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)
Answer:
58.61%
Step-by-step explanation:
Your total backyard is 18ft * 9ft = 162 ft^2
Your patio is 5ft * 8ft = 40 ft^2
Your Garden is 4ft * 7ft = 28 ft^2
Your walkway is 3ft * 9ft = 27 ft^2
Add all those areas together you have 95 ft^2
95 of 162 = 58.61%
Answer:
[B] A two-sample t -test for a difference between means.
Step-by-step explanation:
"<u>A two sample t test for a difference in means was conducted to investigate whether the average time to swim a lap with the freestyle stroke is different from the average time to swim a lap with the butterfly stroke</u>."
The probability of the compliment of an event is sometimes less than the the probability of the event itself
First arrange numbers
14,15,15,17,19,20,21,23,24
19 is median
15+15/2=15 is first quartile
