The statement “randomization in an experiment ensures that any

is TRUE. I am hoping that this answer has satisfied your query and

The theorem used to solve this is axa+bxb=cxc. First you would do 4.9x4.9=24.01. Next you would do 2.4x2.4=5.76. Next you would add 24.01+5.76=29.77. Lastly you would square it and round if needed.
