X/4 + x/5 = 1
5x/20 + 4x/20=1
9x/20 =1
9x = 20
x = 2.22 hours
$11 is the independent and the $30 is dependent because to get the $30 a week, it depends on that $11 per house.
Answer:
it would remain unchanged
Step-by-step explanation:
It asks us that If the confidence coefficient is increased from 0.95 to 0.99, the standard error of the mean will
in this case it would remain unchanged, because standard error of the mean is = sd / (n ^ 1/2), that is, it does not intervene in the calculation, therefore it does not change
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
