Answer:

The pilot was scheduled to depart at 4:00 p.m.

Her departure has been delayed by 16 minutes.

Air traffic control approved a new flight plan that will allow her to arrive four times faster than she calculated in her original flight plan.

We want to create an equation that can be used to predict the number of minutes after 4:00 p.m. she will arrive at her destination.

First, let's represent the time of her original flight as x, in minutes. This means that her original flight plan would have taken x minutes to arrive at her destination.

However, with the new flight plan approved by air traffic control, she will arrive four times faster than she calculated in her original flight plan. This means that her new flight plan will take x/4 minutes to arrive at her destination.

Now, we need to take into account the 16-minute delay in her departure. This means that she will depart at 4:16 p.m. instead of 4:00 p.m., and therefore arrive at her destination x/4 minutes after 4:16 p.m.

So the equation that can be used to predict the number of minutes after 4:00 p.m. she will arrive at her destination is:

Number of minutes after 4:00 p.m. = 16 + x/4

Note that this equation assumes that her flight time is the only factor affecting her arrival time, and does not take into account any other delays or factors that may affect her flight.

The sample sizes for the two universities need to be identical in order for their sampling distributions to have about the same standard deviation.

A sampling distribution is a probability distribution that specifies how a statistic—like the mean or standard deviation—behaves when it is generated from population-based samples of a specific size. It is crucial to statistical inference because it makes it easier to calculate the likelihood of receiving specific sample statistics from a population and to draw conclusions about the characteristics of the population from the sample data. The population factors and sample size both have an impact on the form, centre, and spread of a sampling distribution.

The size of the sample for the sampling distributions is given as:

n1 = (s1 / s2) * n2

where n1 and n2 are the sample sizes for College A and College B respectively.

We may assume that the variances of the two populations are identical as we want the sampling distributions to have about the same standard deviation. As a result, we may make the formula as follows by setting s1 = s2:

n1 = n2

We may draw the conclusion that the sample sizes for the two universities need to be identical in order for their sampling distributions to have about the same standard deviation.

Answer:

Step-by-step explanation:

Let's start by defining some variables to represent the amount invested in the CD and the mutual fund. Let:

C = amount invested in the CD

M = amount invested in the mutual fund

From the problem statement, we know that:

C + M = 60,000 (the total investment amount is $60,000)

C >= 2M (twice as much should be invested in CDs as in the mutual fund)

M >= 8,000 (the mutual fund requires a minimum investment of $8,000)

We can use these constraints to write the objective function that we want to maximize, which is the total return on investment:

R = 0.08C + 0.07M

To solve this problem, we can use the following steps:

Substitute C = 2M into the first equation to get:

3M = 60,000

M = 20,000

Since M >= 8,000, we can invest the minimum required amount in the mutual fund and put the rest in the CD:

M = 8,000

C = 60,000 - M = 52,000

Calculate the total return on investment:

R = 0.08C + 0.07M = 0.08(52,000) + 0.07(8,000) = 4,960 + 560 = 5,520

Therefore, the investor should invest $52,000 in the CD and $8,000 in the mutual fund to maximize the return, and the maximum return is $5,520.

The two points on the line to graph the function is (3, 4/3) and (-6, 10/3).

A line is a one-dimensional, straight shape that can go on forever in both directions. It is made up of an infinite number of points that are organized in a straight line.

We are unable to offer two points on the line for graphing in the absence of a line or function.

We consider the function is, [tex]f(x) = 2 - \frac{2}{9} x[/tex]

To graph the function [tex]f(x) = 2 - \frac{2}{9} x[/tex] , we can choose any two values of x, plug them into the equation to find the corresponding values of y, and then plot the points (x, y) on the coordinate plane. Here are two possible sets of points we can use:

Set 1:

Let x = 0:

f(0) = 2 - (2/9)(0) = 2

Therefore, one point on the line is (0, 2).

Let x = 9:

f(9) = 2 - (2/9)(9) = 0

and another point on the line is (9, 0).

Now, we can plot these two points on the coordinate plane and draw a straight line passing through them to graph the function [tex]f(x) = 2 - \frac{2}{9} x[/tex]

Set 2:

Let x = 3:

f(3) = 2 - (2/9)(3) = 2 - (2/3) = 4/3

So one point on the line is (3, 4/3).

Let x = -6:

f(-6) = 2 - (2/9)(-6) = 2 + (4/3) = 10/3

So another point on the line is (-6, 10/3).

Now, we can plot these two points on the coordinate plane and draw a straight line passing through them to graph the function [tex]f(x) = 2 - \frac{2}{9} x[/tex]

Therefore, the two points on the line to graph the function is (3, 4/3) and (-6, 10/3).

The y-coordinate value of Point C if the area of ABC is 9 units squared is: 5 or -1

Point A is at (x, 2) and B is at (x + 6, 2). Since AB must lie on the line y=2  and be 6 units long. Point C is on the line x = -3 . So let C be at (-3, y).

