Answer for the question:
Use the Hurricanes data and via Multiple regression select the three input variables: Min-pressure, Gender, Category in order to predict the All-Deaths. Pick one of the three variables that has the best P-value and re-do the regression using ONLY this one variable to predict the All-deaths. Answer the questions. (Numerical answers are rounded so choose the answer that matches the best).
is explained in the attachment.

Answer:
Matlab code with step by step explanation and output results are given below
Explanation:
We have to construct a Matlab function that creates a row vector "countValues" with elements 1 to endValue. That means it starts from 1 and ends at the value provided by the user (endValue).
function countValues = CreateArray(endValue)
% Here we construct a row vector countValues from 1:endValue
countValues = 1:endValue;
% then we transpose this row vector into column vector
countValues = countValues';
end
Output:
Calling this function with the endValue=11 returns following output
CreateArray(11)
ans =
1
2
3
4
5
6
7
8
9
10
11
Hence the function works correctly. It creates a row vector then transposes it and makes it a column vector.
To indentify the machines in our school that have a pulley system as the drive mechanism and the advantages of Pulley system is given below
Explanation:
1.A pulley is a wheel with a groove along its edge, that holds a rope or cable. ... When pulleys are used together in this way, they reduce the amount of force needed to lift a load. A crane uses pulleys to help it lift heavy loads. Pulleys are one of the six simple machines.
2.Examples of pulleys include:
- Elevators use multiple pulleys in order to function.
- A cargo lift system that allows for items to be hoisted to higher floors is a pulley system.
- Wells use the pulley system to hoist the bucket out of the well.
- Many types of exercise equipment use pulleys in order to function.
3.Using multiple pulleys decreases the amount of force necessary to move an object by increasing the amount of rope used to raise the object. The mechanical advantage (MA) of a pulley system is equal to the number of ropes supporting the movable load.
4.To calculate the mechanical advantage of a pulley you simply have to count the number of rope sections that support whatever object you are lifting (not counting the rope that is attached to the effort). For example, in a one pulley system the MA is 1. ... Therefore your mechanical advantage would be 2 (600/300).
5.The movable pulley is used to reduce the amount of input force to lift a load. The most popular system that uses this pulley would be a well. Unlike the fixed pulley, the movable pulley is attached to the load, and is lifted by pulling up on the rope, making it twice as easier to lift a heavy object.
6.The main benefit of the pulley is that it can actually reduce the amount of force which is required to lift heavy objects and redistributes the direction of the force to lift heavy objects
