Internet service providers​ (isp) need to resolve customer problems as quickly as possible. for one​ isp, past data indicates that the likelihood is 0.80 that customer calls regarding internet service interruptions are resolved within one hour. out of the next 10 customer calls about interrupted​ service, what is the probability that exactly 7 will be resolved within one​ hour?

Answers

Answer 1
I think that the likelihood will still be 0.8 as that means that 8 out of 10 calls will be resolved within one hour so the 7 out of 10 falls within that likelihood so therefore the callers can go by that assumption and be fairly confident that they have quite a high likelihood of having their problems resolved within one hour.
Answer 2

To solve this problem, we make use of the binomial probability formula. That is:

P = [n! / (n – r)! r!] p^r * q^(n – r)

where,

n is the total number of customer calls = 10

r is the number of resolved customer calls = 7

p is the probability of resolving in one hour = 0.80

q is 1 – p = 0.20

 

Therefore,

P = [10! / (10 – 7)! 7!] 0.80^7 * 0.20^(10 – 7)

P = 0.2013 = 20.13%

When a typist changes from a conventional typewriter to a word processor, his typing schema will have to _____ to incorporate the new techniques needed for the new equipment?

Answers

Final answer:

A typist transitioning from a typewriter to a word processor needs to adapt their typing schema to effectively use the new features and functionalities offered by word processing software, enhancing productivity and document quality.

Explanation:

When a typist changes from a conventional typewriter to a word processor, his typing schema will have to adapt to incorporate the new techniques needed for the new equipment. The transition from a conventional typewriter to a word processor involves learning how to utilize features such as variable width fonts, WYSIWYG (what you see is what you get), and leveraging higher resolution output devices like laser and inkjet printers. This adaptation is crucial for taking full advantage of the productivity gains offered by modern word processing software, which can significantly increase the number of pages a typist can produce per hour compared to both manual and electric typewriters.

John is selling his pizza for $6 per slice in an area of high demand. However, customers are not buying his pizza.
Using what you learned about the principles of equilibrium, write three to four sentences about how John could solve his problem.

Answers

John's prices are too high. This is causing excess supply: John's workers can make many pizzas, but at these high prices, consumers are only demanding a small amount. If the price per slice decreased, consumers would demand more of John's pizza. This means that business would move toward a point of equilibrium, where supply matches demand at the appropriate price.

Using a "word" of 3 bits, list all of the possible signed binary numbers and their decimal equivalents that are representable in:

Answers

The sign bit is the high order bit, so that leaves two bits for the value. Two bits can represent 0-3. 2^2 possibilities.

Final answer:

Using a 3-bit word, the possible signed binary numbers range from -4 to +3, with the most significant bit indicating the sign. The numbers are 000 (+0), 001 (+1), 010 (+2), 011 (+3), 100 (-4), 101 (-3), 110 (-2), and 111 (-1) in binary and their corresponding decimal values.

Explanation:

The question involves listing all of the possible signed binary numbers and their decimal equivalents using a 3-bit word. In signed binary using 3 bits, we can represent a limited range of numbers, from -4 to 3. We use the most significant bit (MSB) as the sign bit where 0 denotes non-negative and 1 denotes negative.

It is important to note that using two's complement, the binary sequence 100 represents -4, which is the minimum value for a 3-bit signed binary number.

For 1.
Positive correlation means if you plot a country's population and land size on a graph. There would be a linear regression line that's sloping upwards. 

Since it's a scatterplot, there will be some that fall out of the line, but most of them should be on the line.

It's  (A)

For 2.
An outlier is a datapoint that's far, FAR away from the others, so it's (B)

For 3. (A), it's a single line-of-best fit that runs through the middle of the cluster of data points.
