We need to find the mean of a set of five values.
In order to do so, we need to add all the values, and then divide the result by the total number of values.
So, adding those values, we obtain:
Notice that since they are all negative values, the result is the sum of their absolute values with the minus sign.
Now, since the total number of values in the given set is 5, we need to divide the previous result by 5. We obtain:
Answer:
After solving the compound inequality we get
Option B is correct.
Step-by-step explanation:
We are given compound inequality:
We will first solve the inequalities to find the value of x, then will draw the graph.
So, after solving the compound inequality we get
Now, the number line will be as shown in figure.
The description as given in options is:
A number line goes from negative 10 to positive 10. An open circle appears at negative 4 and positive 5. The number line is shaded from negative 4 toward negative 10. The number line is also shaded from positive 5 toward positive 10.
so, Option B is correct.
