A farmer is interested to know if different types of cattle, Angus and Hereford, gain the same amount of weight using two different types of mixtures of grains, one with more corn and one with more milo. She is specifically interested in which type of feed is best for each type of cow. Draw the correct design for this experiment. (Hint: In the design, it is easier to start off with the type of grain.) Remember to clearly indicate what is randomized.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
