You don't even have to look up the definition of 'standard deviation'. You only
have to remember that 'smaller standard deviation' means 'less spread-out'.
First, let's find the mean (average). It's not supposed to change:
1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = <u>80 and 1/7</u> .
Now, just pick 7 scores that total 561 and are all bunched up.
The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.
Let's say <u>77, 78, 79, 80, 81, 82, and 84</u> .
Answer:
(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)
Step-by-step explanation:
I am pretty sure
The graph looks accurate make sure you create a table of values and clearly dot the points at (0,-3) and (2,-3).
Answer:
Step-by-step explanation:
For this case we have two points given (-1,6) and (1,5)
And we want to complete the point slope equation of the line:
We need to find the slope and we can use the following formula:
And replacing the info we got:
And then the equation would be given by:
And our final answer would be:
