At a carnival, you spin a spinner that has four equal-sized sections, each a different color: green, yellow, red, and blue. If you land on green, you win 2 points. If you land on yellow, red, or blue, you lose 1 point. Write the expected value equation.

A= B= C=
D= E= F=
G=

Answers

Answer 1

Answer:

A= 4

B= 4

C= -1

D= 4

E= -1

F= 4

G= -1

Step-by-step explanation:

The expected value equation is the probability of something happening multiplied by the amount of times it happens. In this case you have four equal sized sections, so you have a one in four chance to land in any of these sections. A, B, D, and F represent the four for this one in four chance. C, E, and G represent the amount of points you get when you land on those sections, in this case -1

You found Genie hidden in a dungeon. Genie is offering two different options for you as a reward for finding him. There are two options shown for you to choose.

Which option would you choose? Explain your reasoning using the key features of exponential functions.

Answers

Answer:

The first option is

A(x) = 10000(1.05)ˣ

The second option is:

B(0) = 1000B(1) = 1100The ratio is 1.1 and the zero term is 1000

The equation for this option is:

B(x) = 1000(1.1)ˣ

Now, which option is better?

It depends on the number of x. It is assumed the genie is offering money or similar reward.

For the values of x below 50 option A is better and option B is much better for x > 50.

See the graph in the attachment, where green line represents the option A and red line is option B.

a) Possible set is:

The mean is different as we have now more numbers with different sum:

Perimeter is the length of the border. The best way to find it here is to split the figure up into a semicircle and a trapezoid.

The radius of the semicircle is 9 in. so its perimeter is 2pir/2 = 9pi in.

The perimeter of the trapezoid can be found by adding the lengths of all sides. The bottom side is 2 times the radius of the semicircle, 18 inches. Add this to the other lengths: 5 in, 12 in, 5 in.

The total perimeter is then 40 + 9pi.

Mr. Gascoigne's mind seemed to run on political topics, but whether relating to the past, present, or future, could not easily be determined, since the same ideas and phrases have been in vogue these fifty years. Now he rattled forth full-throated sentences about patriotism, national glory, and the people's right now he muttered some perilous stuff or other, in a sly and doubtful whisper, so cautiously that even his own conscience could scarcely catch the secret and now, again, he spoke in measured accents, and a deeply deferential tone, as if a royal ear were listening to his well-turned periods.

A: Mr. Gascoigne was fueled with feelings of patriotism and he felt compassion for his friends. B. Mr. Gascoigne was so thrilled to hear himself speak that he didn't care who was listening. C. Mr. Gascoigne became delirious and couldn't help talking incessantly to everyone. D. Mr. Gascoigne was feeling nostalgic and wanted to show off his knowledge of politics. E.
