling.

A sample space is a set of all the possible outcomes in a random experiment. It is usually denoted by the letter, S.

The subset of the sample space are events.

The die has the numbers marked from 1 to 7.

So when we roll the die,

The possible numbers are 1, 2, 3, 4, 5, 6, 7

Sample space = {1, 2, 3, 4, 5, 6, 7}

Hence the sample space is {1, 2, 3, 4, 5, 6, 7}.

BD = BC + CD = (7 + 17x)

BE = BA + AE = (8 + 13x)

By intersecting secants theorem:

\( BC\times BD = BA\times BE\)

\( 7(7+17x) = 8(8+13x)\)

\( 49+119x = 64+104x\)

\(119x -104x = 64-49\)

The length of the walkway is 24 ft, and you will need 24 stones to cover it.

The length of the walkway will be equivalent to the hypotenuse of a right triangle with cathetus of 23ft and 18ft, so we can use the Pythagorean theorem to get it:

L^2  =(23fy)^2 + (18ft)^2

L = √( (23fy)^2 + (18ft)^2 ) = 23.77ft

The walkway is 23.77 ft long.

Rounding to the nearest foot, the length is 24 ft.

b) If each stone covers 1 ft, then you will need 24 stones.

Step-by-step explanation:

Answer:

The correct answer is $9,100

Step-by-step explanation:

The effective annual rate for a 8.65% interest compounded monthly is 9.14%.

To calculate the effective annual rate, we need to take into account the compounding frequency. In this case, the interest is compounded monthly.

We can use the formula for compound interest to calculate the effective annual rate:

Effective Annual Rate = (1 + (interest rate / compounding frequency))^compounding frequency - 1

Plugging in the given values:

Effective Annual Rate = (1 + (8.65% / 12))^12 - 1

                     = (1 + 0.0072083)^12 - 1

                     = 1.0072083^12 - 1

                     ≈ 0.0914 or 9.14%

Therefore, the effective annual rate for a 8.65% interest compounded monthly is approximately 9.14%.

While implementing the bubble sort algorithm, the maximum number of comparisons that can take place for n elements are \(\frac{n(n -1)}{2}\)

When an array or list of items has to be rearranged, a sorting algorithm is used to compare the elements and sort the elements in the array or list. In each data structure, the new order of the items is determined using the comparison operator.

The simplest sorting method is called Bubble Sort, and it involves periodically exchanging nearby components if they are arranged incorrectly. Since the average and worst-case time complexity of this approach is relatively high, it is not appropriate for huge data sets.

According to the condition the maximum number of comparison can be found as follows:

Number of elemnts = n

Number of passes required by bubble sort of n elements will be = n-1

Therefore for the maximum number of comparisons that can take place for n elements will be = \(\frac{n(n -1)}{2}\)

The most appropriate graph to construct for the given data table is a line graph. It shows how the miles change over time between each individual data point, allowing us to observe the relationship between the number of days and miles driven.

A line graph is a suitable choice in this scenario because it visually represents the relationship between the number of days and the miles driven over time. In a line graph, the x-axis represents the number of days, and the y-axis represents the miles driven. Each data point (number of days, miles driven) is plotted on the graph, and a line is drawn connecting these points.

By using a line graph, we can observe the trend or pattern in how the miles driven change as the number of days increases. We can see if there is a linear or non-linear relationship between the variables and how the miles driven vary over time. The line connecting the points helps us visualize the overall trend and identify any significant changes or patterns in the data.

In contrast, a scatter plot would simply show the individual data points without connecting them, making it more suitable for displaying the distribution or clustering of data rather than showing the change over time.
