Answer:
4/8 is steeper than 3/10
Step-by-step explanation:
4 is half of 8 and in decimal form is 0.5. 3/10 in decimal form is 0.3. Therefore 0.5 is greater than 0.3, so 4/8 is considered to be steeper than 3/10.
Let's look at the formula for the volume of a sphere:
Volume = (4/3) (pi) (radius)³ .
If you multiply the radius of a sphere by 'anything',
then the volume gets multiplied by (anything)³ .
Going the other direction, if you multiply the volume by
'something', then the radius gets multiplied by ∛(something).
In this question, the ratio of the volumes is 3 .
So the ratio of the radii (radiuses) is ∛3 = about 1.442 (rounded)
Correct Answer are A and D
The answer in slope-intercept form would be:
y=1/3x-3
Ratio in the first sample = 250/1000 = 1/4 = 0.25
ratio in the second sample = 750/2000 = 0.375
hence ,<span> there is a greater proportion of smokers in the second city than in the first.
