To find the average (aka mean) of a group of numbers, all we need to do is add them up then divide that number by how many numbers we started with
23 + 21 + 24 + 22 = 90
90 ÷ 4 = 22.5
Therefore, the average distance the book traveled on ice is 22.5 cm
15 + 18 + 16 + 17 = 66
66 ÷ 4 = 16.5
Therefore, the average distance the book traveled on concrete is 16.5 cm
In conclusion, the average distance the book traveled on ice is greater than the average distance the book traveled on concrete
Hope this helps you

it's the only volume quantity in the list ??? the rest are lengths ???
It depends on how old you are becuase every age has a different amount that they have to do
Electrical things in parallel are typical of circuit elements in homes.
Electrical things in series are not typical of circuit elements in homes.
Every electrical thing in a house is in parallel. Sometimes they're also in parallel with the electrical devices in other houses nearby.
Spurs are probably the result of <u>self-sustaining</u> <u>star formation.</u>
<h3>What is the formation of gaseous spurs in spiral galaxies?</h3>
The gigantic form of the magnificent doppelganger spiral patterns that spiral outward from the galactic cores gave spiral galaxies their name. These light arms of spiral galaxies are frequently seen in optical pictures to be speckled with bright star-forming areas at regular intervals.
Smaller structures spread forth and rearward into the interarm area from each major spiral arm. Spiral-arm also known as spurs are the name given to these substructures. Sometimes the spurs are also filled with star-forming clusters. As a consequence, we may draw the conclusion that spurs most likely emerge from self-sustaining star formation.
