Consider the addition of the dummy variables classmidsize and classlarge to the simple linear regression model in part (a). the value of classmidsize is 1 if the car is a midsize car and 0 otherwise; the value of classlarge is 1 if the car is a large car and 0 otherwise. thus, for a compact car, the value of classmidsize and the value of classlarge are both 0. develop the estimated regression equation that can be used to predict the fuel efficiency for highway driving, given the engine's displacement and the dummy variables classmidsize and classlarge. let x1 represent engine's displacement. let x2 represent variable classmidsize. let x3 represent variable classlarge. if required, round your answers to four decimal places. for subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (example: -300) = + x1 + x2 + x3 how much of the variation in the sample values of hwympg does this estimated regression equation explain? if required, round your answer to two decimal places. %

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
