Answer: The general term is an = 4n

Step-by-step explanation:

Answer:

  8/15

Step-by-step explanation:

You want the fraction of a rain gauge filled after 15 more minutes when the rain rate is 2/5 of the gauge in 3/4 of an hour.

15 minutes is 1/4 hour, so 15 more minutes brings the total time to 1 hour. The fraction (x) of the gauge that is filled will be ...

  x/1 = (2/5)/(3/4)

  x = (2/5)(4/3) = 8/15

After a total of 1 hour, the rain gauge will be 8/15 of the way full.

The surface area of the rectangular prism is 172cm^2

Prism is a three-dimensional solid object in which the two ends are identical. It is the combination of the flat faces, identical bases and equal cross sections. The faces of the prism are parallelograms or rectangles.

The surface area of prism is 2A+ pH

where A is the base area

P is the perimeter of the base

and h is the height

for a rectangular prism, the base area is 2×8=16cm^2

perimeter of a rectangle= 2(l+b)

= 2(8+2)

= 20cm

surface area =( 2× 16) + 20× 7

= 32+ 140

Number sequence is a progression or an ordered list of numbers governed by a pattern or rule. For example -

3, 6, 9, 12, 15

x, x + 2, x + 4, x + 6

We have the following sequence -

f(n) = 3n + 6

We can write the first four terms as -

f(1) = 3 x 1 + 6 = 9

f(2) = 3 x 2 + 6 = 12

f(3) = 3 x 3 + 6 = 15

f(4) = 3 x 4 + 6 = 18

The value of n is A. -1/2

The inequality that does not represent the position of 2 numbers on a number line is A. 4 1/2 > 25/4

A number line is a horizontal representation of number parts with equal intervals

The numbers in a number line is arranged to be increasing from left to right , hence drawing a number line will have the smaller values to the left of the bigger values

n is the negative side of the line and it is half (1/2) way between 0 and -1 hence should be -1/2

for the inequality, 4 1/2 > 25/4

4 1/2 = 4.5

25/4 = 6.25

4.5 should less than 6.25, and hence do not represent the correct position of two numbers

William will arrive home at 16:45, it will take 45 min to reach home.

Given, that William leaves work at 16:00

Distance from work to home is 36 kilometres

Also, he drives at an average speed of 48 km/hr

Now, using distance-speed relation to find the time

So, as we know Distance = Speed × Time

On putting the values of distance and speed, we get

36 km = 48 km/hr × Time

On dividing both the sides by 48, we get

36/48 = (48×Time)/48

36/48 = Time

Time = 0.75

Hence, he will take 0.75 hr to reach home.

0.75 hr ≈ 45 minutes

The likelihood that at least 150 people will collaborate and react in a fresh sample of 400 telephone numbers is 0.9953.

The probability informs us of the likelihood that an event will occur. It is necessary for the likelihood to fall between 0 and 1. The likelihood of success is 1, whereas the probability of failure is 0.

Given, that the market research  company has a history of having a 44% response rate for its telephone surveys.

Therefore, p=44%=0.44=μ

n=400

p=150/400

p=0.375

The standard deviation is then equal to,

σ=√(p(1-p))/n

σ=√(0.44(1-0.44))/400

σ=√(0.44×0.56)/400

σ=0.025

Using the z-table, the values are as follows:

z=(p-μ)/σ

z=(0.375-0.44)/0.025

z=-2.6

p(p>0.375)

=p(z>-2.6)

=1-p(z<-2.6)

=1-0.0047

The vertex form of the function g(x)= 2[tex]x^2[/tex]+16x+6 is g(x)= 2[tex](x+4)^2[/tex]-26.

What is vertex form of the function?

   The function's maximum or lowest possible output is represented by the vertex of the quadratic function's graph. When viewing a graph, the vertex is the highest or lowest point on the parabola. Utilizing the vertex formula is the simplest technique to discover the vertex. It is simple to locate the vertex of the parabola using the vertex form of a quadratic equation. Y=a(xh)2+k is the definition of the generic vertex form, where h is the x-coordinate and k is the y-coordinate of the vertex.

Here the given function is ,

=> g(x) = 2[tex]x^2[/tex]+16x+6

=> g(x) = 2([tex]x^2+[/tex]8x+3)

=> g(x) = 2([tex]x^2+[/tex]8x+16-16+3)

=>g(x) = 2 [[tex](x+4)^2[/tex]-13]

=> g(x)=  2[tex](x+4)^2[/tex]-26

Zimbardo did not use a control group. Experiments are performed to reach meaningful conclusions using the appropriate research method. The correct answer is (A).

Experiments whether they are done in natural settings or in a controlled environment need to follow certain ethics. But the Stanford Prison Experiment is an exception. In this experiment, Philip Zimbardo, the Stanford psychologist, took paid participants and asked them to be “guards” in a mock prison at Stanford University.

As soon as the experiment began, the “guards” began mistreating the “prisoners,” in order to provoke evil circumstantially. The conclusion of the study suggested innocent people, thrown into a situation where they have power over others, will begin to misuse that power. And people who are put into a situation where they are powerless will be driven to submission.

The Stanford Prison Experiment has proved to be a Fraud. Philip Zimbardo, the Stanford psychologist who did the experiment, and interviews of the participants, offers convincing evidence that the guards in the experiment were trained to be cruel. This proves that the experiment’s most memorable moment of a prisoner screaming out of rage and proclaiming, “I’m burning up inside!” was the result of the prisoner's acting skills. Many of them think of this study as more of a dramatic demonstration with no real outcomes. The Zimbardo prison experiment is a classic study that has been recently reevaluated and exposed as a fraud.

The insurance charge I (in dollars) is given by the function I=4.80 +0.15M.

and, Let C be the total charge (in dollars) for a rental that includes insurance.

To find the An equation relating C to M.

Now, According to the question:

By the topic:

The total Charge (C) = The standard Charge (S) + The insurance charge (I)

Thus,

The total Charge (C) = 18.95 +0.50M + 4.80 +0.15M.

Combine like terms:

The total Charge (C) = 18.95 + 4.80 + 0.50M + 0.15M
