Answer:
The value of x would be 16.
Step-by-step explanation:
In a data,
Median : middle value of the data when the data is written is ascending order.
While,

Here, the given data is,
4, 5, 6, 8, 10, and x
So, median = = = 7.
Number of the observations = 6,
Sum of the observations = 4+ 5+6+8+10+x = 33 + x
Thus,
Average = 
According to the question,




Therefore, the value of x would be 16.
Given that t<span>here
are 20 light bulbs in 5 packages.
The table to find the rate
that gives you the number of light bulbs in 3 packages is given as follows:
![\begin{tabular} {|c|c|c|c|c|c|} Light bulbs&4&8&12&16&20\\[1ex] Packages&1&2&3&4&5 \end{tabular}](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%0A%7B%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7C%7D%0ALight%20bulbs%264%268%2612%2616%2620%5C%5C%5B1ex%5D%0APackages%261%262%263%264%265%0A%5Cend%7Btabular%7D)
Three different ways in which the rate can be written are:
12 light bulbs to 3 packages
12 light bulbs : 3 packages
12 light bulbs / 3 packages

Answer:
The amount of water she needs to pump in:
V = Base area x Height x 1/2 = (4/2)^2 x pi x 0.75 x 1/2 = 1.5pi = ~4.7 (ft3)
=> Option D is correct.
Hope this helps!