Since ΔABC is a right angle, then point C must have the same x-coordinate as point A. Therefore, A(-3, 2) and B(2, 2).

The area of ΔABC is 9. So,

9 = 1/2 (b)(h)

where b is the base and h is the height.

so b = 6 and h = AC

Solving this for AC gives

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

Point C must lie 3 units above point A or 3 units below the point A. If it lies 3 units above, then it has a y-coordinate of 2 + 3 = 5.

If it lies 3 units below, it has a y-coordinate 2 - 3 = -1.

The base of the triangles is 17 units and the height is 8 units.

Therefore, the area of each triangular base is:

[tex]\begin{aligned}\implies \sf Area\;of\;triangular\;base\;(A_B)&=\sf\dfrac{1}{2} \cdot17 \cdot8\\&=\sf 68\;square\;units\end{aligned}[/tex]

Therefore, the values to substitute into the total surface area formula are:

[tex]\begin{aligned}\implies \textsf{Total Surface Area}&= \sf 2 A_B+(a+b+c)h\\&= \sf 2 (68)+(11+14+17)10\\&=\sf 2 \left(68\right)+(42)10\\&=\sf 136+420\\&=\sf 556 \; square\;units\end{aligned}[/tex]

Answer:

Step-by-step explanation:

a. We can start by substituting y = 2x into the second equation to get an equation in terms of x only:

8x + 16y - 128 = 8x + 16(2x) - 128 = 0

Simplifying this equation, we get:

24x = 128

Solving for x, we get:

x = 128/24 = 32/6 = 16/3

So you and your friend work 16/3 hours (or approximately 5.33 hours) each at the second job.

b. If both of you work the same number of hours at the second job, then we can set x = y in the first equation and solve for y:

4x + 8y = 64

4x + 8x = 64

12x = 64

x = 64/12 = 16/3

So both you and your friend work 16/3 hours (or approximately 5.33 hours) at the second job.

To compare the number of hours worked at the first job, we can substitute x = 16/3 into the first equation to find:

4(16/3) + 8y = 64

64/3 + 8y = 64

8y = 64 - 64/3 = 128/3

y = 16/3

So your friend works 16/3 hours (or approximately 5.33 hours) at the first job, which is twice the amount of time you work at the first job.

We can identify the data values with a frequency of 2 on the line plot, which are 3/16, 5/8, and 1/2.

A line plot is a visual representation of data that shows the frequency of values in a dataset. In the given line plot, we need to identify the data values that have a frequency of 2.

Firstly, we have a data value of 3/16 that has a frequency of 2. This means that the value 3/16 appears twice in the dataset.

Next, we have a data value of 5/8 that also has a frequency of 2. This means that the value 5/8 appears twice in the dataset.

Lastly, we have a data value of 1/2 that has a frequency of 2. This means that the value 1/2 appears twice in the dataset.

Therefore, the data values that have a frequency of 2 on the given line plot are 3/16, 5/8, and 1/2.

Distance is the numerical measurement of how far apart two objects are. It is measured in units such as kilometers, meters, miles, feet, inches, and more. Distance can be calculated in one, two, or three dimensions. Distance is a key factor in many real-world applications, such as navigation, transport, and communication. Distance can also be used to describe relationships, such as the connection between two people.

A)To work out the distance travelled on a cycle in the first 14 seconds, we must first determine the velocity of the cycle. This can be done by dividing the distance travelled by the time taken. For example, if the cycle travelled 50 metres in 14 seconds, the velocity would be 50 / 14 = 3.57 metres per second. The distance travelled in the first 14 seconds would then be 3.57 x 14 = 49.98 metres.

B) To work out the acceleration speed in the first 4 seconds, we must first determine the change in velocity over the period of time. We can do this by subtracting the initial velocity from the final velocity. For example, if the cycle started at a velocity of 3.57 metres per second, and increased to 7.14 metres per second after 4 seconds, the acceleration would be 7.14 - 3.57 = 3.57 metres per second squared.

B. The inverse function is verified, such that f(g(x)) = x

The inverse of the function is solved as follows

f(x) = 3 / (7x + 1)

let f(x) = y, so that y = 3 / (7x + 1)

writing the equation by isolating x

y (7x + 1) = 3

7x + 1 = 3/y

7x = 3/y - 1

7x = (3 - y)/y

x = (3 - y)/7y

interchanging the variables

y = (3 - x)/7x

hence g(x) = (3 - x)/7x

solving for f(g(x)), to verify

f(g(x)) = 3 / (7((3 - x)/7x) + 1)

f(g(x)) = 3 / ((3 - x)/x) + 1)

f(g(x)) = 3 / ((3 - x + x)/x)

f(g(x)) = 3 / 3/x
