Answer:
Explanation:
The <em>average</em> is the mean. It is calculated adding all the values and dividing the sum by the number of values (data):
For the students who took the test the day before you, you can write:
Where n is the number of students who took the test first.
Thus, when the average was 69 the equation is:
When you take the test, the n + 1, the new average is 70, and the sum of the scores raised in 95 points:
Now you have a system of two equation and two unknowns, so you can solve it.
Clear the sum of the scores from the first equation:
Subsitute in the second equation:
Solve for n:
Thus, when you include your self the number of students who took the test was 25 + 1 = 26.

Step-by-step explanation:
Given
------- on or off
Required
Determine the number of codes to be programmed
Since each switch has any of the on or off controls (i.e on or off), then:
The first switch can be coded in any of the 2 controls
The second switch can be coded in any of the 2 controls
The third switch can be coded in any of the 2 controls
<em>Up till the ninth switch</em>
<em></em>
<em>So, we have that:</em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
Hence, there are 512 possible codes
