Answer:a) C = 2πr
b) 37.68feet
c) r = C/2π
d) 5.89feet
Step-by-step explanation:
Vcylinder=hpir^2
Vsphere=(4/3)pir^3
Vcone=(1/3)hpir^2
Vcylinder=15*pi*5^2=375pi in^3
Vsphere=(4/3)*pi*6^3=288pi in^3
Vcone=(1/3)*15*pi*8^2=320pi in^3
greatest is Vcylinder at 375pi in^3
answer is A (cylinder)
The construction for the two sided and one sided hypothesis
is the same so the answer is letter d. the explanation behind this is: If you
use a two-tailed test it just means that you need to allot half of your alpha
to testing statistical significance. If your alpha is equal to 0.05, then this
means that 0.025 must be in each tail of the distribution while for the one-tailed
test, you will only allot your alpha in one-side.
Answer:
|d| = √(-1-(-3)² + (-2-(5))²
d = √4 + 49
d = √53
d = 7.280
d = 7.28 2dp
