The second quartile Q₂ is nothing but the Median.
This means that it median = 4.2
To write 0.09 as a decimal you have to divide numerator by the denominator of fraction 0.09 us not a fraction so it is a decimal already and finally we have 0.09 as a decimal equals 0.09
9/100=0.09 also

Answer:
"The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are." -- Math is Fun
7x-4=2
add 4 to both sides
7x=2+4
7x=6
divide 7 to both sides
x=6/7
