Step-by-step explanation:

-\frac{2}{3} a+\frac{5}{6}a-\frac{1}{6}

=-\frac{4}{6} a+\frac{5}{6}a -\frac{1}{6}

= \frac{1}{6} a-\frac{1}{6}

Answer:

\frac{( - 2)}{3} a +  \frac{5}{6}a -  \frac{1}{6}  \\   = \frac{(- 4a) + 5a - 1}{6} =    \frac{(a - 1)}{6}

In a sample of n = 6 scores, 5 of the scores are each above the mean by one point. Where is the 6th score located relative to th
den301095 [7]

The mean of a dataset is the sum of all data elements divided by the count of the elements.

The location of the 6th score relative to the mean is 5 points below the mean

Let:

\bar x \to<em> Mean</em>

a \to<em> 5 scores</em>

b \to<em> 6th scores</em>

Given that:

n = 6

The 5 scores that are 1 above the mean implies that:

a = \bar x + 1

The mean of a dataset is calculated using:

\bar x = \frac{\sum x}{n}

So, we have:

\bar x =\frac{5a + b}{6}

\bar x =\frac{5(\bar x + 1) + b}{6}

Open brackets

\bar x =\frac{5\bar x + 5 + b}{6}

Multiply both sides by 6

6\bar x =5\bar x + 5 + b

Make b the subject

b = 6\bar x -5\bar x - 5

b = \bar x - 5

This means that the 6th score is 5 points below the mean
