the straight up answer is -12/5
Sort the data into this order:
2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2
^
there are 10 data points in total, therefore the Interquartile Range = between the 5th and the 6th numbers, which are 5 and 6
(5+6)/2= 5.5
2 because the square root is 12 and the distance is 12 units
C expression equivalent to -3*(4/-5)
Step-by-step explanation:
We apply the log rule that states that if there is a number multiplied by a log, the number becomes exponent of the argument of the log:
3 = log(8) + log(x^3)
Now we have sum of logs. Another property tells us that 2 logs with the same base a, that are added together, are equal to the log in base a of the product of the arguments:
3 = log(8x^3)
Now for definition of log:
10 ^ 3 = x^3
Therefore:
x = 10
