Answer:
646.04 cm³
Step-by-step explanation:
<u>Cube volume formula:</u>
V=l*w*h
V=8*8*8
V=512
<u>Hemisphere volume formula:</u>
V=(4/3πr³)1/2
V=(4/3π4³)1/2
V=128/3
<u>Add both together</u>
128/3 + 512 ≈ 646.04cm³
Answer:
The estimate of the proportion of oil tankers that had spills is 0.25.
Step-by-step explanation:
Proportion of oil tankers that had spills:
1036 tankers.
777 did not have spills.
So 1036 - 777 = 259 had spills.
The proportion is:
The estimate of the proportion of oil tankers that had spills is 0.25.
The formula is,
(y [the second one] - y[the first one]) / (x [the second one] - x [the first one])
The first x=5, first y=12, second x=30, second y=72
Plug the numbers in, to get
(72-12) / (30-5)
Now just crunch it out.
(60) / (25)
=2.4
This is your answer.
Hope it helped!
