Answers

The wc command can be used to determine a file's line, character, word, and byte counts. We add the -l option to wc in order to count the number of lines. This will provide the file's name and the total amount of lines.

What lines are in the file when you close your file?

This is the simplest method for counting the lines in a text file in Python. Read all lines from a file and save them in a list using the readlines() function.

The length of the list, which is simply the total number of lines in a file, may then be determined using the len() function.

To see a file's initial few lines, use the head command. The head command will only print the first 10 lines by default. The coreutils package.

Therefore, already installed on our machine, is included with the head command. Be aware that spaces, tabs, and newlines all count as additional bytes.

Gabriel wants brain food for dinner the night before his final exam. What is best for him to eat? fried chicken and onion rings burgers and ice cream pizza and cookies grilled chicken and vegetables.

Answers

This is a good inquiry, especially applicable to the study of computers and technology.
It sounds like a prediction problem, in terms of measuring multiple variables calculating their betas and outputting the probability of choosing the following given we have a final the next day.

So let’s start by declaring variables for our model:

Calories: quantitative variable
Consumption time: time to eat the given food also quantitative
Cooking time: quantitative
Baking necessary: categorical 0 = no 1 = yes
Frying necessary: categorical 0 = no 1 = yes
Satisfaction brought: quantitative
Healthy: categorical 0 = no 1 = yes

Now create a data table for implementing our multinominal logistical regression function
I’ll be using 1 serving size for each measure
Fried chicken and onion rings
Cal: 320 (half chicken) + 240 (9 rings) = 560
Consumption time: 10 minutes (avg of sampling data with SD of 2.1 minutes)
Cooking time: 90 minutes + 20 minutes = 110 minutes (based on compiled recipes)
Baking: 0
Frying: 1
Satisfaction(max 10): 9 (-1 for oiliness)
Healthy: 0

Burgers and ice cream
Cal: 354 + 137(1/2 cup) = 491
Consumption time: 8 (mean with sd of 3.2)
Cooking time: 23 minutes (recipe) + 30 minutes (travel time to store and from) = 53 minutes
Baking: 0
Frying: 0
Satisfaction(max 10): 10
Healthy: 0

Pizza and cookies
Cal: 570 (2 slices) + 142 (1 cookie) = 712
Consumption time: 9 minutes (avg of sampling data with SD of 1.3 minutes)
Cooking time: 50 minutes + 72 minutes = 122 minutes (based on compiled recipes)
Baking: 1
Frying: 0
Satisfaction(max 10): 8 (not lactose intolerant friendly)
Healthy: 0

Grilled chicken and vegetables (roasted)
Cal: 162 (chicken breast) + 147 (1 cup) = 309
Consumption time: 9 minutes (avg of sampling data with SD of 1.46 minutes)
Cooking time: 30 minutes + 45 minutes = 75 minutes (based on compiled recipes)
Baking:1
Frying: 0
Satisfaction(max 10): 6 (cause chicken breast is dry and vegetables are nasty)
Healthy: 1

Now to develop our prediction model.
With training and validation data I was outputted the following beta coefficients.

X-int = 2.74
B1: -2.35 with p value of 0.002
B2: -0.72 with p value of 0.038
B3: -0.6 with p value of 0.047
B4: -1.2 with p value of 0.371
B5: -0.81 with p value of 0.016
B6: 2.91 with p value of 0.000
B7: 0.2 with p value of 0.007

Now building our prediction model we combine beta values with their coefficients then take e^x of each of the given options to find the probability of choosing each.

A credit card company receives numerous phone calls throughout the day from customers reporting fraud and billing disputes. Most of these callers are put "on hold" until a company operator is free to help them. The company has determined that the length of time a caller is on hold is normally distributed with a mean of 2.5 minutes and a standard deviation 0.5 minutes. If 1.5% of the callers are put on hold for longer than x minutes, what is the value of x? Use Excel, and round your answer to two decimal places.

Answers

Answer:

3.59 minutes

Explanation:

We solve this question using z score formula

Using Excel

Z-SCORE= (DataPoint-AVERAGE(DataSet))/STDEV(DataSet)

IN EXCEL,

AVERAGE, an excel function that calculates the Average of data set

STDEV.S: calculates the standard deviation while treating the data as a ‘sample’ of a population.

STDEV.P: This function calculates the standard deviation while treating the data as the entire population.

Z score formula = x - μ/σ

x = ?? μ = 2.5 minutes σ = 0.5 minutes

We are asked : If 1.5% of the callers are put on hold for longer than x minutes, what is the value of x?

Hence, Longer than = Greater than =

100 - 1.5%

= 100 - 0.015

= 0.985 ( 98.5%)

Using Excel we calculate = z score for 98.5 percentile

= 2.1701

Z score = x - μ/σ

2.1701 = x - 2.5/0.5

2.1701 × 0.5 = x - 2.5

1.08505 = x - 2.5

x = 1.08505 + 2.5

x = 3.58505

Approximately to 2 decimal places = 3.59 minutes

Therefore, 1.5% of the callers are put on hold for longer than 3.59 minutes.

What is linear model?

Depending on the context, the phrase "linear model" is used differently in statistics.

The word is frequently used interchangeably with a linear regression model since it occurs most frequently in relation to regression models.

The phrase has a different connotation when employed in time series analysis, though.

Something that is linear is related to a line. A line is built using all of the linear equations. A non-linear equation is one that cannot be represented by a straight line. It has a variable slope value and resembles a graphed curve.

The linear model's disadvantage is the distance between the transmitter and the receiver.

Thus, the correct option is D.
