Answer:
(a) 1, 2, 3, 6, 8
Step-by-step explanation:
Given
Required
The sequence of hours worked each day
<em>See attachment for options</em>
From the question, we understand that:
This means that, the middle number is 3 (when sorted)
So, we can conclude that (b) and (c) cannot be true because their middle numbers are 6 and 5 respectively
Next, is to determine the mean of (a) and (d)
The mean of a data is calculated as:
So, we have:
(a)
(d)
Option (a) is true, because it has:
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
The exponent or power of a number represent the multiplication of the that number to the power times.
Let suppose a number 2 has the power 2. Then it will be equal to,
Similarly, 3 times of number 2 equal to the number 2 with exponent 3.
The expression is m times, m times, m times, m times, m. It can be written as,
The number m is total 5 time multiply by itself. Thus, the exponential form of the above equation is,
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
