MATLAB PROBLEM

You are given an array, weights, that contains the weights of some cargo items in pounds. You want to load a truck with items from the list, up to its capacity. The truck has a maximum capacity of 1,000 pounds. For this problem use a "greedy" algorithm. That is, always load the heaviest item that will still fit on the truck. Keep loading until the remaining capcity of the truck is less than any of the remaining cargo items. For example, if the weights were {700, 400, 250, 100, 60}, you would load the 700-pound item, then the 250-pound item. The remaining items would be too heavy to fit on the truck. The weights will be generated randomly, so you cannot hard-code the answer - you must write a general algorithm to do it. Once the loading is complete, print a message indicating how many pounds of cargo were loaded onto the truck. NOTE: To satisfy the auto-grader, update the variable capacity so that it contains the remaining capacity of the truck. For example, if 943 pounds of cargo are loaded, capacity should be 57.

CODE PROVIDED BELOW

%The weights of the cargo items are generated at random

%They are sorted in descending order

weights = sort(randi(500, 1, randi(10)), 'descend')

capacity = 1000; %cargo capacity of the truck

A local college newsletter reported that the average American college student spends one hour​ (60 minutes) on a social media website daily. But you wonder if there is a difference between males and females. Attached below is a sample of 60 users of the website​ (30 males and 30​ females) and their recorded daily time spent on the website. Complete​ (a) and​ (b) below.

a. Assuming that the variances in the population of times spent on the website per day are​ equal, is there evidence of a difference in the mean time spent on the website per day between males and​ females? (Use a 0.05 level of​ significance.)

Let m1 be the mean daily time spent on the website for male college students and m2 be the mean daily time spent on the website for female college students. Determine the hypotheses. Choose the correct answer below.

Determine the test statistic.

Find the​ p-value.

Choose the correct conclusion below.

b. In addition to equal​ variances, what other assumption is necessary in​ (a)?

A. In addition to equal​ variances, it must be assumed that the samples are specifically chosen and not independently sampled.

B. In addition to equal​ variances, it must be assumed that the sample means are equal.

C.In addition to equal​ variances, no other assumptions must be made because the sample sizes are large enough ​(greater than or equals≥30 for each​ sample).Your answer is correct.

D. In addition to equal​ variances, it must be assumed that the population sizes are equal.

You are a professional robber planning to rob houses along a street. Each house has

a certain amount of money stashed, the only constraint stopping you from robbing

each of them is that adjacent houses have security system connected and it will

automatically contact the police if two adjacent houses were broken into on the same night.

Given a list of non-negative integers representing the amount of money of each house,

determine the maximum amount of money you can rob tonight without alerting the

police.

Suppose inflation rate is 6% for the past year. The inflation rate is expected to be 5% in the coming year and 4% per year thereafter. Assume that the real risk free rate r*, will remain at 2% over the next 10 years. The yield on a 5-year Treasury bond is 6.3% and the yield on a 10-year corporate bond is 8.4%. A 5-year corporate bond has the same maturity risk premium as the 5-year Treasury bond described. The 5-year corporate bond also has the same default risk premium and liquidity premium as the 10-year corporate bond described. Given that the maturity risk premium for the 10-year corporate bond is 0.3%, what is the yield on the 5-year corporate bond?

Ans : 8.3%

Medical Calculator

Create a python program that allows the user to enter the following patient information:

• First name and Last name
• gender
• age
• weight
• height
• systolic pressure and diastolic pressure
• current body temperature in degrees Fahrenheit

Once the information is entered then the results should be printed on the display based on the information below:

• BMI
• Temp Conversion
• Mean Blood Pressure
• Weight Conversion (lbs to kg)
• Height Conversion (inches to cm)

Output should be in the following format:

First Name Last Name is ___ cm and ___ kg's. First Name Last Name has a BMI of ___ , a temperature of ___ degrees Celsius, and his or her Mean Blood pressure is ___ mmHG. Mr or Ms Last Name is considered ____ (from the government BMI standards) and he or she has low/normal/high blood pressure.

Hint: all conversion formulas, BMI standards, and what is considered hi/normal/low BP's can be found online. The output should address the user by using Mr or Mrs and he or she.
