a compound tube of 300mm external and 100 mm internal diameter is formed by shrinking one cylinder onto another, the common diameter being 200 mm if the maximum hoop tensile stress induced in the outer cylinder is 90mn/mm². find hoop stress in the inner and outer diameter of both cylinders
A commuter train carries 600 passengers each day from a town to a city. A one-way trip costs 100 per person. Market research reveals that 10 fewer people would ride the train with every 1 increase in the fare. What fare should be charged to get the largest possible revenue?
Let us now try comparing two numbers by letting the user input two different numbers and say "Greater" if the first inputted number is greater than the second one, and "Lesser" if it’s the other way around.
Let's go!
Input
A line containing two different numbers separated by a space.
1.2·1.02Output
A line containing a string.
GreaterConsider the two different techniques we used for implementing traversals of a binary
tree. Why must we check before the call to preorder when implementing as a method,
whereas we could check inside the call when implementing as a function?
You wish to create a database of stars. For each star, the database will store several megabytes of data. Considering that your database will store billions of stars, choose the data structure that will provide the best performance. With this data structure you should be able to find, insert, and delete stars. Justify your choice.
Problem 1:
What do understand by the terms prior and posterior probabilities in relation to Bayes’ theorem?
Problem 2:
The problem with this disease is that once the first symptoms are observed and the veterinarian contacted, it can take several days for tests to be conducted and the results to be obtained. During this time, the disease can spread to other farms. However it is possible to carry out a quick test by the farmer, which will correctly diagnose the disease 80% of the time. Unfortunately, the test is prone to give a false positive reading on 40% of occasions, i.e. the probability that the test will give a positive reading when in fact the disease is absent is 0.4.
- Draw a probability tree diagram to show how the prior probabilities and the conditional outcomes of the test can be combined to give the posterior probabilities.
Calculate the rate the infilation rate of the economy if the consumer price index for 2019 is 100.
1. The total number of missing values within the dataset.
2. Which column / feature requires correction in the type of value they hold?
3. After imputation of nulls with mean what is the average value of the compressive strength in concrete?
4. The feature that has a moderately strong relationship with compressive strength in concrete is?
5. Standardize the dataset using standardscaler(), split the dataset into train and test of proportions 70:30 and set the random state to 1. Build a Linear Regression Model on the data and the resulting r-squared value is between which range?
