Answer:

C). ABBA counterbalancing.

Explanation:

As per the question, the technique which the student should not use to balance the practice effects would be 'ABBA counterbalancing' as it repeats the conditions and dispenses them evenly to balance/counter the effects which is not appropriate in this context(as it follows the stages of improvement and could not be distributed).

Except for this one, any of the other three could be employed to balance the practice effects as block randomization involves division of subjects into blocks that would make it easier and convenient while Latin square design offers a statistical method of counterbalancing and 'all possible orders' exemplify the inclusion of every possible sequence to the conditions. Thus, <u>option C</u> is the correct answer.

Ira Lisetskai [31]
On this beautiful Saturday morning i decided to wake up to my alarm. Ever since Thursday i've been ignoring it and i didn't want it to be my third time ignoring it. I went outside to go pick some herbs and i saw a girl with a spear in her hand. She had blue eyes that sparkle when the sun hit them. she looked hurt. i went over to investigate. "hello! may i ask why you have a spear in your hand?" i asked. "oh hello, i actually just found it. i looked over and it was clear as day!" she said. "oh okay. would you like to come in for breakfast?" i asked. "i'd love to!" she exclaimed. we went inside and my cousin served us eggs. as we chatted, i learned she was an artist and a very interesting person. i would love to see her again some time!

Katrina had 2/3 of a gallon of ice cream she uses 1/6 gallon as a serving how many servings does she have explain by writing 2/3
vodka [1.7K]

Katrina has 4 servings

<em><u>Solution:</u></em>

Katrina had 2/3 of a gallon of ice cream

She uses 1/6 gallon as a serving

Therefore,

Total\ gallon\ of\ icecream = \frac{2}{3}\\\\Gallon\ for\ 1\ serving= \frac{1}{6}

<em><u>To find: Number of servings can be mad</u></em><em><u>e</u></em>

Number\ of\ servings = \frac{\text{total gallon of icecream}}{\text{ galon for 1 serving}}

Substituting the values we get,

Number\ of\ servings = \frac{\frac{2}{3}}{\frac{1}{6}}\\\\Number\ of\ servings = \frac{2}{3} \times \frac{6}{1}\\\\Number\ of\ servings = 4

Thus Katrina has 4 servings
