Using the computed t-score, the significant association between two categorical variables can be measured and established.
Answer: 284.7
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14*
(4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)
h
=(1/3)*3.14*
*9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
-12-(-8)
=-12+8
=-4
Double negative is the same as positive, so the two negatives cancel out to a plus sign.
